Product Desciption
Description:
1. Elasatomer Sealed Roller Bearing Bit
Cutting Structure:The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
Gauge Structure:Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Sealed Bearing Structure:1. Abrasion resistance and seizure resistance of the bearing are improved. 2.Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance.
