Frequently asked questions

What does the "C3" suffix mean on the SKF 6228/C3?
C3 denotes a greater-than-normal internal radial clearance. It is recommended when the bearing will operate at higher temperatures, under interference fits, or in applications where thermal expansion is a concern.

Is SKF 6228/C3 the same as 6228 C3?
Yes. The designations SKF 6228/C3, 6228 C3, and 6228C3 all refer to the same bearing. The slash or space before C3 is a formatting convention only.

Can I replace an existing 6228 (CN clearance) with a 6228/C3?
The external dimensions are identical. Switching to C3 is common in high-speed or high-temperature installations. Consult your application requirements before substituting.
