The idler (also called idler group, idler assembly, or idler wheel) is a critical undercarriage component for crawler heavy equipment including excavators, bulldozers, cranes, and drilling machines. Constructed from idler shell, shaft, O-ring, bi-metallic bushing bronze, and seal group.

• Cast using alkali phenolic resin sand or sodium silicate-bonded sand process
• Surface hardness reaches HRC48-58 with 4-6mm hardness depth (HRC45) after heat treatment
• Processed by CK5110 large-scale precision CNC vertical lathe for dimensional accuracy
• Designed to withstand high impact and wear resistance in harsh working conditions

• Reduces bearing stress by 50%, increasing component durability
• Robust rock guards protect against dirt and debris damage
• Extends crawler system life, lowering operational costs
• Optimized lubrication distribution enhances track efficiency

• Splined idler-shaft connection improves reliability
• Bearing blocks with bushings enable easy maintenance
• Dedicated lube injectors target critical wear surfaces

Extended operational lifespan reduces replacement frequency, minimizing exposure to safety hazards during maintenance.
