Engineered to ISO 355/DIN 720 standards with P6-level precision (tolerance class for minimal vibration and misalignment), the dimensions are optimized for mid-to-large heavy-duty setups where space is limited but load demands are high:
120mm Inner Diameter (ID): Fits extra-large industrial shafts (tolerance: 0/-0.018mm) and accommodates a minimum 3.5mm shaft chamfer. The tight ID tolerance ensures a secure interference fit with 45-55kW motor shafts, heavy CNC spindle shafts, or mining conveyor drive rollers—preventing slippage even under extreme torque surges (e.g., during bulldozer blade lifting).
180mm Outer Diameter (OD): Seamlessly integrates into mid-to-large machinery housings (compatible with a minimum 3mm outer ring chamfer), eliminating the need for oversized enclosures. This is critical for large lathes, industrial water pumps, and medium mining equipment (e.g., small ore crushers, coal conveyors) where space constraints prevent the use of bulkier heavy-duty bearings.
48mm Width: Provides an enhanced contact area (≈25% larger than narrower bearings of similar ID/OD) for radial-axial load distribution while avoiding space waste. This makes it ideal for tight setups like industrial vibrating screens (for mineral processing), heavy-duty gearbox input shafts, or rolling mill auxiliary components.
CNC grinding (with a precision of ±0.004mm) guarantees dimensional consistency across batches, eliminating fit gaps that cause 95-99% efficiency loss in misaligned mid-to-large heavy-duty bearings.
