The frictional losses in axial-radial cylindrical roller bearings, as with other rolling bearings, depend on different factors. For general information, refer to Friction.
The values for the frictional moment listed in the product table were measured in functional tests and are average values. They should be used as guideline values only. The tests were conducted under the following operating conditions:
- lubrication: grease, kinematic viscosity 150 mm2/s at 40 °C (105 °F)
- rotational speed: 5 r/min
- ambient temperature: 30 to 40 °C (85 to 105 °F)
- attachment bolts tightened to the recommended torque values (→ product table)
