If I need the bearings going with nothing but only low friction, what kind of lubricating do you recommend?
Manager Reply:
The grease helps to protect the bearing and extend the service life. If you seek the ultimate flexibility, we recommend oil lubrication, and a more extreme approach is to apply no oil or grease. That can greatly improve the flexibility of the bearing unfortunately with increased noise and shortened service life.

My students are designing a model F1 racing car at school. They have decided to use a fixed axle and bearings in the wheels to reduce friction. Should they be looking to use a very small bearing e.g 1mm ID to achieve maximum efficiencey or would a larger bearing say 3mm ID be better? The car weight is limited to 55g minimum and will race over 20 mtrs. Would applying a speed lube like the one skate boarders use also improve efficiency? Have estimated bearing will rotate at approx 7000rpm
Manager Reply:
The smaller the bearing¡¯s inside diameter is, the faster the limit speed can be. The bearings with 1 mm inside diameter and with 3 mm inside diameter can reach the limit speed 80,000rpm and 115,000rpm respectively. If a longer service life of the bearing is expected, the grease lubrication should be for your choice. If more flexible operation and less friction is expected, the oil lubrication should be for your choice.

I am building a prototype which requires 20 off Ball bearings preferably 4x8x3 with the following attributes: non-magnetic essential, high speed to 100,000rpm, low friction, weight loading is not high, long life. I will also require 100 off Ball Bearings 5x10x4 with the following attributes: non-magnetic essential, max 50,000rpm, low friction, low weight loading but must withstand fast acceleration & deceleration over 100mm and reversal of direction of travel, long life. Dimensions of all bearings may be changed within 1mm if this suits commonly available products.
Manager Reply:
We also highly recommend ceramic bearings which is totally magnetism-free and quite high in the rotating speed. I¡¯m sure this kind of bearings will completely satisfy your needs.

Name:Steve Johnson

For a new design I need an ultra-low friction ball bearing. Radial load is 300 grams max., no axial load, speed is 300 RPM max., I.D. between 8mm and 30mm, width between 3mm and 11mm. Lifetime is not an issue. I would expect to use a light oil. This is a low-dust (lab) environment, so I wouldn't think seals are important. My question: How does inside/outside diameter and width affect friction?
Manager Reply:
For a low-friction bearing, what matters most is its quality and lubrication performance rather than its size. In your case, I highly recommend lubricant Shell 12#, which I mentioned before, and MR148 bearings.

Name:A.buckingham

I'm looking for a small bearing in width to take a load of 15-20kg axial and the radial load of a motor the bearings that i can find are normal radial bearings but not sure if they would take the load required, the bearing will only be rotating about 5mm per second. Angular contact bearings are mostly too wide for my prototype, I'm looking for a bearing that measures. 5x16x5 Have you anything of that description?
Manager Reply:
Certainly, the deep groove ball bearing can not bear the axial force. The best choice will be the angular contact bearing. The angular contact bearing size 5x16x5 is rare to see, but it is not impossible to produce. Please let us know the quantity of that type of bearing you need, so that we may offer you some help.

the differences between the full Ceramic Bearing and Hybrid Ceramic bearings ?
Manager Reply:
This is the introduction about different features of two types of bearing.

1,Full Ceramic Bearing
The advantages of full ceramic bearing are rust resistance, corrosion prevention, flexible rotation without demand for grease, abrasion resistance with longer service life. However, it will cost you considerably high price, as normally its price is around five times of ceramic hybrid bearing.

2,Hybrid Ceramic bearings
Compared with full ceramic bearing, the ceramic hybrid bearing is easy to rust for its bearing ring is made of metal. Additionally, it needs supply of grease, otherwise, it will be easily damaged. But the price is relatively lower than that of full ceramic bearing.

The bearing I am looking for is going to be used in a Fishing Reel, and it needs to running very freely with very low noise. The Reel uses two Bearings on either side of the Spool, and needs to run freely in both directions. The Dimensions of the Bearing are 0.500" OD, 0.250" ID, and a width of 0.1875"Which bearings would you recommend for this application. (ceramic?,steel?,shielded?, nonshielded?, lubricated or non lubricated?Also can a Needle bearing be used in this application, and which is smoother, the Ball Bearing or the Needle Bearing.Hope to hear from you soon.
Manager Reply:
We have a great number of customers of Fishing Reel, and we have rich experience in this industry. First, I do not think you have to choose the flange bearing, for the common ones are good enough. Generally speaking, the customers of Fishing Reel enjoy three types of bearings: chrome steel bearings, stainless steel bearings and stainless steel ceramic bearings. All the three types boast their own features with different prices. I do not know your budget, so I can hardly make a choice for you. As to sealing, generally, you can choose the metallic seal which is the most common. As to lubricating, I recommend you two types: oil lubrication and oil-less lubrication, and I can provide two samples for you at the same time. I suppose it is better to have them tested by yourself instead of me, do you agree? I do not recommend needle roller bearings, as they are not suitable here.

