Product Identity

The Tritan 6308/C3 is a single-row radial ball bearing built to industry number 6308. It suits maintenance engineers and hobbyists who need a metric-dimensioned replacement for power-transmission equipment. The open closure leaves the rolling elements exposed for lubrication access in oily or greasy environments. Alloy-steel rings and AISI 52100 balls provide standard durability for moderate loads.

Installation Checks

Verify the shaft diameter is 40 mm and the housing bore is 90 mm before ordering. The bearing width is 23 mm, so confirm the available axial space in your assembly. Bore tolerance is +0/-0.012 mm; ensure your shaft fits this class. The open design requires an external seal or shield if contaminants are present. No retaining ring is included, so plan for separate axial location.

Operating Characteristics

ABEC 1 rating indicates standard running accuracy for general industrial speeds. Dynamic radial load capacity is rated at 9,100 lbf for basic life calculations. Steel cage and alloy-steel construction handle typical operating temperatures in lubricated systems. Open closure reduces churning loss but offers no barrier to ingress; expect noise levels consistent with unsealed metric bearings under normal lubrication.

Questions about this item

Does the 6308 bearing ship with a retaining ring or do I need to buy one separately?

The listing states no retaining ring is included, so you will need to source one separately if your application requires it.

Which ABEC rating and cage material suit a high-speed oily environment?

This unit carries an ABEC 1 rating and a steel cage, a combination intended for standard precision in oily or greasy conditions.

What does the 9,100 lbf dynamic radial load capacity mean once the bearing is mounted?

It indicates the maximum steady radial load the 40 mm bore bearing can carry at rated life under normal operating conditions.
