The Liebherr R9350 is a large mining excavator designed for demanding quarrying, mining, and heavy-duty earthmoving applications. Its undercarriage operates under extremely high loads, making durable track rollers essential for stable travel, track guidance, and long-term machine performance.

Xiamen Doozer supplies high-quality aftermarket track rollers for Liebherr R9350 excavators. The track roller is designed to support the machine weight while guiding the track chain along the undercarriage. It works together with the track chain, carrier rollers, front idlers, sprockets, and track shoes as part of the complete crawler system.

The R9350 uses a heavy-duty D12 track system with forged double-grouser track components. Liebherr technical information specifies nine track rollers and two carrier rollers per side frame. This configuration is designed for demanding mining conditions and continuous operation.

Our R9350 replacement track rollers are manufactured from high-strength steel and processed with controlled heat treatment. Precision machining helps maintain consistent running surfaces and mounting dimensions, while wear-resistant surfaces are designed to withstand repeated contact with the track chain.

A properly manufactured track roller can help reduce abnormal track movement, excessive vibration, and uneven wear. Regular inspection is important because damaged seals, worn running surfaces, or excessive roller clearance can affect the entire undercarriage system.

Xiamen Doozer provides aftermarket undercarriage components for large mining excavators, including track rollers, carrier rollers, front idlers, sprockets, track chains, and track shoes. We focus on stable manufacturing quality and factory-direct supply for international customers.

Because R9350 configurations may vary by machine generation and serial number, customers should confirm the excavator serial number, existing roller dimensions, track configuration, and part reference before ordering.
