Limit Bushing

Built around the service demands of rock drilling machinery, the Limit Bushing (OEM 551 560 75) provides an aftermarket replacement path for the boom positioning and support assembly. Its function is to guide relative movement and support localized loads while preserving the intended fit between adjoining machine parts.

It gives maintenance teams another sourcing path for the referenced application without compromising the need for dimensional and functional compatibility. Accurate fit helps distribute load across the bearing area and maintain the intended clearance as the connected mechanism cycles under load. Cross-reference data lists applications including DD311 and DD311-40; final fit should be confirmed against the machine configuration or serial information.

Delkom combines rock-drilling spare-parts expertise with broad export capability for mining and tunneling customers. For purchasing support, bulk requirements or fitment confirmation, use Delkom reference 110 400 215 and OEM reference 551 560 75.
