Deep Groove Ball Bearings SKF 6306 -RS1

The SKF 6306-RS1 deep groove ball bearing combines a single-lip seal with a high load-carrying capacity for shafts with a diameter of 30 mm (30x72x19 mm).

The single-row deep groove ball bearing 6306 -RS1 is a versatile rolling bearing made from standard 100Cr6 bearing steel. It accommodates radial loads as well as moderate axial loads in both directions. This design features a single-sided sliding seal (RS1), whilst the opposite side remains open. The inner and outer rings are matched to one another and comply with the standard tolerance class P0/PN (ABEC 1) with normal radial clearance. A robust sheet steel cage guides the rolling elements precisely within the raceway system.

Where is the 6306-RS1 deep groove ball bearing best suited for use?

This radial ball bearing is ideal for applications where one side of the bearing housing must be protected against the ingress of dirt, whilst the open side requires access to an internal lubrication circuit. Typical applications are found in general mechanical and plant engineering for shaft mountings with single-sided lubricant supply. Thanks to its permissible temperature range of –20 to +120 degrees, the bearing operates reliably under standard industrial operating conditions. The 30 mm cylindrical bore facilitates precise installation on standard shafts.

What is the function of the single-sided RS1 seal?

The factory-fitted RS1 seal rests in contact with the inner ring shoulder. This effectively shields the interior of the bearing on this side against dust and dirt particles. At the same time, the open opposite side allows for targeted relubrication via the interior of the housing, for example in oil bath or recirculating lubrication systems. Thanks to the standard radial bearing clearance, the bearing is designed for typical operating temperatures and tight fits without generating excessive stresses during operation.
