The 32320 bearing has a larger installation envelope than the 30220 and 32220 despite sharing their 100 mm bore. Its 215 mm outside diameter and 77.5 mm assembly width must both be checked against the housing and available axial space.

Data status: The load ratings and reference mass above are transcribed from the supplied ZQM catalogue, page 110. 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.
32320 Replacement and Selection Guide
Compared with the 30220 bearing and 32220 bearing, the 32320 outside diameter is 35 mm larger. Its assembly width is 40.5 mm greater than the 30220 and 28.5 mm greater than the 32220. These are dimensional differences, not evidence of interchangeable fits or a guaranteed load-capacity advantage.
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 32320
Is a 32320 interchangeable with other 100 mm bore bearings?
A shared bore diameter is not sufficient. The 32320 requires a 215 mm housing diameter and 77.5 mm assembly width, compared with 180 mm outside diameter and 37 or 49 mm assembly width for the 30220 and 32220.
What should be checked beyond the main dimensions?
Review the complete designation, cone and cup compatibility, shaft and housing abutments, corner radii and required bearing setting against the equipment and supplier drawings. Principal dimensions alone do not establish application suitability.
How do I request a 32320 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.
