Oldham couplings / body: steel, cast iron / RD / KAYSEVEN

Compact, simple structure, with easy to absorb eccentricity and centering. Widely used in robots, resin molding materials, conveying equipment, printing machines, machine tools, and pumps etc.

[Features]
· Compact and simple structure.
· Like the MD series, it consists of three parts, the hub parts and an intermediate torque transmission part.
· Oldham type coupling absorbs eccentric misalignment.
· Dial gauge is not necessary for centering work at installation.
· Visual observation is sufficient.
· The intermediate torque transmission part is made of resin, and so does not require lubricant.
· No reactive force due to misalignment, contributing to energy conservation, with assembly and installation easy.
· Simple structure, and even in the event of damage to the intermediate transmission part, power transmission is possible.
· Thermally and electrically insulated by the intermediate transmission part.
· Friction joint employed for fastening to shaft.
