Advantages of Frontline Couplings
While the frequency of parts replacement depends on application and field conditions, most standard applications do not require any maintenance until after three years.
No Lubrication Required
01 The only maintenance on Frontline Couplings is the sporadic replacement of Pins & Bushings.

advantages
Advantages of Frontline Couplings
Frontline Couplings can accommodate a high degree of angular, axial and parallel misalignment while maintaining high torque and greatly reducing the damage caused by lateral reactionary forces.
High Misalignment Tolerance
02 Frontline Couplings can accommodate 5⁰ of angular misalignment per engagement.

advantages
Advantages of Frontline Couplings
Even if a Frontline Coupling is allowed to run until all the bushings are worn and there is metal-to-metal contact, the Coupling will always maintain a positive engagement, allowing the equipment to operate until the next scheduled shutdown.
Fail-Safe Design
03 Frontline Couplings will never cause a forced outage.

advantages
Advantages of Frontline Couplings
Unlike most Grid, Gear and Disc Couplings, Frontline’s Pin & Bush design allows for rapid parts replacement in the field without disturbing shaft alignment.
Easy to Maintain
04 Spare parts can be quickly replaced without having to move the driver or driven equipment.

advantages
Advantages of Frontline Couplings
Low Inventory Cost
All sizes are organized by 8 “Series”, allowing customers to use the same size Pins & Bushings for multiple size couplings within that Series, decreasing inventory cost and simplifying storeroom management.
Easy to Inspect / Visual indication of relative wear
Users can quickly assess spare parts wear without having to move equipment or disturb alignment. Relative wear can be monitored during equipment operation with the use of a strobe light by marking a line axially across the hubs O.D. at time of installation.
Limited End Float Applications
Limited End Float Pins can be used to keep the rotor within the allowable float, preventing it from hitting the motor bearings’ thrust faces.
Made in USA
All design and manufacturing is done in the U.S.A.

advantages
Advantage of Frontline Couplings
Frontline Couplings incorporate a patented bushing design that provides several additional advantages.
Vibration Dampening
01
The rubber coated bushings provide shock & vibration dampening, leading to longer equipment life.
Electrically Isolated
02
The rubber coated bushings also prevent stray current from traveling across hubs and damaging bearings on the driven equipment.
Chemically Resistant
03
Chemically resistant to various PH levels.

Rapid Delivery & Customization
Our large inventory of standard sizes and raw material allows us to make very fast deliveries in emergency situations. Because of our complete control of the design and manufacturing process, we can quickly accommodate custom installations.
NON-STANDARD LENGTH HUBS
To meet specific design requirements, non-standard length hubs can be provided.
NON-STANDARD DIAMETER HUBS
Custom diameter hubs can be designed and manufactured to fit the required coupling envelope.
PARTIALLY SPLIT HUBS
This option combines the ease of a clearance fit installation with the reliability of an interference fit – goes on like a clearance fit, stays on like a clearance fit.
SPLIT DROP-OUT SPACER
To accommodate applications where a solid spacer could not be taken out to service the coupling.

Model SP-A – Spacer Type A
The Spacer Model “A” consists of two Hubs with Bushings and a Spacer Cylinder with Pins on each side. This arrangement can accommodate Parallel, Axial and Angular Misalignment.
Learn more
Model SP-B – Spacer Type B
The Spacer Model “B” consists of two Hubs with Pins that engage with a Cylindrical Spacer with Bushings on each side. This configuration allows for smaller diameter hubs reducing the weight of the coupling assembly and can accommodate Parallel, Axial and Angular Misalignment.
Learn more
Model SP-C – Spacer Type C
The Spacer Model “C” consists of a Cylindrical Spacer with Bushings on each side engaging with Pin Adapters that bolt on to Rigid Hubs. This allows for quick retrofitting of a Gear, Grid or Disc Coupling to the Frontline Pin & Bush design using the existing Rigid Hubs. This arrangement can accommodate Parallel, Axial and Angular Misalignment.

Model SD-SP-INV-A – Split Drop-Out Spacer A with Inverted Hubs
This configuration of hubs carrying bushings and a split spacer with pins allows for pin removal/installation through the inverted hubs. This arrangement can accommodate Parallel, Axial and Angular Misalignment.
Learn more
SD-SP-INV-B – Split Drop-Out Spacer B with Inverted Hubs
This configuration of hubs carrying pins and a split spacer with bushings, used when there is minimal clearance between the coupling and the driver/driven equipment, allows for pin removal/installation through the split spacer. This arrangement can accommodate Parallel, Axial and Angular Misalignment.
