Description |
General purpose, light to medium duty. An economical, maintenance
free coupling, used in a variety of
appli-
cations. Helical's most popular coupling
|
Stainless steel version of “A” series, with higher torque capacity
and torsional stiffness. Increased fatigue resistance. |
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.
|
A general purpose aluminum coupling,
used where more parallel misalign-
ment is required. Has a large range of
shaft sizes, with optional keyways.
|
Stainless steel version of “MCA(C)” series, with higher torque
capacity and torsional stiffness. Increased fatigue resistance. |
Metric dimensioned coupling, with metric fasteners. A light to
medium duty coupling for those preferring to work strictly in the metric
system. A general purpose coupling.
|
Stainless steel version of the “WA(C)“ series, with higher torque
capacity and torsional stiffness. Increased
fatigue resistance with all metric dimensions and fasteners.
|
|
Typical applications |
|
Used for encoder/ resolver applications, low torque pump, lead screw
and various other 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. |
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.
|
Good for encoder/resolver applications, moderate torque pump, lead
screw, and various other applications. |
Good for pump, conveyor systems, and industrial processing equipment,
where absolute reliability is required. Anywhere a rugged, tough, long-lasting
coupling is needed.
