National Standard Couplings

Rokee can provide you with almost all of the national standard couplings. Our years of technological accumulation and progress ensure that we can better comply with the technical requirements of national standards, design and manufacture common standard products to meet customer expectations and specifications. Also, our abundant technology reserves ensure that your selection and procurement requirements of couplings, whether rigid, flexible, safe, large or small, are met immediately within most national standards.

• Drum Gear Couplings

  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...
