Product Description

Komatsu PC40 Construction Machinery OEM Heat Treatment Undercarriage Spare Parts Forge Steel Front Idler Assembly

The Komatsu PC40 Front Idler Assembly combines advanced design with precision manufacturing for exceptional durability and performance in heavy-duty construction environments.

Idler Function and Design

The CHT idler features a keyed joint between idler and axle that expands bearing contact area, enhances torque transmission, and synchronizes service life with other undercarriage components.
Manufactured through alkali phenolic resin sand casting or sodium silicate-bonded sand casting for dimensional stability in heavy-duty conditions.
Specialized heat treatment achieves surface hardness of HRC 48-58 with a 4-6mm hardened layer (maintaining HRC 45) for superior impact and wear resistance.
Precision finishing on CK5110 large-scale CNC vertical lathe ensures perfect dimensional accuracy and smooth surface finish.

Key Characteristics

Tech-Driven Durability

50% reduced bearing pressure extends component life by 2x or more
Splined idler-shaft connection prevents uneven wear
Heavy-duty rock guard protects against debris and damage

Efficiency-Focused Design

Detachable bearing blocks enable 40% faster maintenance
Dedicated lubrication injectors prevent friction-related failures
Expanded bearing surface improves track stability

Cost-Smart Engineering

Rotating shaft with stationary bushings reduces contact stress
Prolonged track system life lowers operational costs
50% less bearing stress means fewer failures
