EGJ/EGP

Features

・Soft couplings reduces loss of rotational energy.
・High rigidity despite its softness, producing low rotation angle deviation.
・Two types of resin material, making it possible to separately select softness and torque properties.

・Also effective for mechanisms with low torque on the drive side which require accuracy and atable rotation.

・High reliability design, with roughly 10 times the rotation lifespans of  UJ and GJ couplings.

・electrical insulation:1000V

Cautions when using plastic couplings
・These couplings are made of plastic, and are therefore not as strong as metal couplings. Please keep this in mind when using these couplings.
・Do not exceed the set screw tightening torques specified in the table.
・Shafts can be inserted deeper than the dimensions of "B" indicated in the.
