Why KMS Mounted Blocks and Bearings are Superior:

KMS Bearings,lnc. produces mounted blocks from PBT, an engineering polymer, that will never corrode or rust. When fitted with KMS’ Plastic or AISI 316 Stainless insert ball bearing they provide superior corrosion resistance to any mounted unit offered today.

Thermoplastic Polyester (PBT) and AISI 316 Stainless are widely used in the food and medical industries. KMS mounted blocks and bearings can run in liquids or run dry at slow speeds.

A solid flat base prevents contaminants from entering the bottom of the housings. This flat surface cannot harbor objectionable dirt, mold or bacteria.

BLOCK CONSTRUCTION:
Blocks are first molded from a high grade of glass filled thermoplastic polyester (PBT). 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.

BEARING CONSTRUCTION:
Machined semi-precision rings, polymer cages and AISI 316 Stainless balls are used in the manufacture of KMS Plastic & AISI 316 Stainless 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 slow speeds.

MATERIALS
RINGS:
Plastic: Acetal
Stainless: AISI 316

BALLS:
Standard balls are AISI 316. When necessary, other types of balls are available on a special order basis.
