Continue to benefit from the characteristics of the S-Flex coupling but for 3 times longer! The new EPDM coupling sleeve element lasts at least 3 times as long as the previous design, saving you valuable downtime opportunity costs and maintenance costs.
» Easy to Install
» Maintenance Free
» No Lubrication
» Dampens Vibration and Controls Shock
» Torsionally Soft
» Double Engagement
The new material also provides at least 30% increased torque rating and allows for product downsize in 50% of applications creating an average cost saving of 23 - 33% for sleeve element replacement.
Extensive testing performed by the R&D department compared the new and improved EPDM S-Flex Endurance sleeve element material to the previous design and competitor’s similar style couplings. Ultimately the new EPDM S-Flex Endurance material met or exceeded performance in every testing category. Note the performance improvements are for the EPDM material only. The Neoprene and Hytrel® types remain unchanged.
The S–Flex (flexible sleeve) coupling design is comprised of three parts. Two flanges with internal teeth engage an elastomeric flexible sleeve with external teeth. Each flange is attached to the respective shaft of the driver and driven and torque is transmitted across the flanges through the sleeve. Misalignment and torsional shock loads are absorbed by shear deflection in the sleeve.
The shear characteristic of the S–Flex coupling is very well suited to absorb impact loads. The S–Flex coupling from jbj Techniques offers combinations of flanges and sleeves which can be assembled to suit your specific application.
