Search the QCB Database by Dimension
We’ve tried to make this as easy as possible…
- Select the correct gear style (i.e. ungeared, external or internal gear) in the SEARCH bar under the column heading
- If you have a geared bearing then select the number of teeth
- If you have an ungeared bearing select the external diameter in mm
- The database will filter out the QCB parts that fit these criteria and if possible provide a link to relevant drawings
These tables offer the QCB catalogue range only, but our database is far more extensive. If you do not see your bearing here, call us for immediate assistance!
Or download some helpful “Identification Drawings”
If you cannot find your bearing in the tables above, we may still know it by another reference.
If you can measure it up, download the “identification drawings” below, select the right cross section and fill in as much information as you can and submit to our technical team for further analysis..
Any information on where it is fitted, photos of the bearing and any identification marks will help us help you!
