NSK has combined the reliability and maintenance-free benefits of its Molded Oil lubrication technology with the corrosion resistance of stainless steel in a range of ball bearing units.
The units are for use in environments where cleanliness and high resistance to corrosion are priorities, such as food and beverage applications, in fryers, meat and fish processing and packaging, and bottling applications.
The bearing units are manufactured in Martensitic stainless steel to suit the working environment of the application, and to cater for the type of cleaning agents encountered in washdown processes.
They reduce the cost of ownership for users with their resistance to corrosion and chemical attack, and offer cost and time saving benefits of prefabricated bearing units, with pillow block and flange types available.
All of these versions are interchangeable with current NSK units, and also with ISO standard variants.
NSK's Molded Oil technology is a special solid lubricant that transforms the performance of machinery and equipment, in terms of reliability, maintenance-free intervals and operation, in environments exposed to high humidity, corrosion and contamination.
NSK claims that Molded Oil technology enables users to make cost savings by replacing existing, and often costly, methods of lubricating machine parts.
In real-world tests, Molded Oil offers more than twice the operating life of grease lubrication in water contaminated environments.
In addition, the technology means that operating environments are kept free of grease; and there is no need for refilling of lubricant, as Molded Oil provides a continuous supply of lubricating oil.
Molded Oil technology can be effective in environments such as food processing where oil related pollution must be prevented.
The technology also overcomes the problem of loss of lubricant due to water ingress.
Options on the stainless steel bearing units include the alternative (to Molded Oil) of a special USDA H1- compliant, food grade grease, and the fitment of a grease nipple to allow relubrication of the bearings.
