Pillow Block

Intended for equipment that operates under repeated load, vibration and contamination exposure, the Pillow Block (OEM 550 129 74) supports 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 working surface is intended to withstand repeated sliding or rotational contact while keeping the mating components supported and correctly located. It gives maintenance teams another sourcing path for the referenced application without compromising the need for dimensional and functional compatibility. Compatibility records include DX700 and DX800. For best results, check the part reference together with the machine model and serial data.
