Expanding Shaft

Engineered for demanding surface and underground operations, the Expanding Shaft (OEM 3222 3042 04) is a premium aftermarket replacement for rock drilling and drifter equipment. 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. As an alternative replacement, it ensures reliable fit and function while offering significant cost savings over the original.

Delkom produces premium alternative rock drilling and drifter equipment and spare parts, shipped to over 100 countries worldwide. Get in touch for stock availability, bulk pricing and technical assistance.
