Overview
The 2312 is a double row self-aligning ball bearing with a 60 mm bore, 130 mm outer diameter and 46 mm width. Its two ball rows run in a common spherical outer raceway, so the bearing absorbs shaft deflection and housing misalignment instead of transferring it to the shaft or seals. It is dimensionally interchangeable with other 2312 bearings made to ISO 15.
Where the 2300 series fits
The 2300 series is a widest-section series. It keeps the bore diameter of the corresponding size while changing the outer ring section, so it suits layouts where radial capacity or housing space rules out the neighbouring series. Compared with the 1200 series at the same bore, the 2200 series carries a wider section and higher radial capacity.
Typical applications
- Industrial fans and blowers
- Conveyor pulleys and line shafting
- Textile and woodworking machinery
- Agricultural implements
- Light gearboxes where shaft deflection is expected

Frequently asked questions
What are the dimensions of a 2312 bearing?
A 2312 self-aligning ball bearing has a 60 mm bore, 130 mm outer diameter and 46 mm width.
Can I replace a 2312 with another brand’s 2312?
Yes, dimensionally. The envelope is fixed by ISO 15, so any 2312 mounts on the same shaft and housing. Cage material, clearance and precision grade may differ and should be confirmed for the application.
