80mm Inner Diameter (ID): Fits mid-size industrial shafts (tolerance: 0/-0.019mm) and accommodates a minimum 3.8mm shaft chamfer. The tight ID tolerance ensures a secure interference fit with 55-65kW motor shafts, heavy-duty CNC spindle shafts, or mid-size conveyor drive rollers—preventing slippage even under extreme torque surges (e.g., wheel loader bucket lifting with wet concrete, industrial pump startup under high backpressure).
130mm Outer Diameter (OD): Seamlessly integrates into mid-size machinery housings (compatible with a minimum 3.2mm outer ring chamfer), eliminating the need for oversized enclosures. This is critical for heavy-duty industrial lathes, high-pressure pumps, and agricultural equipment (e.g., large combine harvesters) where space constraints rule out bulkier bearing designs.
37mm Width: Maintains a compact profile while providing an expanded contact area (≈34% larger than narrower mid-size bearings of similar ID/OD) for balanced radial-axial load distribution. Unlike smaller 33115 models, the 33116 retains the 37mm width while increasing inner/outer diameters—boosting load-bearing capacity by 12-18% without requiring additional installation space. This makes it ideal for mid-size vibrating screens (for aggregate or mineral sorting), heavy-duty gearbox input/output shafts, or small rolling mill work rolls.
CNC grinding (with a precision of ±0.004mm) guarantees dimensional consistency across batches, eliminating fit gaps that cause 97-99% efficiency loss in misaligned mid-size heavy-duty bearings.
