SKF 6004-2RSH/C3 is a single-row deep groove ball bearing with 20 mm bore, 42 mm outside diameter and 12 mm width. The 2RSH suffix identifies RSH contact seals on both sides, while C3 identifies internal clearance greater than Normal. This complete designation should be retained when selecting a replacement because dimensions alone do not define sealing or clearance.
The 6004-2RSH/C3 belongs to the SKF deep groove ball bearing family. Its deep raceway geometry is designed primarily for radial loads while also allowing the bearing to accommodate axial loads in both directions.
For this product, the technically important features are the 6004 geometry, double RSH sealing and C3 internal clearance.
SKF catalogue dimensions are:
d - Bore Diameter: 20 mm
D - Outside Diameter: 42 mm
B - Width: 12 mm
The complete boundary dimensions are therefore 20x42x12 mm. For this bearing type, the third dimension corresponds to width B.
SKF 6004-2RSH/C3 is a single-row deep groove ball bearing. The balls run in deep raceway grooves formed in the inner and outer rings.
This geometry provides radial load capacity and axial guidance in both directions. The sealed design also helps protect the rolling elements and raceways from external contamination while retaining grease inside the bearing.
For the SKF 6004 design, catalogue values include:
Basic Dynamic Load Rating C: 9.95 kN
Basic Static Load Rating C0: 5.00 kN
Fatigue Load Limit Pu: 0.212 kN
These values are used in bearing selection and life calculations but should not be interpreted as direct permissible operating loads without considering actual load, speed, fits, temperature, lubrication and required service life.
2RSH means the bearing is fitted with RSH contact seals on both sides.
C3 means the bearing has internal clearance greater than Normal. This can be important where interference fits or thermal effects reduce operating clearance after installation.
A 6004-2RSH bearing with Normal clearance should therefore not automatically replace a specified 6004-2RSH/C3.
When selecting an equivalent for SKF 6004-2RSH/C3, compare at least:
Bearing type: single-row deep groove ball bearing
Dimensions: 20x42x12 mm
Sealing: contact seals on both sides
Internal clearance: C3
Load ratings: suitable for the application
Speed capability: suitable for the operating conditions
A 6004-2Z/C3 has the same basic dimensions and C3 clearance but uses metal shields instead of RSH contact seals. It should not automatically be considered fully interchangeable. SKF catalogues these as separate variants.
Manufacturer: SKF
Catalogue Designation: 6004-2RSH/C3
Type: Single-row deep groove ball bearing
Bore Diameter d: 20 mm
Outside Diameter D: 42 mm
Width B: 12 mm
Dimensions: 20x42x12 mm
Sealing: RSH contact seals on both sides
Internal Clearance: C3, greater than Normal
Basic Dynamic Load Rating C: 9.95 kN
Basic Static Load Rating C0: 5.00 kN
Fatigue Load Limit Pu: 0.212 kN
Load Direction: Radial and axial in both directions
The bearing measures 20x42x12 mm: d = 20 mm, D = 42 mm and B = 12 mm.
C3 means internal bearing clearance greater than Normal. The specified clearance class should be retained unless the application is re-evaluated.
2RSH means RSH contact seals are fitted on both sides of the bearing.
It is a single-row deep groove ball bearing designed mainly for radial loads while also accommodating axial loads in both directions.
Not automatically. Both may share the 20x42x12 mm dimensions and C3 clearance, but 2Z uses metal shields whereas 2RSH uses contact seals. The sealing system must match the operating environment.
Not automatically. The C3 variant has greater internal clearance, which can affect operating clearance after mounting and during temperature changes.
SKF 6004-2RSH/C3 is a single-row deep groove ball bearing measuring 20x42x12 mm, with RSH contact seals on both sides and C3 internal clearance greater than Normal. SKF specifies a basic dynamic load rating of 9.95 kN, static load rating of 5.00 kN and fatigue load limit of 0.212 kN.
