SITEX® ST gear couplings available from jbj Techniques Limited #DriveLineHarmony Introduction ® SITEX ST Gear Couplings 1 Description ® SITEX ST couplings are fully manufactured in high quality steel. They are made of 1 or 2 geared hubs which are coupled with one sleeve through which the torque is transmitted. The special OPTIGEAR profile allows very high torque transmission and the compensation of axial, angular and radial misalignment (only in the version with 2 hubs). The maximum recommended working temperature is -10°C to + 80°C. For special applications special materials should be used. Please contact jbj Techniques Limited technical office, telephone: +44 (0)1737 767493 or email for information. Features With the special design of the OPTIGEAR crown, the contact surface area under misalignment is larger than conventional crown. This results in the surface stresses being reduced resulting in a longer coupling life. Therefore, backlash is reduced to a minimum, reducing impact load in reverse application, and allowing optimum torque transmission and low vibration. All this results in an improved machine design. OPTIGEAR Profile ® SITEX ST couplings are machined with the unique OPTIGEAR profile, ensuring backlash is reduced to a minimum reducing impact load in reverse applications and allowing optimum torque transmission and low vibration. The result is a compact coupling keeping the application machine design optimized in size and work capacity. Interchangeability The range GST CF “A-B-C” conforms to AGMA specification in flange dimensions, type and positions of the screws. They are therefore interchangeable with ® any other AGMA coupling half. The most compact solution due to the exceptional torque transmission capability, SITEX ST couplings are the most compact solution in weight and dimensions for a safe torque transmission.
