The brake block of oil drilling rig is made of polymeric fiber with high wear resistance. The brake block supporting brake block rubs against the drum brake disc, controlling the tension pressure of the winch wire rope, and is an important component of the disc brake system of oil drilling rigs.

Product features

The brake block of an oil drilling rig is mainly used as a supporting product on the brake belt of an oil drilling rig winch, which mainly plays a braking role.

Type

Molded brake block, a brake block made of velvet fiber as the skeleton material, has a hard texture, a high coefficient of friction, and sensitive braking. It is usually used for drilling rig brake hubs with anhydrous cooling devices.
