Connecting Shafts

Connecting Shafts Introductions
Worm gear screw jacks are very good in multiple jack systems, synchronized as tandem drive via Connecting Shaft, because the torsional deflection of Connecting Shafts and couplings has little effect on positioning. Under heavy load, worm gear screw jacks are not designed for high use or heavy duty cycle applications. They also suffer from low travel rates or speed and low efficiency. However, the lack of efficiency inherent in worm gearing produces the self-locking benefit associated with worm gear screw jacks. Our Connecting Shaft matches perfectly with jacks and couplings to meet a wide range of system requirements.
 The Connecting Shafts transfer the torque from the motor to the jack or from jack to jack. Machined journals and keyways at each end, keys supplied for each end. Standard diameters of 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, other diameters available on request. Available in standard lengths up to 5000mm. Steel, Bearing Steel or Stainless Steel designs available. When connecting shafts length exceeds maximum distance between supports. Pillow blocks are required. Below charts with the information: permissible maximum distance between supports, shaft diameter, shaft torque, maximum permissiable speed (RPM).
