Caterpillar E200B Construction Machinery Bulldozer OEM Undercarriage Spare Parts 50Mn Steel Front Idler Assembly With Heat Treatment

The CHT idler delivers outstanding durability and safety via advanced design and precision manufacturing. Its keyed joint between idler and axle expands bearing contact, enhances torque transfer, syncs the idler's lifespan with other undercarriage parts (avoiding uneven wear), while the axle's rotation in fixed bearings cuts friction and wear to extend track system life.

Made via alkali phenolic resin sand casting or sodium silicate-bonded sand casting (for robust, dimensionally stable parts), it undergoes specialized heat treatment--achieving HRC 48-58 surface hardness and a 4-6mm hardened layer (HRC 45)--for strong impact and wear resistance in harsh mining/construction sites.

Final precision finishing on a CK5110 large CNC vertical lathe ensures top dimensional accuracy and surface smoothness. Longer track system life reduces replacements, lowering workers' maintenance safety risks--linking lasting performance to workplace safety.

• 50% reduced bearing pressure: Drastically reduces bearing load, extending component life by 2x or more and doing away with the hassle of frequent replacements.
• Splined idler-shaft connection: Locks in unrivaled reliability while aligning the idler's lifespan with other critical undercarriage parts--avoiding uneven wear that shortens overall system life.
• Heavy-duty rock guard: Acts as a rugged barrier against dirt, rubble, and debris, shielding vulnerable components from damage that would lead to costly repairs or replacements.

• Detachable bearing blocks with bushings: Enable removal and servicing without disassembling the track, trimming maintenance time by up to 40% and getting equipment back online quicker.
• Dedicated lubrication injectors: Supply precise lubrication to high-wear surfaces, preventing friction-related failures and cutting down on unplanned downtime.
• Expanded bearing surface + optimized oil flow: Boosts track stability and responsiveness, even in rough mining conditions where consistent performance is critical.

• Rotating shaft + stationary bushings: Reduces contact stress and wear, slashing unplanned stoppages that eat into profits and disrupt daily operations.
• Prolonged track system life: Lowers total mining operational costs by reducing downtime and the frequency of part replacements.
• 50% less bearing stress: Directly results in fewer bearing failures, reducing both parts costs and repair-related labor expenses.
