SKF 6001-2RS1 is a single-row deep groove ball bearing measuring 12x28x8 mm. It has a 12 mm bore diameter, 28 mm outside diameter and 8 mm width. The 2RS1 configuration has seals on both sides, distinguishing this bearing from open and shielded 6001 variants.
SKF 6001-2RS1 - Product Characteristics
SKF 6001-2RS1 belongs to the 6000 series of single-row deep groove ball bearings.
The principal verified data are:
Manufacturer / Brand: SKF

Width B: 8 mm
Sealing: Both sides
Basic Dynamic Load Rating C: 5.4 kN

SKF documentation confirms the 12x28x8 mm dimensions and catalogue load ratings for the standard 6001 bearing size.
Dimensions
The principal dimensions of SKF 6001-2RS1 are:
d - Bore Diameter: 12 mm
D - Outside Diameter: 28 mm
B - Width: 8 mm
Commercial Size: 12x28x8 mm
For this bearing, the dimensional notation 12x28x8 mm corresponds to d x D x B.
The 01 bore code is a standardized exception to the general x5 bore-code rule used from code 04 upward. For deep groove ball bearings, code 01 corresponds to a 12 mm bore.
Bearing Construction
SKF 6001-2RS1 is a single-row deep groove ball bearing.
The rolling elements are balls running between deep raceway grooves in the inner and outer rings. This raceway geometry is primarily designed for radial loads but also allows the bearing to accommodate axial loads acting in both directions.
The basic construction is non-separable.
This combination of radial and bidirectional axial load capability is a characteristic of the deep groove ball bearing design and should be distinguished from bearing types designed for primarily axial or direction-specific loading.
2RS1 Sealing
The 2RS1 suffix identifies a bearing equipped with seals on both sides.
The seals help retain lubricant within the bearing and restrict the ingress of contaminants into the rolling contact area.
Within the same 6001 dimensional size, different closure configurations can exist:
6001 - open bearing
6001-2RS1 - sealed on both sides
6001-2Z - shielded on both sides
These configurations may share the same 12x28x8 mm principal dimensions but should not automatically be treated as technically identical.
Load Ratings and Operating Principle
SKF catalogue data for the standard 6001 bearing size specify:
C - Basic Dynamic Load Rating: 5.4 kN
C0 - Basic Static Load Rating: 2.36 kN
Pu - Fatigue Load Limit: 0.10 kN.
The deep groove raceway geometry allows the bearing to support radial loads and axial loads acting in both directions.
The catalogue values C, C0 and Pu are engineering parameters used in bearing selection and calculation. They should not be interpreted as simple maximum permissible machine loads.
Actual bearing selection should consider load magnitude and direction, required rating life, rotational speed, shaft and housing fits, internal clearance, lubrication, temperature and environmental conditions.
Meaning of 6001-2RS1
The designation provides information about the bearing configuration:
6 - deep groove ball bearing
60 - dimensional series
01 - bore code corresponding to 12 mm
2RS1 - seals on both sides
The commercial description SKF 6001 2RS is commonly used in the bearing market, but SKF 6001-2RS1 provides more precise identification when this suffix is present on the bearing or original SKF packaging.
6001-2RS1 vs 6001-2RSH
This distinction is worth checking when identifying current SKF stock.
SKF documentation and distribution channels contain both 6001-2RS1 and 6001-2RSH designations. Current SKF tables can list 6001-2RSH for the sealed standard-steel configuration, while 6001-2RS1 remains identifiable in SKF product data.
For this reason, 2RS1 and 2RSH should not be silently rewritten as one another on a technical product page.
If the physical bearing or original SKF box is marked 6001-2RS1, retain 6001-2RS1. If it is marked 6001-2RSH, the product page should use 6001-2RSH.
SKF 6001-2RS1 vs W 6001-2RS1
The prefix W changes the product identity.
SKF W 6001-2RS1 is a stainless steel deep groove ball bearing. Although it also has principal dimensions of 12x28x8 mm, SKF specifies different load ratings for the stainless steel version.
Therefore:
6001-2RS1 ≠ W 6001-2RS1
The W prefix must not be added or removed merely because the bearings share the same dimensions.
Selection and Interchangeability
When selecting a replacement for SKF 6001-2RS1, compare:
- complete bearing designation,
- deep groove ball bearing construction,
- d = 12 mm,
- D = 28 mm,
- B = 8 mm,
- sealing arrangement,
- radial internal clearance,
- dynamic and static load ratings,
- speed requirements,
- shaft and housing fits,
- lubrication,
- operating temperature and environment.
A bearing described simply as 6001 2RS 12x28x8 from another manufacturer is not automatically confirmed as a complete technical equivalent.
The dimensions are only one part of the replacement criteria.

FAQ
What are the dimensions of SKF 6001-2RS1?
SKF 6001-2RS1 measures 12x28x8 mm: d = 12 mm bore diameter, D = 28 mm outside diameter and B = 8 mm width.
What type of bearing is SKF 6001-2RS1?
It is a single-row deep groove ball bearing.
What does 2RS1 mean on SKF 6001-2RS1?
2RS1 identifies the configuration with seals on both sides of the bearing.
What does 01 mean in the 6001 designation?
The 01 bore code corresponds to a 12 mm bore diameter. It is one of the standardized small-bore exceptions to the x5 bore-code rule.
What are the load ratings of SKF 6001?
SKF catalogue data for the standard 6001 size specify C = 5.4 kN, C0 = 2.36 kN and Pu = 0.10 kN.
Can SKF 6001-2RS1 carry axial loads?
Yes. Its deep groove raceway geometry allows it to accommodate axial loads in both directions in addition to radial loads.
Is 6001-2RS1 the same as 6001-2RSH?
They should not automatically be treated as the same suffix. Both designations occur for SKF sealed 6001 bearings, and the exact marking on the bearing or original SKF packaging should be retained.
Can another 6001 2RS 12x28x8 bearing replace SKF 6001-2RS1?
Not automatically. The sealing configuration, internal clearance, load ratings, speed requirements, fits and operating conditions should also be compared.
