The Drum Gear Coupling is a specially designed advanced gear coupling. Its outer teeth are made into a sphere, with the center of the sphere on the axis of the gear. The teeth clearance is slightly larger than the general products and can transfer a greater torque and allow greater angular displacement, enjoying excellent performance and longer life.
ROD Curved-tooth Gear Coupling is one of the transmission products with core technology independently developed by Rokee and has established and reported corporate technical standards in the country. By combining with the standard coupling technology of advanced countries such as Japan and Germany, we optimized many detailed dimensions, and adopted the toothed design with a large pressure angle and short shaft design for the shaft hole, which reduces the length-diameter ratio, and has a more compact structure and excellent speed performance. The bolts of similar types are standardized and the parts are universal. Compared with the national standard couplings, our standard couplings can transfer more torque, with greatly reduced mass and small moment of inertia. It meets the European explosion-proof requirements and the comprehensive performance is greatly advanced. We highly recommend you to choose our products for better transmission performance.

The Cardan Coupling uses cross bearings to connect the flanges at both ends, which can transmit torque that is not on the same axis. The diagonal compensation can reach more than 25°, and the spline connection can compensate for the axial displacement in a large distance. With high carrying capacity and excellent transmission efficiency, Cardan Shaft is widely used in modern industrial fields.
SWC Universal Joint Coupling adopts integrated fork head layout, with the rotary diameter of 1600mm and torque transmission distance of more than 30m. Universal Shaft is widely used in steel rolling machinery, crane transport machinery and other heavy equipment fields.
SWP universal coupling adopts integrated fork head layout. Similar to the use of the SWC universal coupling, it is mainly used in the field of heavy-duty large equipment, with a rotary diameter of up to 1200mm.

Metal Diaphragm Coupling is a kind of high-performance metal flexible coupling, which compensates axial and angular displacements by the deformation of elastic diaphragm while transferring torque. It features with compact structure, large transmission torque, long service life, maintenance-free, high temperature resistance, acid and alkali resistance, and corrosion resistance, suitable for shafting transmission in high temperature, high speed and corrosive environment.
Rokee's RL Series Steel Laminae Couplings are independently developed on the basis of high-quality products from Europe and Japan. It has smaller volume, larger torque of the same type, more reasonable proportioning size, large compensation range, light weight and small moment of inertia. Special elastic gasket design is adopted in the hole connection part of bolt and diaphragm group, which greatly reduces the stress concentration in the hole edge part, eliminates the tear loss of diaphragm, and extends the service life. With modular design, the coupling assembly is simple and its maintenance and replacement are quick. The performance far exceeds the national standard JM series products, which are widely used in fan systems, steam turbine units and other important industrial fields.
