Schaeffler Mounting Manager

Schaeffler Mounting Manager

The Schaeffler computer program Mounting Manager is a user-friendly aid for ensuring the correct mounting of bearings with tapered bore and offers the following options:

  • it shows various mechanical and hydraulic mounting methods
  • it calculates the data required for mounting in relation to reduction in radial internal clearance, displacement and start pressure
  • it gives useful mounting advice
  • and it generates a list of the accessories and tools required

Calculation possibilities for mounting methods

Bearings with a tapered bore are mounted either directly on the tapered shaft or journal, or by means of an adapter sleeve or withdrawal sleeve on the cylindrical shaft. The internal clearance is set either by conventional means using feeler gauges or by means of the axial displacement.

a) Mounting of bearings with tapered bore by measurement of the axial displacement

The bearing is placed in its starting position on the tapered bearing seat with a hydraulic nut. The required starting pressure defined for each individual bearing is set in the hydraulic nut by means of the digital manometer. The displacement as indicated in the table can be measured either by means of a depth gauge, slide gauge or a dial gauge. However, the final measurement of the radial internal clearance is always done by using a feeler gauge.

This mounting method:

  • gives considerably shorter and simpler mounting
  • offers very high security and accuracy
  • allows the correct mounting of sealed bearings

b) Mounting of bearings with tapered bore by measurement of the reduction in radial internal clearance

When the bearing is pushed onto the tapered seat, the inner ring is expanded and the radial internal clearance is thereby reduced. This reduction in radial internal clearance is valid as a measure of the firm seating of the bearing. It is measured by means of a feeler gauge.
