GS Backlash Free Couplings
REACH GS coupling is ideal for use in applications that require precise positioning of drives. Despite its vibration-damping properties, this GS coupling is torsionally stiff, ensuring that precision isn't sacrificed even when using highly dynamic servo drives. Furthermore, it compensates for simultaneous axial, radial, angular installation deviations and compound mounting misalignments.
Our GS coupling has 4 different rigidities of elastomer differentiated by the colors, the materials range from soft to hard, based on different occasions. It is easy to choose the materials to meet the requirements torsional rigidity, vibration control etc. The prestress is determined by the type of the coupling and elastomer; The materials and inserting force during assembling are determined by the hardness of the elastomer and the prestress.
Features
Widely used in various mechanical and hydraulic fields;
No backlash, rigid in twisting direction, so the transmission is assured;
High precision in transmission and high rotating speed;
Application in a wide range of environments, the highest applicable temperature is 280 degrees;
Good elasticity, high strength, wearable;
No need to lubricate, quiet operation, no wear or slipping, reducing energy loss;
Quick and easy mounting and disassembly;
Small dimension, low weight, high transmitted torque;
Elastomers made of polyurethane with shore hardness between 64-98;
Compensating the axial relative drift, buffer, and vibration reduction.
Advantages
Mass production of metal parts, self-produced elastomers, using high-quality German TPU materials
Explosion-proof certification
Instantly exceeding 50% of the maximum torque value can still meet the transmission requirements
Passed the high and low-temperature life test, can still be used under the maximum load
Perfect coupling test platform
