KML Bearing USA Pressed Steel Mounted Bearing Units are manufactured to KML specifications in ISO9001 and TS-16949 certified facilities. KML Mounted Bearing Unit housings are made from progressive die stamped steel. KML Pressed Steel Mounted Bearing Unit product line is available in many different housing styles with various attachment methods and positions. Where applicable, all KML Pressed Steel housings come as a complete set ready for insert bearing installation.

The insert bearings’ inner ring, outer ring and balls are produced using vacuum degassed 52100 bearing steel. These components are heat treat hardened to produce a durable wear surface on the balls and ball tracks. KML uses cold rolled steel for ball retainers and shields. The Pressed Steel Mounted Bearing Units almost exclusively use narrow inner ring insert bearings with a flush back face.

The KML Bearing USA Pressed Steel Mounted Bearing Units are generally non-relubricatable. The insert bearing is available in a set screw or eccentric locking collar design that is factory sealed. All KML Pressed Steel Mounted Bearing Units are factory lubricated using Chevron SRI#2 grease with about 30-40% grease fill. Some 3 and 4-bolt hole round flange sets are available with a grease zerk in the housing and a re-lube insert bearing.
