Disc Coupling

Flexi-disc Coupling is torsion ally rigid with zero backlash ideal for use as non-lubricated couplings for Pumps, compressors, fans, Turbines, Blowers and other rotating equipments. It transmits mechanical power to driven machines through shaft mounted hubs connected by the coupling and flexible disk packs. Both angular and axial misalignments are accommodated by the flexible disc packs.

Flexible Disc Couplings

  • The flexible disk coupling is very similar to the diaphragm coupling.
  • Multiple, thinner discs are used as the flexing element instead of circular, contoured Diaphragm elements.
  • Two disc packs (or diaphragms) are needed to accommodate parallel misalignment.


  • Low Maintenance
  • Minimal End Thrust and Bending Moments
  • Significant levels of Angular, Radial & Axial Misalignments Accepted
  • Excellent Power to Weight Ratio
  • Zero Backlash
  • Can Be Adapted to Operate in Explosive Environments to Cater to "Spark Free"


  • Minimum Residual Imbalance

Base Frame

We design, manufacture, supply & commission for frame to meet the design requirement.

All design loads motor generator max reaction force, dead load, transportation and handling load etc are considered for design.

We have proven skill and facility to manufacture small to large size base frame meeting the design requirement.

Our Expertise

Laser Alignment:

We have facility to do onsite alignment of equipment to be coupled , laser alignment tool as well as manual dial gauge alignment tool are available. We reconfirm the correctness of alignment by vibration analysis method.

Locking Device

      This friction type locking device allows easy, strong, and secure connections between shafts and hubs without backlash.

      Locking devices are unique keyless, frictional shaft-hub locking devices which provide an easily-adjustable and releasable shrink fit. Advantages: Elimination of keys and keyways on both shafts and hubs No backlash - completely tight fit around the shaft Unaffected by reversing, dynamic or shock loads. Easy assembly and disassembly. Ease of axial and angular adjustment or timing.


      With this design the Safeset pressure ring plays no active role in the torque transmission. The ring merely exerts a static radial force onto a torque transmitting connection sleeve, pressing this against the shaft or shaft sleeve. Thereby higher dynamic bending moments and radial forces can be transmitted by the Safeset.

Shear Pin

     This is a age-old cost effective method of limit the maximum of transfer & protecting the gear train.

     The material of transmission and geometry of pin is designed that the failure is only for over load torque and not due to fatigue.
