Bunting BB-16 is a self-lubricating, powdered metal bearing material typically used for heavily loaded applications. This bearing material has excellent compressive strength, wearability and is shock resistant.

This bearing is heat treated to a spec of HRB 70 min. and oil impregnated with an extreme pressure oil.

Typical Uses:
·  Off-road equipment
·  Backhoes, graders, and earth-moving equipment
·  Escalators
·  Automotive and railroad applications
·  Heavily loaded applications
