COLLAR, SLEEVE

064 210 82 COLLAR, SLEEVE Functioning as a vital structural fastener, this sleeve is typically found on the feed beam of the rock drill. Its primary job is to securely anchor guide components or hose bundles, preventing any unwanted movement or misalignment. By maintaining a firm grip, it ensures that the drifter travels straight and true along its path.

Proper clamping force from this sleeve is essential for overall rig reliability and drilling accuracy. A loose or failing clamp can lead to excessive vibration, which accelerates wear on both the feed and the drifter itself. For example, if the sleeve fails to hold a guide shell in place, the resulting misalignment can cause the drill steel to bind, slowing down penetration and risking damage to the equipment.

Inspect the COLLAR, SLEEVE regularly for any signs of cracking or deformation, particularly around the bolt holes. If you notice that a guided component has become loose or rattles during operation, the sleeve may be worn or damaged. Always replace a compromised clamp immediately to prevent further damage and ensure safe operation.
