Product Features
- Wide inner ring design provides effective shaft support for a broad range of industrial applications.
- Spherical outer diameter compensates for shaft misalignment in mounted bearing housings.
- Set screw locking mechanism secures the bearing to the shaft, ideal for reversing load applications.
- Double RSR seals on both sides protect against contaminants and retain lubricant.
- Relubricatable via lubrication hole with grease fitting for extended service life.
- Premium chrome steel (52100) construction with super-finished raceways and grade 10 balls for smooth, low-noise operation.
Installation Notes
- This insert bearing is designed for use in customer-supplied housings with corresponding spherical inside surfaces.
- Before installation, clean the shaft and housing bore thoroughly and inspect for damage or wear.
- Tighten set screws to the manufacturer’s specified torque – over-tightening can distort the bearing inner ring.
- Relubricate through the grease fitting after installation to ensure proper lubrication.
- We recommend professional installation to verify fitment and ensure correct shaft alignment.
