FAQ

What is the purpose of the ‘D’ and ‘/40’ in the H 310/40 D designation?

The ‘/40’ indicates a specific bore diameter of 40 mm for the shaft. The ‘D’ signifies that this is a “gedeeld” or “split” type sleeve, which simplifies installation and removal.

Which bearings are compatible with this H 310/40 D adapter sleeve?

This sleeve is designed for bearings with a tapered bore of 1:12, such as those in the 1310, 2310, 22210, and 23210 series. The bearing’s inner diameter must be 50 mm to match the H 310 series sleeve taper.

What are the correct tightening procedures for the included KM 10 lock nut?

The KM 10 lock nut should be tightened to remove the internal clearance of the bearing. This is typically done using the drive-up method, measuring the reduction in radial internal clearance, or by monitoring the required tightening torque/angle as specified by the bearing manufacturer. A hook spanner (e.g., HN 10) is required for proper tightening. Always use a corresponding lock washer (MB 10, not shown but required) to secure the nut.
