Description
Maintenance-free operation.
Noise and frequency absorption.
Multi-lubricationable.
hydrodynamic operation possible
High permitted load.
Good friction characteristics.
High slide speed.
No water absorption.
To be used when oil film formation difficult.
low play during operation.
Extremely space-saving.
Note
An initial lubrication with grease is recommended and continual lubrication significantly increases the service life of the friction bearing.
Peak to valley height of shaft to be observed Ra < 0.8 μm.
Hardness of shaft to be observed 200 < HB < 600.
