Deep Groove Ball Bearings SKF 6003 -2Z

The SKF 6003-2Z deep groove ball bearing features compact dimensions of 17x35x10 mm and non-contact end shields on both sides for reliable operation.

This single-row deep-groove ball bearing 6003-2Z primarily transmits radial forces and also accommodates axial loads in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel in the SKF Explorer design, the component is characterised by dimensional accuracy to P6 and running accuracy to P5. A sheet steel cage guides the rolling elements evenly into the deep raceways of the outer and inner rings, which have no flange or groove.

What is the 6003-2Z deep groove ball bearing suitable for in operation?

Designs subject to combined radial and axial loads, as well as those with limited installation space, utilise this rolling bearing due to its precise running characteristics. The combination of standard radial clearance and increased precision ensures that the bearing operates with low noise and vibration levels. The two non-contacting sheet metal cover plates keep out coarse dirt and dust particles whilst retaining the lubricant within the bearing chamber. This version is ready for direct installation in applications with operating temperatures ranging from –20 to +120 degrees.

What are the advantages of the cover plates and the P6/P5 tolerance class?

Compared to abrasive seals, the metal cover plates do not generate any additional frictional torque, meaning the bearing remains suitable for high speeds. The tight manufacturing tolerances – P6 for dimensions and P5 for concentricity – support precisely guided shafts. When designing the housing and shaft, please take into account the dimensions of a 17 mm bore, 35 mm outer diameter and 10 mm width.
