Flexible Shaft Couplings
THE ADVANTAGES OF FRONTLINE COUPLINGS
Frontline Couplings transmit torque through precision machined barrel shaped pins, which ride within self-lubricated fiber-reinforced polymer bushings. This patented "free floating" double engagement design gives the Frontline Coupling several advantages:
Easy to Install and Maintain
No special tools are required for the installation or removal. Pins and bushings can be easily replaced without having to move the coupling or the equipment.
High Misalignment Tolerance
The "free floating" double engagement design allows the Frontline Coupling to significantly reduce the adverse effect of lateral forces due to unavoidable misalignment. This feature greatly extends the bearing life of the driver and the driven equipment.
Angular Misalignment Axial Misalignment Parallel Misalignment
No need to lubricate, since the bushings are made out of low coefficient of friction, high strength, self-lubricated polymer compound.
Easy to Align
In the event that a laser or dial indicator is not readily available, a good alignment can still be achieved with the use of a straight edge placed across the outside of the precision machined hubs.
The hubs, the pins and the power ring are made out of 303 or 316 S.S. The bushings are fibre-reinforced polymer compound.
The polymer bushings provide shock and vibration dampening.
Low Inventory Cost
Only one-size bushings and pins are needed regardless of the size of the coupling. Also, the hubs and the power ring do not see any wear and therefore never need to be replaced.
Because of the polymer bushings, the two hubs are electrically isolated from each other and therefore prevent stray currents from traveling across and damaging the bearings.
Finished bore couplings are furnished balanced to AGMA Class 10.
