Within Under Carriage, Idler covers the front and rear idler wheels fitted to plant equipment tracked-undercarriages — covering front idler wheels (front-mounted track-tensioning idlers, with adjustable hydraulic or grease-track-adjuster mounting), rear idler wheels (where the equipment uses front-and-rear idler configurations), bottom idler rollers (which support the track between the sprocket and idler), and the matching idler shafts, bearings, and hydraulic-track-adjuster service parts.
Parts for Machines supplies idler wheels across the plant aftermarket — covering idlers for the major mini-excavator, compact track loader, skid-steer, and larger excavator and crawler-dozer ranges (including the equipment-specific idler patterns for Caterpillar, Kobelco, Komatsu, Bobcat, Takeuchi, Hitachi, Doosan, JCB, and the wider plant equipment population).
Product pages list the equipment make and model the idler is approved for, the idler position (front idler, rear idler, bottom idler roller), the idler diameter and width (must match the equipment's track gauge and idler-mounting position), the bearing type (sealed cartridge bearings for sealed-track applications; serviceable bearings for older equipment), the shaft and mounting specification, the rated load capacity (matched to the equipment's operating weight), and the OEM cross-reference where applicable.
For replacement of an existing idler, the OEM part number is the most reliable match. Where the OEM number isn't available, identify by the equipment make, model, year, and the idler's measured dimensions. Always replace idlers on both sides of the equipment at the same time — a worn idler on one side and a new on the other gives uneven track wear and uneven track tension.
