Deep Groove Ball Bearings SKF 6005 -2Z

The SKF 6005-2Z deep groove ball bearing, measuring 25x47x12 mm and featuring cover plates on both sides, provides protection against dirt particles.

This single-row deep groove ball bearing 6005 -2Z from SKF is designed for predominantly radial loads as well as moderate axial forces in both directions. Thanks to its standardised main dimensions – a bore diameter of 25 mm, an outside diameter of 47 mm and a width of 12 mm – the roller bearing fits precisely into structural assemblies. In the SKF Explorer version, the bearing is made from pure 100Cr6 bearing steel, which is used for both the raceways and the rolling elements. A robust sheet-steel cage guides the row of balls evenly within the cylindrical outer ring, which has no flange or ring groove.

What operating conditions does the 6005-2Z deep groove ball bearing require?

Compact installation spaces and speed requirements determine the use of this deep groove ball bearing in rotating shaft systems. As the bearing is fitted with non-contact cover plates on both sides, it is suitable for clean to moderately dusty operating environments where minimal frictional heat is required. The permissible temperature range extends from –20 to +120 degrees Celsius, meaning the rolling bearing can be used in a variety of thermal operating conditions.

What features do the cover plates and tolerance classes offer in the 6005-2Z?

The suffix -2Z refers to the sheet metal covers integrated on both sides. These gap seals protect the interior of the bearing from coarse contaminants; however, unlike contact seals, they do not cause any additional frictional torque. The rolling bearing is manufactured ex-works with standard radial clearance. The tight tolerance classes – P6 for dimensional accuracy and P5 for running accuracy – also ensure low-vibration and precise concentricity during operation.