my son and a lot of his friends enjoy long boarding my son needs lowest friction 608 sealed bearings, which of your skateboard bearings would give him an "advantage" and what is the minimum number he may order with view to supply to skaters in New Zealand I can request quote on line depending on your reply to this message.
Manager Reply:

We are the manufacturer of skateboard bearings, not retailers. The minimum order quantity is generally 1,000pcs, so I can not sell bearings to you. But I can introduce one of our Australian clients to you, who purchases our bearings to sale, and they may be helpful to you. About your another question, you can have two options if you want to get low-friction bearings. 

1. You can use oil lubrication instead of grease lubrication, but this may shorten the service life of bearings . 

2. if you select oil lubrication, and use ceramic hybrid bearings, that will be the most suitable for you, because ceramic materials are lighter and more durable.

Name:Aodhan

My name is Aodhan and I'm a student in Tallaght Community School, Dublin, Ireland. We recently entered a competition called http://f1inschools.com/. At the regional finals last week we did excellently winning two awards and qualified for the national finals on the 7th of April. The race involves a 20metre drag style race where both reaction times and speed are tested. We used normal bearings in our last race and now we want to use ceramic bearings because they would be lighter and faster. The inside diameter of the previous steel bearings we had was 3mm (diameter 3mm carbon fiber axel), the outside diameter was 6mm and the witdh of 4mm. Could you possibly recommend what type of bearings we should use as we want our car to be as light and fast as possible. Your input would be much appreciated. If you have the required ones we will purchase them from you - possibly a few sets so we can test each. Do you also deal in axels to suit these bearings?
Manager Reply:
We are not very familiar with your industry, but a school in Canada have bought our ceramic bearings. for participating in this competition. They bought full ceramic bearings and they told me that full ceramic bearings are the most appropriate according to their experience, and are you agree with this point of view? Full ceramic bearings have the self-lubricating function, no need of oil or grease lubrication, and ceramic material is lighter than metal, which guarantees faster speeds.

What is the difference between open and shielded bearings?
Manager Reply:
open bearing used for very clean occasion , because of no shielded so it is very easy add oil . However most of our customers choose shielded bearings which have dustproof function.

Name:ilhan eryılmaz

Hello, I request is your gaziantep turkey ilhan Is it possible to send me price list of products
Manager Reply:
I’m sorry that I can’t give you a pricelist, because our quotation is based on the quantity of orders. For example, you see, for the same model of bearings, the prices for 100 PCS and 10,000 PCS are quite different. Therefore, you are adviced to tell me the details of the required bearings, such as model (you can inquiry it from here) and quantity, so that I can offer you the best price and a precise date of delivery.

For different thrust ball bearing sizes please refer to our website by click the link. All the thrust ball bearings on our table could be manufactured as ceramic thrust ball bearings. referring to here for detailed introduction of ceramic bearing.

Name:Roger Castle-Smith

I am using 3 conventional ball bearings size 1/8" x 3/8" x 7/64" in a clock. One is causing a problem. It is in a clock which I made, all gold plated ! It supports a balance wheel & other parts on a single arbor (shaft) which is vertical. The top end of the arbor runs in an identical bearing with a negligible load as it is only a "locating" bearing. Rotation is oscillatory through about 300 degrees with a peak-to-peak period of about 1.5 seconds. The load on the bottom bearing is almost entirely axial with the oscillating assembly weighing around 300 grams at most. After some 5 months running the bottom bearing fails due to micro welding between balls and raceways, a problem which is well known to horologists in the UK. The race does not seize completely but a distinct roughness can be felt when removed from the clock and rotating by hand. Then washing the bearing removes microscopic particles but this does not last long. I am led to believe that a hybrid race would get over the problem. Ideally I want it to run dry to avoid the spread of an oil film over the surrounding gold. Also ideally the race should be of the existing size, as above, to avoid having to make new mountings. Will you please comment on (1) Would a hybrid race be eminently suitable for my clock ? (2) Any problem over running dry as the loading is quite light ? (3) If hybrid an OK choice, then can you supply in the same size as existing ? (4) If I were to buy say 6, then what cost ? (5) If cannot supply exact size, then nearest ? Thanks. Roger
Manager Reply:
The hybrid bearing need oil or grease lube to run. As you would like this bearing run dry to avoid the spread of an oil film over the surrounding gold, we recommend you use full ceramic bearing which could self-lubricate when rotation. The bearing you need is R2-6 bearing which we could manufacture. For quotation, please contact our sales person.
