The AMLOK(R) Hydraulic Series RCH Rod Clamp from Advanced Machine & Engineering (Rockford, IL) is designed to clamp components after the motion has stopped and to hold the position securely as long as the forces do not exceed table values. The clamp’s mounting is designed to apply to heavy-duty NFPAstyle MF1 cylinders.
The clamp comprises an alloy steel housing containing a special locking mechanism actuated by a set of disc springs. Holding force depends upon the rod diameter and the amount of hydraulic pressure available for unclamping. The clamp is designed for locking reciprocating motions only; special units are available for both rotating and reciprocating motions.
