Spherical roller bearing (Self-aligning roller bearing)

Spherical roller bearing has two rows of spherical rollers between the sphered raceway in the outer ring and two inner rings raceways inclined at an angle to the bearing axis. Due to the arc center of the raceways in the outer ring and the bearing center are in the same direction, as a result, shaft flexing and misalignment of the bearing seats are compensated. Spherical roller bearing can support axial forces in both directions and high radial forces. They are designed for very high load carrying capacity. Bearings with a tapered bore are also available with an adapter sleeve, locknut and tab washer or with a withdrawal sleeve. When shaft bends by force which causes the inclined between the center of inner ring and the center of outer ring, if the inclined degree not exceed 1-2.5,the bearing can work normally.

 Applications:

•Excellent alignment compensation

•Suitable for large radial loads

•Low to medium speed ratings

•Application examples: heavy machinery (e.g. construction and mining machines), rolling mills, gear boxes, shaker screens, etc.

  • Reduced friction torque (as much as 30% less), offering lower operating temperature, with lower power and lubricant consumption.
  • Appreciably increased operating speed, allowing an extended scope of applications.
  • High temperature capacity of up to 200°C (392°F) for metallic cage bearings. Dimensional stability is ensured by a specific heat treatment.
  • A +/- 0.5° misalignment capability, without reducing the load capacity, and up to 1° 30’ in case of low loads.
