The Dodge Ultra Kleen ball bearings employ a 100% stainless steel bearing insert and feature a sealing system and a ball retainer that retain lubrication and prevent washout in wet operating environments such as food and beverage processing. The sealing system, QuadGuard, consists of a triple lip seal and a rubberised flinger, keeping the lubricant in and contaminants out. A two-piece ball retaining cage, Maxlife, creates a grease compartment around each of the rolling elements, which provide constant contact between ball and grease so an oil film always exists to prevent wear, and minimise friction and heat. The stainless housing is made with 300 grade steel. Polymer housed versions have an added antimicrobial agent. For additional protection, the housings are machined with a groove to accept a snap-on polymer end cover to cover exposed, rotating shafts and create safer working conditions. The bearings are offered in a wide variety of stainless steel and polymer housings. The range is available in a broad range of imperial sizes plus metric sizes from 20 to 50mm.
