Spherical Roller Bearings

22218 at a glance

22218 identifies a spherical roller bearing reference with 90 mm bore, 160 mm outside diameter and 40 mm overall width or height.

Bore / d: 90 mm
Outside / D: 160 mm
Width / B: 40 mm

Two rows of spherical rollers accommodate angular misalignment within the selected design limits. Bore type, clearance and mounting method matter.

SELECTION CONTEXT

Match the bearing
to its duty.

22218 belongs to the spherical roller bearings family. Its reference envelope is 90 mm bore, 160 mm outside diameter and 40 mm overall width or height.

Two rows of spherical rollers accommodate angular misalignment within the selected design limits. Bore type, clearance and mounting method matter.

For a manufacturing enquiry, provide the complete designation and operating conditions. Matching the dimensional envelope alone does not confirm interchangeability or equivalent performance.

Is the same size a direct replacement?

No. Matching 90 × 160 × 40 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
