Triangular Spline Bushing (Part No. 3201 1957 03) – Suitable for Epiroc COP 22U Rock Drill

The Triangular Spline Bushing, part number 3201 1957 03, is a specialized wear component designed for use in the Epiroc COP 22U rock drill. This bushing serves a critical role in transmitting rotational force from the drive mechanism to the shank adapter, while also maintaining precise alignment during high-impact drilling operations.

Description

Featuring a triangular internal spline profile, this bushing is engineered for secure torque transmission and minimal play under load. Manufactured from high-strength alloy steel or bronze (depending on version), it provides excellent wear resistance, dimensional stability, and durability under the extreme pressures and vibrations typical in rock drilling environments.

Its precision fit reduces mechanical backlash and protects adjacent components like the shank and piston, extending the service life of the drill and reducing maintenance frequency.
