This tungsten carbide (WC-Co) center bushing is custom developed for high-precision rotating machinery, grinding machines, lathes, and automated equipment. Manufactured using ultra-fine grain tungsten carbide matrix with a cobalt binder, and formed via isostatic pressing and precision sintering, it is specifically designed to withstand high rotational speeds, high impact loads, and severe abrasive conditions in center support and guidance applications. Fully customized solutions for non-standard dimensions, special shapes, and compound angles are available to meet your most demanding wear resistance and geometric accuracy requirements.
Key Advantages

Tungsten carbide hardness: HRA 89-93 (approx. 1400-2000 HV)
Provides 5 to 10 times longer wear life than traditional tool steels
Ideal for high-frequency start/stop operation and abrasive environments
Excellent Impact Resistance & Thermal Stability
Cobalt content customizable from 6% to 15%
Special grades available (non-magnetic, corrosion-resistant Ni-binder)
Coefficient of thermal expansion only 1/2 to 1/3 that of steel
High-Precision Custom Capabilities
Inner diameter tolerance down to IT4-IT5 (+0/-5μm)
Roundness and cylindricity ≤1.5μm
Available with lapping, mirror polishing (Ra ≤0.05μm) or DLC coating
