Deep Groove Ball Bearings SKF 6004 -2Z

The SKF 6004-2Z deep-groove ball bearing features compact dimensions of 20x42x12 mm and cover plates on both sides to protect against dirt particles.

This single-row deep-groove ball bearing 6004 -2Z is designed for predominantly radial loads as well as moderate axial forces in both directions. The Explorer series design combines optimised surfaces with high material purity from standard rolling-bearing steel (100Cr6). Thanks to the non-contact sheet metal shields on both sides, this rolling bearing is suitable for operating environments where lubricant loss and the ingress of dust particles need to be prevented.

Under what operating conditions does the 6004-2Z deep-groove ball bearing operate?

The bearing is suitable for rotating systems subject to predominantly radial loads and moderate axial forces at high speeds. Thanks to the low friction of the non-contact gap seal, the design enables low-friction rotational movement whilst providing basic protection against solid contaminants. The permissible temperature range extends from –20 to +120 degrees Celsius, meaning the rolling bearing can be used in a variety of industrial temperature ranges.

What do the P6 and P5 tolerances mean for this model?

This model has tighter manufacturing tolerances: the dimensional accuracy corresponds to class P6, whilst the running accuracy is manufactured to class P5. In practice, this reduced runout deviation contributes to smooth running and low vibration during operation. Users specifically choose this version when precise shaft guidance is required and a sheet steel cage is needed to maintain a stable clearance between the rolling elements.
