Deep Groove Ball Bearings SKF 6307 N

The SKF 6307 N deep groove ball bearing, with a 35 mm bore and a ring groove in the outer ring, offers a solution for space-saving axial fixings.

The 6307 N deep groove ball bearing is a single-row rolling bearing made from standard 100Cr6 bearing steel, with dimensions of 35 x 80 x 21 mm. Designed as an open bearing, it does not require integrated sealing washers and can be integrated directly into existing lubrication circuits. A sheet steel cage guides the rolling elements at operating temperatures ranging from -20 to +150 degrees. The rolling bearing complies with the standard tolerance class P0/PN (ABEC 1) and has standard radial clearance.

What is the 6307 N deep groove ball bearing suitable for?

This radial ball bearing is primarily designed to withstand high radial loads as well as moderate axial loads in both directions. This version is particularly suitable for designs where the bearing housing requires axial fixation via a retaining ring. Due to its open design, the bearing is particularly suitable for clean installation environments or sealed housings with oil or grease lubrication, where no external contamination can penetrate.

What is the function of the ring groove in the outer ring?

The suffix ‘N’ indicates a ring groove in the outer ring of the bearing. This groove is designed to accommodate a retaining ring, allowing the bearing to be secured axially in the housing without the need for additional housing shoulders or spacer rings. This saves installation space and simplifies housing machining. During design, care must be taken to ensure that the housing bore provides sufficient clearance for the retaining ring used.
