Allowable axial load

*1) The temperature 80°C includes temperature rise during rotation.
*2) The start-up torque does not change with the supply pressure or with non-use (remains within the maximum start-up rotation torque), but it does change with the rotation number.
*3) If using at a speed above 600 min-1 (r.p.m.), ensure rotation is in the direction in which the joint is fastened.
*4) Rubber / resin couplings are recommended due to their excellent absorption of off center, shocks, and vibrations.
*5) min-1: Number of rotations per 1 minute
