BEARING SPECIFICATION / 22308
40 × 90 × 33 mm · Heavy radial duty with alignment flexibility. Compare the sourced reference data and specify your SANJ requirement.

Spherical Roller Bearings
22308 identifies a spherical roller bearing reference with 40 mm bore, 90 mm outside diameter and 33 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.
REFERENCE SPECIFICATION
Full factual values from the source designation 22308RZ. Mounting dimensions and reference mass relate to that design; they must be checked against the final SANJ drawing.

SELECTION CONTEXT
22308 belongs to the spherical roller bearings family. Its reference envelope is 40 mm bore, 90 mm outside diameter and 33 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.
No. Matching 40 × 90 × 33 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
