Characteristics and Effectiveness Information
The S-Flex coupling style and design is comprised of three elements: two flanges with inner teeth engage an elastomeric flexible sleeve with external teeth
Torque is transmited through the flanges mounted on both the driver and driven shafts by means of the sleeve
Misalignment and torsional shock loads are absorbed by shear deflection inside the sleeve
The shear characteristic with the S-Flex coupling is quite nicely suited to soak up impact loads
The S-Flex coupling gives combinations of flanges and sleeves which 
could be assembled to suit your particular application
Thirteen sizes can be found with torque abilities that range from 60 in-lbs to 72,480 in-lbs
The S-Flex flanges are made available in 5 models that are produced from zinc or cast iron
Sleeves are available in EPDM rubber, Neoprene to handle a wide variety of application prerequisites
Safety from misalignment, shock, and vibration:
PARALLEL:
The S-Flex coupling accepts up to .062 in of parallel misalignment without the need of wear. The flexible coupling sleeve minimizes the radial loads imposed on gear bearings, a problem normally associated with parallel misalignment.
AXIAL:
The S-Flex couplings might be used in applications which need a restricted volume of shaft end-float with out transferring thrust loads to tools bearings. Axial movement of about 1/8 inch accepted.
ANGULAR:
The flexing action of the elastomeric sleeve as well as locking characteristic on the mating teeth enables the S-Flex coupling to properly manage angular misalignment as much as 1??.
TORSIONAL:
S-Flex couplings properly dampen torsional shock and vibration to protect connected gear. The EPDM and Neoprene sleeves have torsional wind-up flexibility of 15?? at their rated torque. Hytrel gives 7??wind-up.
