Deep Groove Ball Bearings SKF 6305 -2Z

The SKF 6305-2Z deep-groove ball bearing, measuring 25x62x17 mm, offers protection against coarse dirt on both sides for a wide range of industrial applications.

The single-row deep-groove ball bearing 6305 -2Z primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard 100Cr6 rolling-bearing steel in the SKF Explorer design, this bearing is characterised by its smooth running. This version has a cylindrical bore of 25 mm, an outer diameter of 62 mm and a width of 17 mm. The sheet steel cage ensures that the rolling elements remain stable even at higher speeds.

In which applications is the 6305-2Z deep-groove ball bearing used?

Typical applications are found in general mechanical engineering on rotating shafts and in drives operating at medium to high speeds. Thanks to the non-contacting cover plates, the bearing causes virtually no friction during operation. The unit operates reliably at operating temperatures ranging from -20 to +120 degrees. Users employ this component as a replacement part for bearing arrangements where there is moderate exposure to contamination and where lubricant loss is to be avoided.

What are the benefits of the 2Z cover plates and standard bearing clearance?

The suffix ‘2Z’ denotes gap seals made of sheet steel fitted on both sides. These discs protect the interior from the ingress of solid particles without causing sliding friction or heat build-up at the sealing lips. The integrated standard radial bearing clearance (class CN) is suitable for typical fit conditions and standard operating conditions without extreme thermal expansion of the shaft. Thanks to tolerance class P0 (ABEC 1) and the outer ring without a flange or groove, the component can be fitted precisely into standardised housing bores.
