Speed (r.p.m.)
■ The max. gripping force is the total, acting on the 3 jaws, obtained by applying to the chuck the max. allowed driving torque. The data refers to a chuck newly maintained accordingly to their service manual, using SMW K05 grease. ■ The dynamic gripping forces have been measured using hardened standard stepped monoblock jaws placed in a position not exceeding the outer diameter of the chuck. Safety advice / danger of damage: When using taller / havier jaws and / or clamping on a more external position reduce driving torque / rotating speed accordingly.
Jaws radially adjustable
Jaws 180° reversed
