CIRCLIP

The CIRCLIP 422 272 90 (also indicated as 0335110409 and 422-272-90) is a precision-engineered retaining CIRCLIP designed for securing bearings, shafts, and mechanical interfaces on Sandvik drilling rigs, ROC-series platforms, and underground jumbos. The 422 272 90 RETAINING RING maintains axial positioning of components operating under high vibration, torque pulses, and contamination exposure typical of mining equipment.

This 422 272 90 RETAINING RING is manufactured from hardened spring steel with controlled elasticity, providing superior clamping force without deformation. Designed for long-term resistance to rock dust, hydraulic oil, and temperature cycling, it ensures reliable retention of rotating and sliding assemblies. OEM identifiers 0335110409 and 422-272-90 guarantee compatibility with Sandvik component groups.

The 422 272 90 RETAINING RING prevents axial movement of bearings, bushings, sprockets, and mechanical drive elements. Its secure fit protects against misalignment, early wear, and component ejection during drilling, feeding, and hydraulic system operation.

Inspect the 422 272 90 RETAINING RING for loss of tension, surface cracking, or groove wear. Replace 422 272 90 immediately if retention force decreases or axial play becomes noticeable.
