POSITAL provides a wide range of solid shaft solutions including synchro, clamp, and square flanges. Various metric and inch diameters as well as flats and keys are also available for solid shafts.
POSITAL FRABA encoders' mechanics are designed for high continuous shaft loads (up to 300 Newton continuous radial and axial force) which makes them very robust and offers an extended lifetime.

We offer a variety of couplings and brackets to mount the encoders in various applications.
Synchro Flanges were originally designed for use on motors and gearboxes. They are more compact than a clamp flange. Synchro flanges can be installed with clamping discs or directly onto the face with fastening threads. We offer various clamping disc options, mounting domes, and couplings.
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.

Square flanges are the most common flanges in the US and are extremely efficient to mount. These square flanges are offered in the common 2" and 2.5" sizes with several shaft options.
See our assortment of couplings.
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.

Through Hollow options are also available through POSITAL's portfolio. With this kind of design, the shaft completely passes through the body of the encoder.
