Bearings play a critical role in the beverage industry. Properly designed bearings ensure longer equipment uptime and reduce maintenance costs. The metric-sized Sealmaster® PN Gold bearings (an extension of the Corrosion Resistant Engineered Solutions series (CRES) bearings) are engineered for the food/beverage industry using various materials and patented sealing systems that extend life and optimize performance in corrosive conditions while meeting CIP (Clean in Place) and SIP (Steam in Place) sanitation requirements.
These bearings include metric bore sizes for mounted ball bearings (20 to 60 mm) and “ER” cylindrical OD ball bearings (20 to 60 mm). Designed with brewery chemical and cleaning solutions in mind, they have patented multiple-lip seals and specialty coatings, and are available with features like bolt-on end caps and backside shields.
The bearings are engineered with high-phosphorous, electroless-nickel-plated inner and outer races, and multi-directional triple-lip seals. A unique zone-hardening process on the inner races hardens only the region under the ball path, for improved lock reliability through less distortion at setscrew locations. The triple-lip contact seals provide multidirectional sealing to retain lubrication and exclude contaminants. Grease cavities in the seal assembly are factory filled with H1 Food Grade lubricant. A Tapered Land profile machined on the outer race redirects lubricant back into the raceway for better lubricant circulation. A land-riding retainer design allows 360-degree grease circulation around the rolling elements for better grease retention and use.
Solid base housings on the bearings are machined from 316 stainless steel or high-strength composite with minimal gaps for fillings. Stainless steel bolt ferrules reinforce the bolt holes on composite bases for high load capacity and strength.
