2.4.1 Shaft ends and bearing configuration
To reduce the amount of design work required, we provide standardised end machining
processes and bearing units. We recommend the “B”, “E” and “F” bearing series for
simple transportation applications and low axial forces. The SFA and SLA bearing units
are suited to more challenging precision applications. The WBK series is available for
heavy-duty applications.
When selecting the suitable bearing type, the permissible axial force of the fixed
bearing must also be taken into account.
