Press Release - NSK's Silver-Lube

2005.07.19 <% if ( "" = "Top" ) then %> <% end if %> Many industries, from bottling operations to bakeries and food processing to pharmaceuticals, must adhere to rigorously maintained standards for hygiene and workplace cleanliness. That translates into frequent and thorough washdowns characterized by high pressure, high temperatures, lots of water, harsh detergents and corrosive chemicals. Obviously then, it is critical that the equipment used in these hostile environments be able to withstand the demanding conditions, and bearing assemblies are no exception. The Silver-Lube® series of bearing assemblies from NSK is designed and made specifically for these types of applications. Often a bearing assembly is only as durable as its housing. The Silver-Lube® housing is manufactured from Valox® 420, a high quality, 30% glass-filled thermoplastic polymer resin which offers exceptional strength, rigidity and dimensional stability. It is non-corrodible and can withstand repeated exposure to heat, ultraviolet light, pressure, water, detergents and a variety of chemicals without breaking down. As a naturally-coloured resin, there is no paint or coating to flake, chip or peel, and either contaminate the process, or result in premature housing failure. Its solid base also prevents the ingress of organic contaminants. Not only is the dense, smooth surface resistant to dirt, bacteria, and mould, ASTM G21-70 testing confirms that Valox® resins demonstrate significant fungicidal resistance as well. As durable and resistant as the housing is, the only thing that might outlast it is the Silver-Lube® bearing insert itself. Manufactured completely from QD51, a modified 440C type stainless steel, the bearing insert operating temperature range is -20°C to +90°C making it well suited to a host of applications. While permissible bearing speed is ultimately dependent upon shaft tolerances, Silver-Lube® bearings can operate up to 2900 rpm. To enable the bearing to slip easily over standard shafting, the inner ring bore tolerances are on the plus side of the nominal bore. The assembly is effectively sealed and charged with USDA H1 approved food grade grease. The stainless steel grease nipple allows periodic relubrication for an even longer trouble-free operating life cycle. The Silver-Lube® series of bearing inserts come in pillow block, take-up units, two bolt and four bolt configurations and are designed to accommodate initial misalignment due to mounting errors. Polypropylene end covers are available to fit all housings to either provide additional protection for the bearing in particularly harsh conditions or to meet safety requirements. Ultimately, the bottom line is performance over the long term. In countless operations where cleanliness is paramount, Silver-Lube® bearings have proven their worth by minimizing maintenance, reducing costly down time and maximizing productivity. <% if ( "" = "Bottom" ) then %> <% end if %> Posted by: Americas Admin << Back
