Dimensions
The principal dimensions of SKF 6003-2RSH are:
d - Bore Diameter: 17 mm
D - Outside Diameter: 35 mm
B - Width: 10 mm
Commercial Size: 17x35x10 mm
For this bearing, 17x35x10 mm corresponds to d x D x B.
The bore code 03 corresponds to a nominal bore diameter of 17 mm.
Bearing Construction
SKF 6003-2RSH is a single-row deep groove ball bearing with a non-separable construction.
The balls operate between deep raceway grooves in the inner and outer rings. This geometry is primarily intended for radial loading but also enables the bearing to support axial loads in both directions.
The exact configuration uses a cylindrical bore, sheet-metal cage and grease lubrication.
2RSH Contact Seals
The 2RSH suffix identifies the sealing arrangement.
For SKF 6003-2RSH, the bearing has contact seals on both sides.
The seals help retain grease within the bearing and reduce the ingress of contaminants into the rolling contact area.
This differs from the 6003-2Z version, which uses metal shields rather than contact seals. Identical principal dimensions do not make these versions technically identical.
CN Radial Internal Clearance
The standard SKF 6003-2RSH uses CN radial internal clearance, meaning the Normal clearance group.
This is important when comparing it with:
SKF 6003-2RSH/C3
The C3 version has greater-than-Normal radial internal clearance and should be treated as a separate product configuration.
Therefore:
6003-2RSH ≠ 6003-2RSH/C3
even though both bearings share the same 17x35x10 mm dimensions and sealing arrangement.
Load Ratings and Operating Principle
For SKF 6003-2RSH, the verified catalogue ratings are:
C - Basic Dynamic Load Rating: 6.37 kN
C0 - Basic Static Load Rating: 3.25 kN
Pu - Fatigue Load Limit: 0.137 kN
The deep groove raceway geometry enables the bearing to carry radial loads and axial loads acting in both directions.
These catalogue ratings are engineering parameters used in bearing calculations. They should not be interpreted as simple maximum permissible machine loads.
Limiting Speed
The specified limiting speed is 13,000 r/min.
Actual permissible operating speed in a specific bearing arrangement depends on factors such as load, fits, temperature, lubrication and surrounding components.
The speed value should therefore be treated as a catalogue parameter rather than a universal operating recommendation.
Meaning of 6003-2RSH
The complete designation can be interpreted as:
6 - deep groove ball bearing
60 - dimensional series
03 - bore code corresponding to 17 mm
2RSH - contact seals on both sides
Because the product does not include a C3 suffix, the standard version should not be described as a C3 bearing.
SKF 6003-2RSH vs 6003-2RSH/C3
Both variants have:
d = 17 mm
D = 35 mm
B = 10 mm
contact seals on both sides
The key difference is radial internal clearance:
6003-2RSH: CN / Normal clearance
6003-2RSH/C3: C3 / greater-than-Normal clearance
The two variants should therefore remain separate product pages.
SKF 6003-2RSH vs W 6003-2RS1
The W prefix changes the product identity.
W 6003-2RS1 is a stainless steel SKF bearing, whereas 6003-2RSH is the standard bearing-steel version.
Although both may have the same principal dimensions of 17x35x10 mm, they are different products with different material construction and technical data.
Selection and Interchangeability
When selecting a replacement for SKF 6003-2RSH, compare:
- complete bearing designation,
- single-row deep groove construction,
- d = 17 mm,
- D = 35 mm,
- B = 10 mm,
- contact seals on both sides,
- CN radial internal clearance,
- dynamic and static load ratings,
- speed requirements,
- shaft and housing fits,
- lubrication,
- operating temperature and environment.
A bearing described only as 6003 2RS 17x35x10 from another manufacturer is not automatically confirmed as a complete technical equivalent.
