45mm Inner Diameter (ID): Fits small-to-medium industrial shafts (tolerance: 0/-0.018mm) and accommodates a minimum 3.0mm shaft chamfer. The tight ID tolerance ensures a secure interference fit (H7/k6 fit) with 15-20kW motor shafts, industrial CNC spindle shafts, or large seeder drive rollers—preventing slippage even under torque surges (e.g., lathe cutting thick metal, mixer stirring high-viscosity materials).
85mm Outer Diameter (OD): Seamlessly integrates into mid-sized compact housings (compatible with a minimum 2.5mm outer ring chamfer), eliminating oversized enclosures. Critical for heavy industrial pumps, mid-sized gearboxes, or portable construction tools where space is limited.
32mm Width: Maintains a compact profile while providing a 30% larger contact area than narrower bearings of similar ID/OD, ensuring balanced radial-axial load distribution. Ideal for industrial vibrating screens (for 10-60mm granular sorting) or auxiliary shafts in heavy agricultural machinery.
