Description

Built around the service demands of rock drilling machinery, the Expanding Shaft (OEM 3222 3255 89) provides an aftermarket replacement path for the rotation and drive train. Its role is to hold, locate or space connected parts so the assembly remains correctly positioned during drilling-machine movement and vibration.

Cross-reference data lists applications including FLEXIROC T35 and FLEXIROC T40; final fit should be confirmed against the machine configuration or serial information. For overhaul and repair planning, the component provides a competitive alternative to original-supply-only purchasing. The locating and contact surfaces are intended to maintain consistent fit so connected parts remain securely positioned under changing mechanical loads.

Supported by Delkom’s experience in alternative rock-drill and drill-rig spare parts, this component is supplied for professional mining and tunneling maintenance worldwide. For availability, pricing and an application check, quote Delkom reference 120 400 184 and OEM reference 3222 3255 89.
