Inner Ring

Built around the service demands of rock drilling machinery, the Inner Ring (OEM 0516 4100 26) 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 BOLTEC 235 and BOLTEC MC; final fit should be confirmed against the machine configuration or serial information. This aftermarket option is intended to support planned maintenance and faster parts sourcing while preserving the required application fit. Controlled geometry supports dependable assembly at the joint and helps prevent excess movement that could accelerate wear of surrounding parts.
