Configuration and Use Notes
- Tapered-bore versions may use K after the bearing number. Availability and suffix conventions must be confirmed for the selected manufacturer.
- Oil, grease, and thermal reference speeds are design references, not universal application limits. Fit, clearance, load, temperature, lubrication, and surrounding components can reduce the permissible operating speed.
- Clearance classes and cage suffixes vary by manufacturer. Confirm the complete marking rather than selecting from the base model alone.
- Ratings, speeds, cage references, mounting data, and calculation factors are reference values for the listed design. Manufacturers and internal designs can differ even when boundary dimensions match. Confirm the selected brand, full suffix, clearance, and application before ordering.
What to Confirm Before Ordering
- Match the complete 22318 designation, including every suffix and bore marking.
- Confirm clearance, cage, lubrication features, shaft and housing fits, shoulders, fillets, speed, load, and temperature.
- Include the bearing position, current model or photo, quantity, destination, and required inspection or compliance files.
Common Applications
- Mining crushers
- Vibrating screens
- Heavy fans
- Industrial machinery
