35mm Inner Diameter (ID): Fits small-to-medium industrial shafts (tolerance: 0/-0.015mm) and accommodates a minimum 2.2mm shaft chamfer. The tight tolerance ensures a secure H7/k6 interference fit with 6-12kW motor shafts, medium CNC spindle shafts, or large seeder drive rollers—preventing slippage even under torque surges (e.g., medium lathe cutting thick metal parts, heavy mixer stirring low-viscosity materials).
80mm Outer Diameter (OD): Seamlessly integrates into compact housings (compatible with a minimum 2.0mm outer ring chamfer), eliminating oversized enclosures. Critical for medium industrial pumps, compact gearboxes, or portable construction tools (e.g., medium drills) where space is limited.
22mm Width: Provides a 22% larger contact area than narrower bearings of similar ID/OD, ensuring balanced radial-axial load distribution. Ideal for medium vibrating screens (sorting 8-40mm granular materials) or auxiliary shafts in heavy agricultural machinery.
