Products Description
Our mining truck wheel rims abandon low-grade ordinary carbon steel and eliminate hidden risks of welded structural fracture. All wheel hubs adopt integrated forging technology, matched with dual heat treatment processes: full-body tempering + high-frequency surface quenching. This design retains excellent core toughness while achieving high surface hardness, balancing outstanding impact resistance and anti-fatigue performance to cope with extreme heavy-load mining working conditions. We supply segmented multi-piece mining profile steel rims and integrated cast mine car rims, fully compatible with mainstream Caterpillar, Komatsu, Belaz and domestic wide-body mining vehicles.
Why Choose Our Mining Truck Wheel Rim?
One-stop heavy machinery parts procurement
Zero welding hidden danger – Forged blank forming avoids weld cracking common on ordinary welded rims.
Dual-layer performance protection – Core toughness + surface hardness dual guarantee, anti-impact and anti-abrasion.
Low operation cost – Long service cycle reduces frequent rim replacement downtime for mine sites.

- Construction Earthmoving Heavy Machinery Large loaders, rigid haulers and other off-road heavy equipment replacement wheel rims.
Key Installation & Maintenance Guidance
Pre-Installation Check
Measure clearance between axle journal and hub bore strictly; never hammer forcibly to press the rim into position to avoid deformation.
Lubrication Standard
Only adopt lithium-based high-temperature grease; calcium-based grease is forbidden to prevent high-temperature carbonization and axle jamming.
Replacement Rules
New and old wheel rims must share identical specifications; central bore distance tolerance controlled within 1 mm.
Storage Requirements
Indoor dry storage is mandatory; outdoor stacking will lead to surface rust and structural deformation.
