Jaw Coupling

Jaw Coupling - Clamping Screw Type



The JC Series is a structure in which 2 to 4 protrusions are made on a cylindrical aluminum material and high-elasticity polyurethane (SH98A) spacers are inserted between the protrusions. It is suitable for use in places with rapid rotational loads or frequent static and reversal. It is designed to be very easy to disassemble and assemble, and since the spacers are insulators, you can see the effect of blocking electrical noise.
