6 www.jbj.co.uk/couplings.html #DriveLineHarmony Description ® JUBOFLEX Elastic Couplings » One elastic element made of pre-compressed, natural rubber, reinforced with steel to be fitted with fixing screws and a metallic band (to be removed after mounting). They are produced: » For mounting with SER-SIT® taper bushing from size 4 to 25. » Twometallic hubs made of forged steel (size 120 produced in cast iron). JUBOFLEX® couplings aremade of: » Solid hub from size 35 to 120., personnel and equipment is protected. » high safety factor and a very high resistance to alternating deformation, thanks to pre-compression; Features JUBOFLEX® coupling has exceptional elastic properties. » an excellent dampening effect of the load peaks; » possibility of bearing misalignment values rarely possible with other couplings. In this way it avoids the need of a precise alignment of the machines to be coupled. It is recommended to remove the metallic band of the elastic element after the coupling is mounted; pre-compression will be assured by the fixing screws. » GJ complete coupling solid hub. E.G.: GJ4 = complete coupling (2 hubs + 1 elastic element) with nominal torque of 40 Nm. To identify the desired size use the nominal torque of the coupling. Coding » AJ elastic element. » GJM hub. GJB4 - GJB25 GJ4 - GJ120
