www.jbj.co.uk/couplings.html #DriveLineHarmony ® JUBOFLEX 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) and two metallic hubs made of forged steel (size 120 produced in cast iron). ® They are also available for mounting with SER-SIT taper bushing from size 4 to 25; solid hub from size 35 to 120. Brass Couplings Hubs made in brass and spider in rubber. Suitable for low power. ® TRASCO Spider Couplings The flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class. It has a very compact design and allows safe power transmission by absorbing peak loads and torsional vibrations. The elastomeric design of the polyurethane gear ring compensates for angular, radial and axial misalignments. ® METALDRIVE Disc Couplings Made of steel and are used in all applications where high reliability, precision, and no maintenance are required. ® All the components of the METALDRIVE couplings are completely machined (spacer excluded) and balanced in class DIN ISO 1940-1 Q 6,3. ® TRASCO ES Spider Couplings » “Zero-backlash” motion transmission. » Dampening (up to 80%) of vibrations from motor shaft. » Low heat and electrical conductivity. » Easy and fast installation. » Perfect balance (A & AP type). » Low moment of inertia (due to compact design and types of materials used). ® SITEX Gear Couplings Two steel gear hubs, connected with one internally toothed sleeve of stabilized 6.6 super polyamide resin. ® ® SITEX NYLEX couplings are made of 100% Polyamide. Designed for light applications, low cost and available with finished bore keyway and thread for set screw. ® The SITEX FL couplings are designed to optimize the connections between diesel engines and driven equipment such as hydraulic pumps. 84 Summary Mechanical Power Transmission Couplings
