If I need the bearings going with nothing but only low friction, what kind of lubricating do you recommend?
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
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.
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?
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?
the differences between the full Ceramic Bearing and Hybrid Ceramic bearings ?
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.
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.
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?
i was looking for a fishing reel bearing sizes id-3mmxod 8mmxwidth 4mm and also 5mmx0d11mmxwidth 4mm. is it possible to get these in a higher than abce 7 rating and what would they cost? also will it help to upgrade the drag bearing(magnetic cast control)to help the spool bearing?
How do you get oil or grease into a shielded bearing?
I would like to know what the starting torque is for your 625 5x16x5mm Open Bearing Bore :5mm Outer Diameter :16mm Width :5mm
The application I want to use it in moves at a speed of less than 1 revelation per day but is constant.
Can you give me please a left around
these articles in a shop to buy?
Could please tell me the price ofthe bearings i have listed below, including post to - Newcastle, Aus
I would like to order 8 of each of the bearings which i has listed below.
Is this possible? please respond as soon as possible.
What is the difference between open and shielded bearings?
Hello, I request is your gaziantep turkey ilhan Is it possible to send me price list of products
My son at school have the following question
Under which 2 circumstances would you use oil instead of grease as a lubricant
Hi sir i need a bearing with the following attributes.
Size 5-10 mm ID (Shaft diameter)
Very High rpm 80,000-100,000 rpm
Weight 200-300 gram
Layout is horizontal
Please recommend the bearing with the minimum quantity and cost. It will be good if you can provide your few samples.
I want to use ceramic thrust ball bearing as a part of my experimental setup. Could you tell me what different sizes of ceramic thrust ball bearing you have? Also, could you point me which option on the bearing table is for ceramic thrust ball bearing?
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
