Advantages

HIGH MISALIGNMENT TOLERANCE

Angular, Axial and Parallel misalignment can be accommodated without transmitting lateral reactionary forces to the equipment.

FAIL-SAFE DESIGN

The Frontline Coupling will never cause a forced outage.

NO LUBRICATION REQUIRED

The only maintenance is sporadic replacement of Pins & Bushings.

EASY TO MAINTAIN

Pins & Bushings can be replaced in a fraction of the time required to maintain a Grid, Gear or Disc Coupling.
