Wear-Resistant Component - Bucket Ear Bushing

2026-07-03

Bucket link bushing is a critical wear-resistant component installed on excavator bucket connecting link, used between bucket pin and link bore. It bears heavy impact and friction during digging, loading and mining operations, protecting bucket link body from rapid abrasion and extending the service life of your whole bucket assembly.

Our bushings fit CAT, Komatsu, Hitachi, Volvo, Doosan, Sany and all mainstream excavator models, widely applied in construction sites, stone quarries, mines and heavy earthmoving projects.

Outstanding Product Quality (Factory Direct Manufacturing)

High-strength alloy steel material
We adopt premium 40Cr / 42CrMo alloy steel with integral quenching heat treatment. Surface hardness reaches 48–55 HRC, featuring strong impact resistance and superior wear resistance. Service life is 30% longer than ordinary carbon steel bushings, effectively cutting your machine maintenance frequency.
Precision CNC finishing
Full CNC turning and internal & external cylindrical grinding for ultra-tight dimensional tolerance. Uniform built-in oil grooves ensure smooth grease circulation, avoiding Dry friction, seizure and bushing burning under continuous heavy loads.
Strict multi-stage inspection system
ISO9001 certified factory. Five rounds of inspections from raw material incoming to finished goods delivery, including hardness test, dimension check and wear resistance test. Factory pass rate exceeds 99.8% to guarantee consistent batch quality.
Full stock & custom service
Standard sizes in abundant stock for fast delivery. We support OEM & ODM customization according to your part numbers, drawings or samples, including flanged, thickened and special-size link bushings for direct replacement without modification.
