Decoding SKF 3215 A-2RS1
- 32Series
- Double row angular contact ball bearings, 32 series. Series differ in outside diameter and width even when the bore is the same.
- 15Bore
- Bore 75 mm (15 × 5).
- A-2RS1Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3215 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3215 A-2RS1 measures 75 mm across the bore and 130 mm across the outside diameter; its width is 41.3 mm (75 x 130 x 41.3 mm).

When a shaft carries both radial and axial forces and there is little room for two separate bearings, a double row angular contact ball bearing from SKF is a practical choice. Two ball rows work in parallel inside one unit, so the design can handle loads in both directions without a second housing. Equipment such as pumps, gearboxes and machine tools often relies on this arrangement. MR Industrial Accessories supplies this line and helps you match the part number to your application.
Reading the designation makes selection easier. Take 3204 A-2RS1: the first two digits, 32, point to the medium-section double row series, while 04 is a bore code that does not translate directly into millimeters. The letter A marks an internal design variant, and 2RS1 means rubber seals on both sides. In 3306 A-2RS1, the 33 prefix indicates a wider section. Checking these characters is the fastest way to confirm what you are ordering.
These bearings are common in centrifugal pumps, speed reducers, compressors, industrial fans and machine tools. Because they take radial and axial loads at the same time, they suit shafts where both forces appear together. You will also find them in power transmission equipment such as gearboxes and conveyor systems. The double row construction gives more rigidity than a single row bearing, which supports steadier and quieter running in demanding service.
Selection should start with the radial and axial loads, the rotational speed and the operating environment. The 2RS1 seal keeps out dust and moisture, but at high temperatures or speeds an open bearing or one with metal shields may work better. During mounting, verify shaft and housing alignment and use the lubrication the manufacturer recommends. Poor fitting leads to noise, vibration and early wear. If anything is unclear, send us your application data.
SKF bearings interchange with other brands that share the same standardized dimensions. For a replacement, compare the complete part number rather than only the basic number, since a seal or internal clearance variant changes performance. Letters after the basic number indicate design differences, so two bearings with the same four digits are not always the same. If you need an equivalent, send the original part number and we will help you find the right option in our bearing line.

Frequently asked questions
- SKF 3215 A-2RS1 bearing: what are its dimensions?
- SKF 3215 A-2RS1 measures 75 mm across the bore and 130 mm across the outside diameter; its width is 41.3 mm (75 x 130 x 41.3 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3215.
- What does the 2RS1 suffix mean on these bearings?
- It shows that the bearing has rubber seals on both sides. These seals keep out dust, water and other contaminants and hold lubrication in place. They suit moderately dirty environments, though they add friction and reduce the maximum speed compared with open designs.
- How do I know if a double row bearing replaces two single row ones?
- There is no direct equivalence. A double row bearing fits one housing and takes loads in both directions, while two single row bearings may need a specific arrangement. Check dimensions and load capacities, or send us your equipment data and we will advise you.
- Can I use these bearings at high speeds?
- The permissible speed depends on design, lubrication and load. Bearings with 2RS1 seals usually have a lower limit than open ones because of seal friction. For high revolutions, review the operating conditions and pick the appropriate variant. Consult us with your equipment parameters.
