Expanding Shaft

Engineered for demanding surface and underground operations, the Expanding Shaft (OEM 3125 4952 80) 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. Supplied as an alternative spare part, it provides direct functional interchangeability and dependable performance at a competitive price.

Backed by Delkom’s expertise in alternative rock drilling and drifter equipment, this part reflects the quality we export to over 100 countries. Reach out for availability, bulk pricing and technical support.
