FNC Series


The trusted TB Woods Form-Flex metal disc style shaft coupling has successfully been used in conjunction with composite shafting for many years. If an application has a large distance between the driver and driven ends, the traditional design would be to incorporate a steel drive shaft between the two flexible coupling units. However, using steel shafting in this way can have its disadvantages. Primarily, the weight of the connecting shaft could mean additional bearing mounts and inertia problems to the whole design especially when large span distances are required and again when using couplings suited to bore sizes of 25mm and above. (Max 400mm).  To overcome this the spacer shaft was supplied using a composite material shaft . The key advantages to using composite shafting lies its weight saving characteristics and the inherent nature to reliably transmit high torques with near zero torsional wind up.
