Deep Groove Ball Bearings SKF 6305 NR

The SKF 6305 NR deep groove ball bearing, measuring 25x62x17 mm and featuring an integrated retaining ring, provides a space-saving axial fixation within the housing.

The 6305 NR deep groove ball bearing is a single-row radial ball bearing to standard tolerance class P0/PN or ABEC 1. It features a ring groove with an inserted snap ring on the outer ring. This SKF design primarily accommodates radial forces as well as axial forces in both directions. As it is an open rolling bearing without sealing rings, the bearing operates with low friction and is suitable for lubricated systems within a temperature range of -20 to +150 degrees Celsius.

What is the 6305 NR deep groove ball bearing suitable for in operation?

Design engineers primarily use this design where axial installation space is limited. The snap ring provides axial retention directly within a suitable housing groove. This eliminates the need for separate retaining rings or housing covers with shoulder stops. Typical applications include compact designs with a closed lubrication circuit. The sheet steel cage guides the rolling elements, made from bearing steel, quietly even at higher speeds.

What advantage does the ring groove with snap ring offer during assembly?

The combination of the groove and snap ring facilitates the axial positioning of the assembly. During assembly, the snap ring engages in the groove of the bearing housing and prevents the outer ring from shifting. As this model has a standard radial bearing clearance, it is designed for standard operating temperatures and typical shaft fits. As there are no integrated seals, a clean operating environment or external sealing of the bearing housing is required.
