We are the leading importer, exporter, trader and supplier of Line Shaft, Safety Coupling, Disc Coupling and many more.. Power Locks are keyless shaft-hub locking devices designed to transmit torque through frictional contact, eliminating the need for keyways, splines, or other traditional fastening methods. They provide a secure, backlash-free connection between the shaft and mounted components such as gears, pulleys, or sprockets. Constructed from high-strength steel, Power Locks use tapered rings or wedge mechanisms that expand uniformly during tightening, creating a strong clamping force. This design ensures precise centering, high torque transmission, and resistance to axial and radial loads. Power Locks are ideal for applications requiring frequent disassembly, precise alignment, or enhanced torque capacity. They are commonly used in heavy machinery, automation systems, and power transmission assemblies.
