PC300/PC400 Front Idler Assembly for Bulldozer - 50000 PCS/Month
The keyed joint connecting the idler to the axle provides an expanded bearing surface and enhanced torque transmission. This design not only boosts reliability but also synchronizes the idler's service life with other undercarriage components. As the axle rotates inside fixed bearings, friction and wear are significantly reduced, further extending durability.
An extended service life of the track system translates to fewer replacement cycles, directly decreasing workers' exposure to safety hazards during maintenance.
The idler is crafted using either the alkali phenolic resin sand or sodium silicate-bonded sand casting process. After undergoing heat treatment, it achieves a minimum surface hardness of HRC48-58 with a hardened depth of 4-6mm (HRC45), enabling it to deliver exceptional impact resistance and wear resistance even under harsh working conditions.
Further refined on a CK5110 large-scale precision CNC vertical lathe, the idler boasts precise dimensional accuracy and superior surface finish quality. This comprehensive manufacturing approach ensures that the finished CHT idler delivers reliable stability and a guaranteed service life.
- Reduces bearing pressure by 50%: Eases bearing loads and significantly extends component service life.
- Heavy-duty rock guard: Robust stone shields block soil, rubble, and debris to prevent damage to critical parts.
- Expanded bearing surface & optimized oil distribution: Enhances overall track system performance and operational stability.
- Splined connection (idler + shaft): Improves reliability and synchronizes the idler's lifespan with other undercarriage components.
- Detachable bearing blocks with bushings: Allow removal without disassembling the track, minimizing maintenance time.
- Dedicated lube injectors: Precisely supply lubricant to high-wear surfaces, reducing friction-related downtime.
- 50% reduced bearing stress: Directly lowers bearing loads and extends component life, cutting replacement costs.
- Rotating shaft + stationary bushings: Minimizes contact stress and wear, reducing unplanned stoppages.
- Prolonged track system lifespan: Lowers mining operational expenses by reducing frequent replacements and downtime.
