​Guardian Couplings


​Curved Jaw Series
More Info
Application
The Curved Jaw couplings can be utilized in many applications and serve as an all-purpose coupling. The basic design of the Curved Jaw allows for a higher torque capacity in a compact design.  The curved tooth has a greater contact area which gives it the high torque capacity, and reduces edge pressure.  It will accommodate axial, radial and angular shaft misalignments.  The hubs are produced from a variety of materials including; aluminum, gray iron, steel, sintered steel, and stainless steel. The spider elements are available in various durometer options in Urethane & Hytrel. The spiders can perform under normal duty cycle conditions to heavy duty cycles which include shock loading and can minimize torsional vibrations in the system. 
Advantages
Features & Advantages
  • Three Piece Design
  • No Lubrication Required
  • Variable Durometer
  • Urethane Elements
  • No Metal to Metal Contact
  • High Torque Capacities
  • Variable Hub Materials

LJW & SWJW Series
(Interchange)
More Info
Application
The LJW coupling is your basic industry standard jaw coupling, and is completely interchangeable to other popular manufactures. Guardian offers the LJW as a standard in steel and cast iron, but if required can also be produced from other materials. It features three material types on the spiders which include Buna-N, Urethane, and Hytrel. The LJW is a very economical solution, and will accommodate axial, radial and angular shaft misalignments. 
​
The Guardian SWJW coupling is identical to the LJW Straight Jaw, except that the spider element wraps around the jaw tooth circumference, and is held in place with a steel retaining band. This design eliminates the need to relocate the prime mover/driven unit, and saves a remarkable amount of maintenance time.

Advantages
LJW Features & Advantages
  • Three Piece Design
  • No Lubrication Required
  • Variable Durometer Elements
  • No Metal to Metal Contact
  • High Torque Capacities
  • Interchangeable to other domestic brands

​Gear Grip Series
More Info
application
A general use coupling that is best suited for applications with a large degree of misalignment up to 50 HP.  The Gear Grip Coupling is a three-piece highly flexible design which includes two hubs and a flexible sleeve.  Guardian offers three different sleeve materials including neoprene, urethane, and reinforced neoprene.  Depending on the series, the hubs are typically offered in zinc or sintered steel.
Advantages
Features & Advantages
  • ALIGNMENT - By-eye alignment eliminates precise measurement. This allows for a reduced assembly time and requires no special installation tools. Ideally, drive shafts should be aligned to minimize vibration and wear on the coupling and bearings. If excessive misalignment is unavoidable, the Gear Grip offers up to .090" parallel misalignment and 7.5 degrees of angular misalignment.
  • TORSIONAL DAMPENING - Neoprene and urethane rubber sleeve compounds provide excellent torsional vibration dampening. The load is distributed evenly over a wide splined contact area. This minimizes rubber deformation and wear while providing minimum backlash and wind-up. The Gear Grip coupling handles the shock, cycling loads, and vibration that produce extreme wear in other style of couplings.
  • IN-SHEAR DESIGN - The in-shear design allows the coupling to act as a mechanical fuse in the event of an overload condition. This feature can provide protection to the expensive drive system. If the coupling were to fail, only the coupling sleeve would need to be replaced.
  • ADJUSTABLE LENGTH - The coupling length can be adjusted to meet the application requirements. This is obtained by using a longer sleeve. Please note, the torque may be lower for longer sleeve lengths, and the end-user should contact Guardian for proper specification. A wooden dowel or insert may be used for longer lengths to prevent the collapse of the coupling sleeve under the loading. Increased length may decrease the torque capacity, but it will improve the misalignment allowance and dampening.
  • ENVIRONMENT - This lightweight and compact coupling is not affected by moisture, dirt, or abrasives. The non-corrosive metal ends and rubber provide a long service life that does not require lubrication or maintenance.
  • ELECTRICAL ISOLATION - No possibility of metal-to-metal contact under severe overload, wear, or coupling failure.​

​Guardex M & I Series
More Info
application
GUARDEX is a double cardanic curved-tooth gear coupling. This three-piece design is able to compensate for axial, radial, and angular shaft misalignment. The coupling consists of a nylon sleeve and two steel hubs.  As a result, creates a maintenance free product and doesn’t require any further lubrication.  It fits electric motor driven applications up to 300HP. They are perfectly interchangeable with other popular European designs.
Advantages
Features & Advantages
  • 1/2 HP - 294 HP
  • 1/4" to 3-3/4" Bores
  • Double Crowned Tooth Gear Coupling
  • Nylon Sleeves, Steel Hubs
  • Blind Assembly
  • Free Axial Travel
  • Splined Bores, Metric Bores

​Dynaline Series
More Info
application
Available in 4 sizes, the Dynaline is a single piece rubber-in-shear coupling. These couplings are used in sub-fractional thru 3HP applications, with torque ratings up to 54 IN-LBS. End fittings are made from zinc die castings, and are crimped to the rubber sleeve. Bore sizes up to 3/4" (19mm). The coupling length can be varied to suit many applications.
Advantages
Features & Advantages
  • One-piece construction - No assembly, no wearing surfaces, easier installation.
  • Corrosion-resistant end fittings are crimped to a neoprene sleeve to provide a maintenance free and longer life in difficult environments.
  • Added length provides maximum angular and parallel misalignment. No need to align driver to driven components.
  • Length to customer requirements.
  • Neoprene sleeve provides a vibration free coupling which absorbs the shock of start-stop applications and peak overloads.
  • Special designs or modifications engineered for the O.E.M. application​

Reuland Electric

RC Series Jaw Couplings
More Info
Application
Why should you specify Reuland Flexible Couplings? Reuland uses stronger materials.
Because flexible couplings are subjected to constant torque and stress, they eventually wear out. Obviously, the longer the coupling lasts, the more value you get for your money.
The key to flexible coupling longevity is the elastomeric element that is sandwiched between the coupling halves. Most flexible coupling manufacturers use compression-molded, rubber-like materials for their standard grommets. Reuland, however, uses a high-tech injection molded material called Lomod for our standard grommets. Torque tests and shock loads prove Lomod is stronger and more durable than most of our competitors' standard elastomeric elements.
Advantages
  • ​Reuland flexible couplings cost less.
  • Reuland flexible couplings are made from lightweight aluminum.
  • Reuland flexible couplings are precision machined. 
  • Rigorous Quality Control.
  • Specials, Metrics and Splines.
  • The One Source for all Your Flexible Couplings and Pump/Motor Adapter Needs. 
  • Fast Delivery.
  • The Reuland Guarantee.
