Table 6.2: Fit pairs
The tolerance field must be observed in order to restrict the hub tension resulting from
the oversize to the permissible load. Failure to adhere to the assigned tolerance zones
may impair the shafthub connection.
Failure to observe these instructions may result in breakage of the coupling.
Danger from flying fragments!
6.1.1.1 Parallel keyway
With the parallel key connection to DIN 6885/1 and
a single keyway
the tolerance zone of the hub keyway
width
ISO P9
is recommended.
With the parallel key connection to DIN 6885/1 and
two keyways
the tolerance zone of the hub keyway
width
ISO JS9
is recommended.
6.1.2
Axial securing in case of parallel-key connection
A set screw or end plate must be provided to secure the coupling parts axially. If end plates are used,
Flender must be consulted with regard to machining the recesses in the coupling parts.
