Core Advantages
Precision Machined Replacement Installation Dimensions
Outer diameter, spindle size and mounting bracket dimensions are precisely processed for perfect fit. Direct bolt-on replacement requires no cutting or secondary modification.
Deep Hardened Wheel Surface
The wheel body undergoes carburizing heat treatment to achieve high surface hardness, extending service life significantly in rocky open-pit mining environments.
Thickened Forged Shaft & Premium Double Oil Seal Assembly
Equipped with heavy-duty built-in bearings and dual leak-proof oil seal structure, it prevents grease leakage and prolongs lubrication intervals to cut down maintenance frequency.
