Description

The simple design of the S-Flex coupling ensures ease of assembly and reliable performance. No special tools are needed for installation or removal. S-Flex couplings can be used in a wide variety of applications.

Main features
  • Easy to install
  • Maitenance Free
  • No lubrication
  • Dampens vibration and Controls Shock
  • Torsionally Soft
  • Double Engagement

This flexible couplings 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. 

Lovejoy's S-Flex couplings offers combinations of flanges and sleeves which can be assembled to suit your specific application. 13 sizes are available with torque capabilities that range from 60 in-lbs (6.78 Nm) to 72,480 in-lbs (8189 Nm). The S-Flex flanges are offered in five models which are made from zinc die cast or cast iron. Sleeves are available in EPDM, Neoprene or Hytrel® to address a wide variety of application requirements.
