The splined connection between idler and shaft provides more bearing area and better torque transfer, increasing reliability and matching idler life with that of other lower works components. Rotating shaft within stationary bushings produces less contact stress and wear. Longer crawler system life increases change-out intervals reducing employee exposure to safety risks.

The idler is casted with alkali phenolic resin sand or sodium silicate-bonded sand process. Surface hardness reaches minimum HRC48-58 with hardness depth between 4-6mm (HRC45), after heat treatment process. The idler is able to withstand high impact and wear resistance under harsh working conditions.

Our idler is processed by CK5110 large-scale precision CNC vertical lathe, ensuring precise dimensions with high quality surface finishing. The fulfilment of these requirements ensures that the finished CHT idler provides stability and service life are guaranteed.

• Cuts bearing stress by 50%, thereby lightening bearing loads and prolonging component lifespan.
• Robust rock guards safeguard against harm caused by dirt and debris.
• It aids in reducing mining operational expenses by enhancing the durability of the crawler system and minimizing unexpected downtimes.
• By augmenting the bearing surface and improving lubricant distribution, it offers superior track efficiency.
