KMS Bearings produces 4 Bolt Flange Blocks from PBT, a glass filled reinforced engineering polymer, that will never corrode or rust. When inserted with a KMS 316 Stainless Insert ball bearing, they provide superior corrosion resistance compared to any mounted unit offered today.
Blocks are molded from a high grade of glass-filled PBT polymer. The block's spherical bore is machined for concentricity and proper fit of the insert bearing. The last step in manufacturing is machining the solid base for flatness.
CNC machined bearing rings, polymer cages and 316 Stainless balls are used in the manufacture of KMS insert ball bearings. This type of bearing is intended primarily to reduce friction and permit free movement of turning parts. They are best suited for moderate loads and low speeds.
