II. Structural and Working Advantages
Integrated Structure: Pin body + single-sided yellow welded positioning ear plate to prevent circumferential rotation and loosening of the pin during heavy-duty operations
Built-in grease channel + external grease nipple for daily lubrication, reducing dry friction of the bushing
40Cr Overall heat treatment, surface fine grinding for wear resistance, resistant to impact from mining gravel and heavy-duty alternating loads.
Wear scenarios: Long-term heavy-duty lifting easily wears down the shaft diameter and causes ear plate cracking; parts must be replaced during boom overhaul.
Matching wear parts: Matching copper bushings, dust rings, and adjusting shims are stocked in sets.
