NSK’s Molded Oil solid lubricant bearings are preventing premature bearing failure on an IHT conveyor at a UK milk processing plant – saving GBP9,992 a year.

The IHT conveyor contained inaccessible bearings that were impossible to lubricate.

As a result, engineers were changing bearings every 10 weeks, resulting in downtime, labour and equipment costs of GBP9,922 a year.

An engineer from NSK’s Cost Savings Programme identified the problem to be water washout, which is common in food-processing applications.

Water washout is the tendency of lubricant to be flushed out of conventional bearings under repeated washdowns.

NSK’s Molded Oil bearings employ a solid lubricant that eliminates this problem.

As such, it transforms the performance of machinery, in terms of reliability, maintenance-free intervals and operation, in environments exposed to high humidity, corrosion and contamination.

Molded Oil can increase the operating life of grease lubrication in water-contaminated environments.

It also ensures operating environments are kept free of grease and removes the need for lubricant refilling, as Molded Oil provides a continuous supply of lubricating oil.

NSK recommended F-UC206 Molded Oil bearing inserts to overcome the failure modes and changing the housings for the bearings to Silver-Lube units.

Silver-Lube mounted bearing units are designed for use in industries where hygiene considerations and corrosion and chemical resistance are important: typically bottling and brewing, food processing, pharmaceuticals, fisheries and chemical processing.


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.
