Qualified personnel Schaeffler VarioSense may only be mounted, commissioned, operated and maintained by qualified personnel. The scope of competence, area of responsibility and monitoring of personnel must be precisely regulated by the site operator. -
Page 10: Safety Regulations
Schaeffler VarioSense Safety regulations This section contains important safety regulations relating to working with Schaeffler VarioSense. Further guidelines can be found in the individual chapters of this user manual. General handling Schaeffler VarioSense is a sensitive measuring system. Shocks and compressive loads can damage the components, render the system unusable or result in erroneous output values. -

Finish laying the cable, observing the guidelines for laying cables, see page 20. Secure the outer ring against rotation. There are various methods available for securing against rotation, depending on the application, see page 18. Schaeffler Technologies BA 47... - Page 18 Schaeffler VarioSense Mechanical mounting The preferred mounting method for the sensor/bearing unit is by pressing on pressing on. The use of hydraulic presses is permissible. The procedure for mounting the bearing by pressing on is as follows: Apply a thin layer of Arcanol mounting paste to the bearing seating surface of the shaft.

Page 26: Operation
The values for the limiting speed can be found in the product tables and must not be exceeded, even under favourable operating con- ditions, without the consent of Schaeffler. The reference speed is used as an ancillary value for calculating the thermally safe operating speed and must be taken into consideration in the design of the bearing arrangement. -
