W Series

W Series Flexure, Flexible Couplings


General purpose, light to medium duty. An economical, maintenance free coupling, maintenance free coupling with dimensions, used in a variety of applications.

Typical Applications
Used for encoder/resolver applications, low torque pump, lead screw and various other applications.

Misalignment Compensation
5° angular, .25mm parallel offset, 25mm axial motion
DS Series

DS Series Flexure, Flexible Couplings


Low inertia, high performance, aluminum coupling, using Helical double start technology. Torsionally stiffer and higher torque capacity than the “A“ series. Lighter with lower inertia than the “H” series.

Typical Applications
For high speed motion control systems, where fast response time is important. E.g., lead and ball screws, encoders/ resolvers, and anywhere high torsional stiffness is required.

Misalignment Compensation
3° angular, .010 inch parallel offset, .008 inch axial motion
MC-Series-MCblank

MC Series Flexure, Flexible Couplings


A general purpose aluminum coupling, used where more parallel misalign- ment is required. Has a large range of shaft sizes, with optional keyways.

Typical Applications
Good for encoder/resolver applications, moderate torque pump, lead screw, and various other applications.

Misalignment Compensation
5° angular, .030 inch parallel offset, .010 inch axial motion
A Series

A Series Flexure, Flexible Couplings


General purpose, light to medium duty. An economical, maintenance free coupling, used in a variety of applications.

Typical Applications
Used for encoder/ resolver applications, low torque pump, lead screw and various other applications.

Misalignment Compensation
5° angular, .010 inch parallel offset, .010 inch axial motion
H Series

H Series Flexure, Flexible Couplings


Stainless steel version of “A” series, with higher torque capacity and torsional stiffness. Increased fatigue resistance.

Typical Applications
For situations requiring a heavy duty coupling such as pumps, lead screws, and positioning systems; also for process equipment in industrial situations. Anywhere a rugged, tough, long-lasting coupling is needed.

Misalignment Compensation
5° angular, . 010 inch parallel offset, .010 inch axial motion
X-Series-2pcswtbkgd

X Series Flexure, Flexible Couplings


The X-Series couplings offer a cost effective balance between couplings that are too stiff radially and those not stiff enough torsionally for servo-type applications. It features high torsional stiffness, low radial loads, one piece integrity, good flexibility, and zero backlash. Created for high performance motion control systems, the X-Series incorporates two flexible element sets - combining greater end-to-end rotational accuracy with radial flexibility - in one design.
PowerFlex PF Series

PowerFlex PF Series, Flexible Couplings


The PF Series incorporates the convenience of interchangeable bushings, providing for quick and easy changes in bore sizes, while using the same HELI-CAL flexible coupling center section. By designing the tapered bushings to hold more torque than the maximum torque capacity of the coupling, the need for keyways has been eliminated.
