Spline Shaft

The Spline Shaft (OEM D-52040070) is a high-quality alternative spare part built for rock drills and drifter rigs working under the toughest mining and tunnelling conditions. 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.

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.
