How to read SKF 2317
- 23Series
- Self-aligning ball bearings, 23 series. For the same bore, each series has a different outside diameter and width.
- 17Bore
- 85 mm bore: 17 × 5.
2317 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 2317 bearing has a 85 mm bore, a 180 mm outside diameter and a 60 mm width (85 x 180 x 60 mm).

The self-aligning ball bearing has two rows of balls with a common spherical outer raceway, which allows it to absorb angular misalignment between the shaft and the housing —due to shaft deflection or mounting error— without transmitting that misalignment as extra load to the balls.
The designation is a four-digit number that identifies the size; unlike the spherical roller bearing, it usually does not carry sealing suffixes in the smaller sizes, although sealed variants of larger diameter are also found on the market.
It is used on long shafts that may deflect under load, in equipment where exact alignment between the shaft and the support is difficult to guarantee, and in applications where tolerating misalignment is prioritized over maximum load capacity, which is lower than that of a deep groove ball bearing of the same size.
Because of its lower load capacity relative to its size, it is not the first choice when shaft alignment is guaranteed: in those cases, a deep groove ball bearing or a cylindrical roller bearing of the same size performs better. The advantage of the self-aligning bearing appears specifically when there is real misalignment to absorb.
The size of this series is standardized by bore, outside diameter and width among the main bearing manufacturers, so an equivalent from other brands is usually available for the same size.

Frequently Asked Questions
- What are the dimensions of the SKF 2317 bearing?
- The SKF 2317 bearing has a 85 mm bore, a 180 mm outside diameter and a 60 mm width (85 x 180 x 60 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2317.
- When is a self-aligning ball bearing preferable to a rigid one?
- When there is real misalignment between the shaft and the housing, due to shaft deflection or mounting difficulty. If alignment is guaranteed, a deep groove ball bearing of the same size performs better.
- Why does it have less load capacity than a deep groove ball bearing?
- Because its geometry prioritizes the ability to absorb angular misalignment, which somewhat reduces radial load capacity compared with a rigid design of the same size.
- Are there sealed versions of this bearing?
- In the larger sizes, sealed variants are indeed available. Tell us the diameter and we will confirm which options there are.
