We provide High-quality Mining Parts
EXCAVATOR & BULLDOZER UNDERCARRIAGE PARTSOptimal Combination
Fully comply with the RC strength design standard of Japanese mining machinery
- Track Roller: Shafts are made from forged alloy or rolled carbon steel and hardened over 3mm deep to 56-60 RC.
- Carrier Roller: Shafts are made of forged alloy or rolled carbon steel, quenched and tempered heat treated, hardened to 36-56 RC.
- Idler: Idler shells are cast or forged, depending on the design, then heat treated to 48-56 RC and machined to size.
- Sprocket : Are made to OEM fitment specifications and manufactured from cast steel, with the external tooth profiles deep induction hardened in excess of 50RC to provide long service life.
- Segment: Are made to OEM fitment specifications and manufactured by forging, with the tooth profiles being through hardened for extra toughness, better wear resistance and long service life.

PURSUIT
Top Roller
Carrier rollers serve to support the weight of the track chain and distribute the weight evenly across the undercarriage.
Track Roller
Bottom rollers absorb the machine’s weight and distribute it evenly on the tracks.
Idler
Idler ensures seamless movement and enhances the track’s durability and the complete undercarriage system.
Sprocket & Segment
Sprockets engage with the track chain, propelling the excavator forward.
Excavator & Bulldozer Top Roller
The carrier roller body is forged from two halves of high manganese alloy steel, and then hardened, machined, and welded together by friction or submerged arc.
