OEM Replacement CAT B30 B60 B90 Bushing Alloy Steel Guide Sleeve For Construction Breaker

CAT B series hydraulic breaker bushing, also named front guide sleeve, is an essential front wear component for CAT B series medium hydraulic breakers covering all models B12 to B90. It guides chisel to run concentrically and is widely used in municipal demolition, road reconstruction, landscaping and secondary quarry rock crushing projects.

Made of solid 42CrMo alloy steel via integral forging and multi-stage hardening heat treatment. Smooth precisely honed inner bore greatly cuts friction between sleeve and chisel shank during continuous high-frequency striking.

This guide bushing effectively prevents chisel tilt, abnormal vibration and seal damage. Strict CNC dimensional tolerance ensures direct OEM replacement without on-site modification, reducing extra maintenance cost.

All bushings go through hardness test, friction inspection and assembly fitting verification to reach OEM standard. Full model stock supports retail repair orders and bulk wholesale. Custom inner and outer diameter machining service is available for global machinery maintenance factories and spare parts dealers.
