Clamp flanges are the most versatile in assembly (i.e. clamping, use of front tapped holes, clamping discs). Clamp flanges can be installed in a variety of ways including flange adapters and mounting brackets. These typically have higher shaft loads available for applications.
POSITAL offers blind hollow shaft flanges (aka hub shafts) for a wide range of shaft diameters. With a blind hollow flange design, the shaft does not pass completely through the encoder but rather resides inside the housing therefore clamping rings
and set screws are used to mount the encoder on the shaft. Various anti-rotation tether options
allow easy assembly to any motor or machine frame.
No elastic coupling required
Reduces axial lengths over shafter versions
Versatility in mounting
Better environmental protection than thru-shaft units
