KML Bearing USA Corrosion Resistant Mounted Bearing Units are manufactured to KML specifications in ISO9001 and TS-16949 certified facilities. KML Corrosion Resistant Mounted Bearing Unit housings are available in 304 grade stainless steel or reinforced Thermoplastic. The housings are designed with solid base construction and reinforced bolt hole areas. KML Corrosion Resistant Mounted Bearing Unit product line is available in many different housing styles with various attachment methods and positions.
KML uses 440C grade stainless steel in all wear surfaces of the bearing races and balls. 440C grade stainless steel is heat treatable for increased surface hardness, dimensionally stable, corrosion resistant and durable which provides extended bearing life. KML uses 316 grade stainless steel for ball retainers and shields.
The stainless steel insert bearing features a labyrinth sealing system that is comprised of a metal backed silicon rubber excluder seal that is designed to keep the food grade grease in and contaminants out. The silicon seal is protected by stainless steel flinger installed on the inner ring in front of the seal contact surface. This flinger, due to centrifugal force during bearing rotation, effectively slings moisture and contaminants away from the seal area. The silicon seal is designed to allow used grease to purge past the seal into the channel between the seal and the flinger when new lubricant is carefully replenished.
All KML Mounted Bearing Units are factory lubricated using Mobil FM222 NSF H1 grease with about 30-40% grease fill.
Applications: The housings are available in Antimicrobial Thermoplastic or Stainless Steel depending on the specifications of the application. The load rating of the part number is determined by the insert bearing in the applicable Corrosion Resistant Mounted Bearing Unit series. KML Corrosion Resistant Mounted Bearing Units are suitable for use in various applications where they are exposed to moisture, sterilization, mild corrosive elements, organic chemicals and oxidizing agents.
