KML’s Thermoplastic Corrosion Resistant Platinum Series feature stainless steel insert bearings designed with wash-down purposes in mind, making them perfect for applications in meat, poultry and seafood processing and packaging plants, as well as beverage, brewing and bottling plants. The reinforced PBT (Polybutylene Terephthalate) is composed of 10% long strand glass fiber and contains a one piece 316 grade stainless steel bushing molded in place around the bearing bore which together gives KML Thermoplastic Corrosion Resistant Units superior strength.
KML Thermoplastic Corrosion Resistant Mounted Units are ideal for food service applications with maximum operating temperatures of 285-degrees Fahrenheit. The 440C grade stainless steel insert bearings are filled with Mobil FM 222 NSF H1 food grade grease for use in HACCP compliant facilities. The slinger, retainer, grease fitting and set screws are made from 304 stainless for improved corrosion resistance. The bolt hole insert washers, thread inserts and ball retainers are 316 series stainless steel to complete the corrosion resistant design.
The star of the Corrosion Resistant bearing insert is the KML Sani-Guard Sealing System. This system consists of a metal backed silicon rubber barrier seal that is designed to block dirt & moisture from entry while retaining the synthetic lubricant in the critical ball track cavity. The metal backed silicon rubber seal snaps into a groove in the outer race, preventing contact with the ball bearing retainer while improving the seal. The insert bearing’s unique construction is further enhanced by positioning a slinger that rotates with the outer bearing ring in front of the seal. This stainless steel slinger creates a labyrinth barrier channel, which when teamed with the seal creates the KML Sani-Guard Sealing System that protects the critical bearing races.
