Expanding Shaft

Description

Engineered around the operating needs of surface and underground drilling equipment, the Expanding Shaft (OEM 3128 3034 35) is an aftermarket component for the feed and drill-carriage mechanism. It contributes to mechanical integrity at the connection point by maintaining the intended position, preload or separation between components.

Controlled geometry supports dependable assembly at the joint and helps prevent excess movement that could accelerate wear of surrounding parts. For overhaul and repair planning, the component provides a competitive alternative to original-supply-only purchasing. Listed compatible equipment includes FLEXIROC T35 and FLEXIROC T40. Verify the exact machine variant before installation or ordering.

Delkom supports drill-rig and drifter maintenance with alternative components for demanding mining and tunneling applications. To check fitment, lead time or bulk pricing, share Delkom reference 120 400 041 and OEM reference 3128 3034 35.
