Description

Engineered as a durable aftermarket solution for drilling equipment, the Back-Up Ring (OEM 4350 2650 11) is an aftermarket replacement for Atlas Copco rock drilling and related equipment. It supports, locates or spaces moving components so shafts, gears and adjoining parts remain correctly aligned under load. Listed compatibility includes DHR 6H, DHR 6H-SH and FLEXIROC D65 -10SF.

Its design focuses on radial or axial loading, sliding contact, vibration and repetitive movement. The use of wear-resistant bearing surfaces manufactured to controlled dimensional tolerances supports consistent fit at the relevant interfaces and reliable operation after replacement. In practical maintenance terms, this helps preserve running clearance, reduce unwanted movement and protect adjacent components from irregular wear.

Delkom supplies this item as a cost-conscious alternative for maintaining Atlas Copco drilling machinery without compromising the focus on fit and service reliability. Reference 120 101 226 for availability and quotation requests.
