The bolt coupling is a rigid coupling. It is made of two halves, which are cast iron grade GG25 connected by means of bolts. It is maintenance and lubrication free. Additionally, its construction prevents fretting corrosion and allows for easy mounting and dismounting. Bolt Couplings The bolt coupling is designed to connect horizontal shafts with similar diameters. For different applications please contact our technical department. Universal Joints Between pins and bores there are: High precision universal joint, manufactured according to DIN 808/7551. Every model type is made of 2 hubs with forks and a central block. » P series: 4 bearings with solid pins. » E series: with sliding bushes. » H series: with needle roller bearings. 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 a + 80 °C. ® SITEX STCouplings ® SAFEMAX Torque Limiters Prevents damage to machinery happening through instant disengagement of the motor side from the driven side in case of torque overload, thus eliminating the risk of expensive downtime. In addition, these torque limiters, being torsionally rigid and backlash free, allow a rapid and accurate resumption of machine operations once the cause of the overload has been eliminated. ® SERVOPLUS Bellows Couplings An innovative modular type coupling perfect in all servo motor applications where high torsional rigidity, backlash free torque transmission, low inertia, and superior reliability are required. Wear and maintenance free. Working temperature up to 300°C. The aluminum hubs and the compact design provide low mass moment of inertia resulting in a reliable and maintenance free coupling for high speeds. The double disk pack execution has been designed for applications where radial misalignment exists. ® SERVOMATE Disc Couplings Specially designed for servomotor applications.
