The 32220 bearing uses a 100 mm bore and 180 mm outside diameter with a 49 mm overall assembly width. Its wider axial envelope distinguishes it from the 30220, which uses the same bore and outside diameter. Confirm all five principal dimensions before selecting a replacement.

Ratings and mass for the actual quoted configuration remain subject to factory confirmation. They are not ratings transferred from another bearing brand. Reference mass excludes packaging.
Single-Row Tapered Roller Bearing Features
The standard single-row tapered design accommodates combined radial load and axial load in one direction. The cone assembly and outer cup are separable. Loads in both axial directions require a suitable bearing arrangement; the complete design and setting must be reviewed for the application.
32220 Replacement and Selection Guide
The 30220 bearing, 100 x 180 x 37 mm, is 12 mm narrower than the 32220 and cannot be treated as the same fit. A 32320 tapered roller bearing has a 215 mm outside diameter and 77.5 mm assembly width, so it also requires a different installation envelope.
Check the full designation, matching cone and cup, shaft and housing abutments, lubrication requirements and the specified endplay or preload. Do not infer a precision class, cage material or operating-speed limit from the basic number. For an existing machine, follow the equipment manufacturer’s drawing and setting procedure.
Questions About 32220
Why is the 49 mm assembly width important?
The bearing must fit the available axial space and the specified shaft and housing arrangement. A 100 x 180 mm diameter match does not confirm a 32220 replacement; check the 49 mm total width, 46 mm inner-ring width and 39 mm outer-ring width.
Can I order an inner assembly for an existing outer cup?
Send the full markings from both components and the equipment drawing if available. Cone and cup compatibility must be confirmed for the supplied design; the same basic bearing number does not establish compatibility across different manufacturers or variants.
How do I request a 32220 bearing quotation?
Send the complete designation, quantity and delivery destination, together with any required tolerance, cage or matched arrangement. A drawing or clear photographs of the existing markings help identify special requirements. Availability, the supplied specification and delivery terms are confirmed with the quotation.
