NSK has unveiled Life-Lube, a range of bearing units for use in industries where contact with water and process fluids is unavoidable.

Life-Lube units are available in pillow block, two-bolt flange, four-bolt flange and take-up unit configurations, and are capable of accommodating initial misalignment from mounting errors.

The bearings are fitted with stainless steel flingers and nitrile rubber seals as standard, and offer proven reliability in the most hostile of applications.

Life-Lube housings are made from PBT thermoplastic resins which, in addition to being corrosion-proof, are resistant to detergents and a wide range of chemicals.

The housings are paint- and coating-free, which prevents chipping or flaking, and have smooth surfaces to assist in washdowns.

As a result, they are suitable for use in applications where cleanliness is paramount.

Bearing inserts in the Life-Lube range are manufactured from stainless steel, which provides superior corrosion resistance.

The inserts are lubricated with NSK’s oil-impregnated polymer, Molded-OiI.

Oil is delivered on demand from this material and provides ample lubrication in the bearing for extended periods.

Molded-Oil solid lubricant resists contamination and addresses the problem of loss of lubricant due to water ingress, a feature of particular importance on machines used in food processing, as it provides the benefits of increased reliability and longer maintenance-free intervals.

Molded-Oil bearings can also reduce the total cost of ownership of equipment and machines, by eliminating the downtime associated with relubrication intervals, and by cost savings achieved through reduced requirements for replacement bearings and bearing lubricants.


NSK, a global leader in motion and control products, has developed and continuously upgrades four core technologies: tribology, material engineering, analysis technology and mechatronics, to provide the platform for the company’s innovative product developments. This technology platform provides the basis for the design of NSK’s rolling bearings, automotive components and precision parts. In addition, by integrating these advanced technologies, NSK is able to respond quickly and effectively to customer requirements across all key sectors.

NSK is a driver of new technology developments, with a full line-up of products spanning general industrial, automotive and precision parts industries. These include bearings for mechanical and electrical machinery, IT and aftermarket; innovative automotive products such as electric power steering (EPS) automatic transmission components, steering columns and other steering related products; and precision linear motion components such as linear guides, ballscrews, X-Y tables, mechatronic products and Megatorque motors.
