Connecting Shaft

SIJIE connecting shafts are typically used in jacks system and matches perfectly with jacks and couplings. The connecting shafts transfer the torque from the motor to the screw jack or from screw jack to screw jack. Our standard connecting shaft is made from #45 steel plating chrome and ends machines to standard keyways for couplings fitting.

#45 steel plating chrome, SS304, SS316 material are available
Standard Diameter：25mm, 30mm, 40mm, 45mm, 50mm,55mm, 60mm
Shaft torque from 10N.m to 160N.m standard
Connecting shaft area exceeds Max.distance between support, pillow blocks are required
selecting the suitable connecting shafts based on torque and rotational speed requirements
