Back-Up Ring

Built for dependable performance in heavy-duty drilling applications, the Back-Up Ring (OEM 4350 2650 10) is intended for maintenance of compatible Atlas Copco drill rigs, drifters and support systems. Its primary role is to support, locates or spaces moving components so shafts, gears and adjoining parts remain correctly aligned under load. The compatibility data covers applications such as DHR 6H, DHR 6H-SH and FLEXIROC D65 -10SF.

Operational durability is supported by radial or axial loading, sliding contact, vibration and repetitive movement. Construction based on wear-resistant bearing surfaces manufactured to controlled dimensional tolerances helps the part retain its functional geometry under repeated use. As a result, it helps preserve running clearance, reduce unwanted movement and protect adjacent components from irregular wear.

Backed by Delkom’s specialization in alternative rock-drilling spare parts, this component is intended to support efficient maintenance and reduced downtime. Contact Delkom with reference 120 101 228 for supply and technical cross-checking.
