Expanding Shaft

The Expanding Shaft (OEM 3222 3161 76) is a precision-made alternative spare part for rock drills and drifter equipment used in the most challenging mining and tunnelling environments. It transmits rotational or linear force between drive and driven components, and its straightness and surface finish are critical to smooth, vibration-free operation.

Manufactured from hardened, precision-ground alloy steel, it resists bending, torsional fatigue and wear under sustained high-load drilling duty. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.
