Table 7.3: Permissible bore diameter
Figure 7.3: Specifications for the form and positional tolerance of the bore
The design and inspection of the keyway connection falls to the operator and is his responsi-
bility.
The gear couplings in the catalogue are designed with bore tolerance and keyway tolerance
per AGMA 9002-C14
.
Deviating fits are possible and should be communicated to RING-
SPANN as part of any query.
