Front Idler Roller For Morooka Undercarriage

The Front Idler Roller for Morooka MST2200 undercarriage is a precision-engineered component designed to support and guide the track system under heavy load conditions. It matches OEM specifications for dimensions, bearing housing geometry, and seal interface, with a roller diameter of 210 mm and a shaft diameter of 60 mm, as confirmed by the supplier's technical drawings. The roller body is manufactured from medium-carbon steel with a hardened surface layer, and the internal bearing assembly uses sealed spherical roller bearings rated for radial and axial loads typical in mining and earthmoving applications.

This component is built to withstand continuous operation in abrasive environments, with a standard internal grease seal system rated for IP67 ingress protection. The surface hardness of the roller shell typically ranges from HRC 50 to HRC 58, a common specification for heavy-duty undercarriage rollers in tracked machinery. The supplier sources raw materials from certified steel mills and performs hardness and dimensional inspections at each production stage, though no third-party material certification is provided in the listing. The design is specific to the Morooka MST2200 model and is not interchangeable with other Morooka series without verified dimensional alignment.

Buyers include construction equipment distributors, tracked machinery repair shops, and mining fleet operators in Southeast Asia, Australia, and South America who require direct replacements for worn or damaged rollers. The product is supplied as a complete assembly, including bearings, seals, and mounting hardware. Packaging is in wooden crates with corrosion-inhibiting paper, and the supplier confirms batch traceability via internal part numbering. Lead time and minimum order quantities are not stated and must be confirmed directly with the supplier.
