A Gold Star for NSK Silver-Lube Corrosion Resistant Bearings

As part of the NSK range of products, the RHP brand Silver-lube corrosion-resistant bearing series has been specifically developed for precisely these conditions, and has proved more than up to the job.

Due to changing conditions in these industries, components need to be robust and, ideally, maintenance-free, criteria that has informed the engineering design of the Silver-lube series.

Attention to detail

Silver-lube housing are made from PBT thermoplastic polyester resin, which isn’t just non-corrodible, but also resistant to detergents and a wide range of chemicals used I wash-downs. The smooth surface of the housings also helps to make wash-downs more effective, while the fact that housings are free from paint and coatings means there’s nothing which can chip or flake off and find its way into products.

Taking the heat

The bearing rings and balls themselves are manufactured from high-grade martensitic stainless steel, with austenitic stainless steel ball and cage, flinger and set screws. All seals are made from durable, heat-resistant silicone rubber, and the bearing inserts are charged with high-quality aluminium complex food grade grease, which is classified to NSF Grade H1.

For even greater sealing and protection, polypropylene end-covers can be fitted which are suitable for operating at temperatures from -20 to +90°C.

Engineered to perform

A choice of Silver-Lube bearings in pillow block, 2-bolt flange, 4-bolt flange and take-up unit configurators makes it easy to find the optimum solution for your bearing application.

However, NSK engineers can work with you to analyse critical points in your production process, measure and monitor efficiency and propose alternative bearing products.
