4300 series size chart
Each row is one size and links to its model page. Dimensions are in millimetres.
4300 series
Dimensions are the same as on each model page. Models without a complete bore, OD and width are not listed here; ask us for them.
Selection checks
- Check the axial space first. A 43xx bearing is wider than the 63xx bearing of the same bore and OD.
- Both rows share one pair of rings, so shaft and housing alignment matters. Keep misalignment low.
- State the clearance you need in the order, together with the fits.
- Load ratings are on each model page. Compare them with the actual load before you choose.
Custom double-row bearings
We also make double-row bearings to drawing: special bores, widths, seals and clearance. Send d, D, B, seal type, clearance, speed, loads and quantity.
Frequently asked questions
Can a 43xx bearing replace a 63xx bearing?
Bore and OD are the same, but the 43xx is wider. It fits only if the shaft and housing have the axial space for the extra width.
What are the dimensions of a 4305 bearing?
A 4305 bearing is 25 × 62 × 24 mm (bore × OD × width).
Do you make these with seals?
Send the model and the seal type you need. We confirm the available version before quoting.
