- The jac Drum coupling is designed for installation in drum drive of crain and conveying system. The drum coupling can be used in the very difficult and rough operating conditions of iron and steel work and continuous heavy load operation in shore cranes.
- With compact design and capable of transmitting large radial load, enjoy longer life and minimim loss of power angular misalignment can be allowed up to 1.5 degree
- According to size of couplings, max 3~8mm of end float can be absorbed. Drum couplings are not suitable for transmitting axial forces.
- With design of decreasing slip movement of rollers by construction of min. backlash between crouned rollers and cylindrical bores, the relative movement between rollers and bores, which is cause of wear, is considerably reduced due to the natural movement of drum.
- In the trasnmission of power, a stampling hardness of the rollers profile is produced, with which higher wear resistence is achieved
