Deep Groove Ball Bearings SKF 6004

The SKF 6004 deep groove ball bearing is an open rolling bearing measuring 20 × 42 × 12 mm, designed for radial loads in clean operating environments.

The 6004 deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with a bore of 20 mm, an outside diameter of 42 mm and a width of 12 mm. SKF manufactures this version in the Explorer class. The bearing has a sheet steel cage and operates with standard radial clearance. Due to its open design without integrated sealing washers, this model is particularly suitable for oil-lubricated systems or clean installation environments in industry and trade.

What is the 6004 deep groove ball bearing suitable for in industrial applications?

This ball bearing primarily accommodates radial forces as well as axial loads in both directions. As the manufacturer has omitted contact seals, the component runs smoothly and is suitable for higher speeds than sealed versions. Typical applications include bearing arrangements with external sealing and lubrication. As no grease is pre-filled at the factory, the lubricant can be flexibly selected to suit the overall system.

What do the tolerance classes P6 and P5 mean for the 6004 deep groove ball bearing?

In this model, SKF combines dimensional accuracy to class P6 with finer running accuracy to class P5. Compared with standard bearing tolerances, this results in reduced runout errors and lower dimensional variations in the inner and outer rings. In terms of design, this supports low-vibration operation and reduced noise levels. When specifying the bearing, the permissible temperature range of -20 to +120 degrees and the need for external protection against dirt particles must be taken into account.
