How is size determined for roller bearings?
How is size determined for roller bearings?
How Bearings Are Sized. Bearings are measured by their inner diameter, outer diameter, and width; the size of a bearing is normally listed as such: ID x OD x W. These measurements are normally taken in millimeters, but can be converted to inches.
What are the sizes of bearings?
Table 1 – Standard Bearing Sizes
| Basic # | Bore | OD Ball |
|---|---|---|
| R12 | .7500 | 1.6250 |
| R14 | .8750 | 1.8750 |
| R16 | 1.0000 | 2.0000 |
| R20 | 1.2500 | 2.2500 |
How do you determine bearing size from bearing number?
Note : In case there is no fourth digit, then the 3rd digit indicates the bore size in mm. For example: in case of bearing 636, the bore size of the bearing will be 6mm. Thus, we can identify now that in case of bearing 6305ZZ, the third and fourth digit ’05’ means the bearing’s bore size is 25 mm.
How are metric bearings measured?
Imperial bearings are measured in inches whilst metric bearings are measured in millimetres. One way to determine whether you have an imperial or metric bearing is to measure it. Most bearing sizes will be a full mm or inch measurement. So, if your bearing is metric, the measurement will be a full mm, for example 9mm.
What is metric bearing?
The metric series bearings are single or double row ball bearings available from 1 mm to 110 mm bore sizes. The construction of these bearings enable them to carry moderate radial and thrust loads at low operating torque and provide high performance.
What does M stand for in bearings?
Other suffixes from various brands
| Meaning | SKF | NSK |
|---|---|---|
| Solid brass cage, guided by rolling elements | M | MR |
| Bearing with snap ring groove in the outer ring of the bearing | N | N |
| Polymer cage | T | T |
| Pressed steel cage, one-piece | J | W |
What are metric bearings?
These metric bearings are radial, single-row bearings in chrome steel, stainless steel, and more. We also supply super precision ball bearings in metric sizes.
What are the different bearing sizes?

What is the part numbering system for tapered roller bearings?
The original metric part-numbering system for tapered roller bearings was based on the ISO 15 dimensional plan for radial bearings. ISO introduced a new numbering system for tapered roller bearings in the ISO 355 plan. This numbering system uses three alphanumeric fields to define a dimension series.
