Precision tolerance machining ensures uniform fitting clearance, eliminating hinge shaking and abnormal noise and making cutting and slewing movements more stable and accurate.
Superior fatigue and peeling resistance enables it to withstand repeated underground impact and alternating loads, ensuring long-term inner-wall wear resistance and longer service life.
Excellent self-lubricating and low-friction performance reduces operating resistance, lowers hinge energy consumption, and improves mechanism flexibility and transmission efficiency.

Product Q&A
Q:Why does loose mechanism and enlarged fitting gap occur after long-term use?
A:
Long-term heavy-load swinging and abrasive dust wear the inner wall of the copper bushing, gradually enlarging the gap and causing hinge looseness. Regular lubrication and impurity cleaning can effectively reduce wear.
Q:How to solve overheating and jamming under high-temperature and continuous operation?
A:
Long continuous operation and failed high-temperature grease will break the lubricating oil film and cause dry friction and jamming. Shorten the grease filling cycle and avoid long-term extreme-angle operation under high temperature.
Q:What effect does frequent cutting-arm luffing-creeping exert on copper bushing?
A:
Repeated swing delivers alternating impact loads and causes inner-wall fatigue wear. Avoid long-time reciprocating impact at extreme working angles.
