Import Bucyrus 49hr Caterpillar Md6640 Undercarriage — Buy in Bulk from Supplier in China

The Bucyrus 49HR Caterpillar MD6640 undercarriage is a heavy-duty track assembly designed for large-scale mining and earthmoving equipment, compatible with Caterpillar MD6640 Series machines. This listing covers the full undercarriage kit, including track shoes, bottom rollers, top rollers, sprockets, and idlers, with a warranty of 1 year or 2500 working days, whichever comes first. The supplier offers customisation options such as colour (standard black or customer-specified) and packaging in strong pallets or plywood cases to ensure safe transit.

Undercarriage components for this class of equipment are typically forged from high-strength alloy steel to withstand extreme loads and abrasive conditions, with heat-treated surfaces for extended wear life. Track shoes are usually hardened to 50-60 HRC for resistance to impact and abrasion, while rollers and idlers feature sealed bearings to prevent contamination. The Bucyrus 49HR model is engineered for operations in harsh environments, where durability and minimal downtime are critical.

These undercarriages are sourced by mining contractors, large construction firms, and equipment rental companies that require reliable replacements for high-wear parts. The supplier provides flexible trade terms, including TT and LC payment options, with delivery from stock or within 15-25 days after payment confirmation. Buyers should confirm compatibility with their specific equipment model and operating conditions before ordering.
