Model SP-A
Spacer Coupling
The Spacer Design consists of Two Hubs with Bushings and a Spacer Cylinder with Pins on each side. This arrangement can accommodate Parallel, Axial and Angular Misalignment.
THE ADVANTAGES OF FRONTLINE COUPLINGS
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.
Electrically Isolated
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 on the driven equipment.
Dynamically Balanced
Finished bore couplings are furnished balanced to AGMA Class 10.
Easy to Install & Align
No special tools are required for installation or removal. 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.
Environmentally Tough
The hubs, pins and power ring are made out of 303 and 316 S.S. The bushings are a fiber-reinforced polymer compound.
Vibration Dampening
The polymer bushings provide shock and vibration dampening leading to longer equipment life.
Maintenance Free
No Lubrication required since the bushings are made out of a low coefficient of friction, high strength, self-lubricated polymer compound. In the event that the pins and bushings need to be replaced, this can be easily done in the field without disturbing the equipment.
Low Inventory Cost
Only one-size bushing and pin are needed for each Coupling Series regardless of the coupling size. Also, the coupling hubs and power ring never see any wear and therefore never need to be replaced.
Easy to Inspect
Coupling condition can be inspected while it is running through the use of a strobe light.
COUPLING APPLICATIONS
The Spacer Design is normally used
with End Suction Pumps to facilitate the
removal of the “pull out” section without
having to move the motor.
