NSK Spherical Roller Stainless Steel Spherical 22320CAE4, Double row with Low Friction

NSK Spherical Roller Bearings 22320CAE4, Double row with Low Friction for Oil Drill and Stone Crusher

Spherical roller bearings have barrel-shaped rollers between the inner ring, which has two raceways, and the outer ring which has one spherical raceway. Since the center of curvature of the outer ring raceway surface coincides with the bearing axis, they are self-aligning in a manner similar to that of self-aligning ball bearings. Therefore, if there is deflection of the shaft or housing or misalignment of their axes, it is automatically corrected so excessive force is not applied to the bearings.
Spherical roller bearings can take, not only heavy radial loads, but also some axial loads in either direction. They have excellent radial load-carrying capacity and are suitable for use where there are heavy or impact loads.

Quick Detail:

With two structures of bore cylindrical or tapered and retainers made of steel sheet or syntheticresins, the bearings are characteristic of compensate concentricity and deflection errors.The bearings are available in open and sealed versions.Self-aligning ball bearings are for heavy load and shock load , precision instruments, low noise motors, automobiles, motorcycles, metallurgy, mill, mining, petroleum, paper, cement, sugar, and other common machinery.

Competitive Advantage:

1. Quality level: reach the same level as the Japanese and European bearings

2. Tolerance level: ABEC-1 (P0), ABEC-3 (P6)

3. Less coefficient of friction

4. High limiting speed

5. Large size range
