These torsionally stiff, light weight couplings are capable of transmitting high torques at high speeds while accepting significant levels of angular, radial, and axial misalignment. They are easy to install, suitable for hostile environments, require no lubrication and feature a high torque to weight ratio. Specific designs are available which meet the customer’s exact requirements. Standard units are compliant with API 671 (American Petroleum Institute) and ATEX 94/9/EC.

•	No maintenance
•	Standard and reduced moment designs available
•	Capable of being torsionally tuned to suit specific machinery requirements

Spring-applied, Hydraulically released brakes

•	On-site torque adjustment to precisely match application needs microprocessor control option for smooth stops independent of load on belt
•	“park-off” facility for fast pad changing without special tools
•	Controlled reversal of belt
•	Automatic release of belt tension
•	Stops in either direction
•	Robust, mine ready design

The G-Flex Series is an all-metal coupling that provides positive protection against the damaging effects of shock loads and vibration. Aluminum horizontal cover (T10), and all-steel vertical cover (T20) designs are available. G-Flex tapered grid couplings are an excellent choice where torsional flexibility/vibration damping are primary concerns.

•	Easy to assemble / replace
•	Part-for-part interchangeable with industry standard tapered grid coupling designs
•	Coupling sizes 1020 through 1140 in-stock in a range of standard bore sizes
•	Shot-peened tapered grid flex element for long life

Form-Flex metal disc couplings consist of two hubs, a spacer and two high strength carbon or stainless steel flexible discs. Modified and special designs are commonly supplied to meet specific application conditions. Available in carbon steel, stainless steel or with corrosion resistant coatings.

•	No maintenance
•	Zero backlash
•	Close couple, spacer and floating shaft designs available
•	Easy interchangeability

GC Series couplings feature unitized, straight-sided flexible discs for ease of installation. Up-to-date design targeted specifically for heavy industrial applications. These couplings provide increased torque capacity per size by taking advantage of the latest materials and design technologies.

•	Unitized Flex Packs
•	Easier, faster installation
•	Interchangeable with industry standard designs
•	Fewer sizes to cover a full range of applications
•	Reduced spare parts inventory
•	Lower total cost of ownership
•	Special designs avaiable for higher-torque applications

'Fail to safety' design for high cyclic and general stopping and holding duties. The LI/SSB is designed for end-shaft or through-shaft mounting.

•	Start/Stop parts have a low inertia which:
	-	Reduces acceleration times and allows more cycles per minute
	-	Reduces heat generated
•	Air applied clutch with full circle friction discs
•	Extremely fast response
•	Available in 1,2,3 or 4 plate designs to suit torque, heat, response and space requirements.
Air connections are non-rotating. For dry use only

Matrix 5H, 55H and 55H-PSP, pressure Applied Tooth Clutches offer positive drive connections for high torque wet and dry applications.

• The 5H range features a bearing supported drive flange for connection to a variety of drive components
• The 55H range features a double bearing supported pilot, provided to allow the attachment of pulleys, sprockets, or other drive components
• The 55H-PSP has the additional feature of single position engagement, the driven member is always accurately synchronized
