Description

Built around the service demands of rock drilling machinery, the Insulating Sleeve (OEM 550 395 51) provides an aftermarket replacement path for the rock drilling machine assembly. Its function is to guide relative movement and support localized loads while preserving the intended fit between adjoining machine parts.

The part supports cost-conscious maintenance strategies that require a reliable cross-reference option for professional drilling equipment. Application data associates this reference with DD320-40 and DD321-40; configuration and serial-number checks are recommended before purchase. The working surface is intended to withstand repeated sliding or rotational contact while keeping the mating components supported and correctly located.

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 110 300 136 and OEM reference 550 395 51.
