Product Description

Bimetal Liners


The b-metal liner is composed of two layers and fixed tightly. The outer sleeve is forged steel with abrasion resistance, it adapts the technology of centrigugal forging;  the inner sleeve is high chromium iron with wear&corrosion resistance, after heat treatment, the hardness can reach to a lever of 62 RC.

The bimetal liners produced by us strictly control the tolerance, assure the easy installation, inner sleeve is highly polished with abrasion&corrosive resistance, can used in various bad working environment with longer service life.
