Suffix “X” Meaning:
1) Special-feature bearing — not interchangeable with bearings that share the same basic part number.
2) ISO bearing — matches the basic part number’s external dimensions but uses different internal geometry to provide higher load ratings.

Installation Best Practices:

1. Check parts and cleanliness: inspect cone, cup, rollers and seating surfaces for damage or debris; work in a clean area and wear gloves.
2. Confirm dimensions and fits: verify shaft/housing tolerances and mounting fits per spec (press-fit vs slip-fit).
3. Press the cone onto the shaft: apply force only to the ring being fitted (use a bearing press or arbor); do not hit the rollers or cage.
4. Use correct heating/cooling if needed: heat the housing (not exceeding recommended temp) or chill the cone to ease interference fits.
5. Align and seat evenly: ensure the cone and cup sit flush and concentric; avoid tilting during assembly.
6. Set preload or clearance correctly: adjust axial position or use paired bearings to obtain required preload/clearance per application.
7. Secure locking devices: tighten nuts, lockrings or set screws to specified torque values.
8. Lubricate appropriately: apply recommended grease or oil amount and type before operation.
9. Test rotation and check for issues: rotate by hand to confirm smooth movement, no binding or unusual noise; recheck axial play and alignment after initial run-in.
