NFPA Style Hydraulic Rod Clamps RCH SERIES ROD LOCKS

The AMLOK® Rod Clamp has been developed to provide power-off clamping of rods and shafts. The type RCH Rod Clamps are actuated by a spring/ collet mechanism and unclamped by hydraulic pressure. These rod clamps are designed to clamp components after the motion has stopped and to hold the position securely as long as the forces do not exceed the table values. For braking applications, contact the factory. For air applications, call or visit www.ame.com for a pneumatic AMLOK® RLN catalog. When the potential for personal injury exists, or when life is in danger, SITEMA Safety Catchers are to be...

CLAMP/UNCLAMP RESPONSE TIME The AMLOK® clamps in 100msec and unclamps in 100msec, for a total cycle time of 200msec. These response times were calculated with a fast response solenoid valve located at the lock port and zero back pressure. MAXIMUM CYCLES PER SECOND Theoretically, an AMLOK® Rod Clamp can cycle five times per second. However, since an AMLOK® is designed to average one million cycles, frequent and repetitive cycling will reach 1,000,000 cycles in a shorter time. OTHER APPLICATIONS INCLUDE > Injection molding machines > Hydraulic presses > Amusement equipment > Theatrical equipment...

CLAMPED > Hydraulic pressure off > Zero back pressure UNCLAMPED > Hydraulic pressure at minimum > Release pressure not to exceed 3000 psi FOR HEAD RECTANGULAR FLANGE MOUNT (NFPA MF1 OR MF5) Ml 2x1 PORT FOR OPTIONAL PROXIMITY SWITCH (INDICATES UNCLAMPED CONDITION) Note: Contact Advanced Machine for other mounting styles. Example: RCH - 100 250 - 150 N 1.00” Rod - 2.50” Cylinder Bore 1500 PSI Release Pressure No Proximity Switch Movement in Load A direction is zero. Movement in Load B direction is .012” maximum when clamp is fully locked. RCH - XXX XXX Rod Size - X.XX (Inches) Cylinder Bore Size...

1 Maximum hydraulic release pressure: 3000 psi. 3 Rod tolerances that exceed these limits will affect the holding force. 2 Other sizes available upon request. 4 Holding forces are based on dry or mineral-oil lubricated shafts. Dimensions are subject to change without notice.

NOTE: When assembling the AMLOK® Rod Clamp, take precaution not to induce side loading. 1. Temporarily connect a flexible hose to a release pressure port of the AMLOK® Rod Clamp and apply specified hydraulic release pressure. 2. Line up the counter-bored end toward the mounting surface of the hydraulic cylinder or housing and slide the rod clamp over the rod to be clamped. 3. Align mounting holes, proximity switch, hydraulic pressure and breather plug to the proper location. 4. Release hydraulic pressure. 5. Bolt AMLOK® to cylinder or other mounting surface. 6. Pressurize the Rod Clamp to the specified...

SPECIFICATIONS FOR OPTIONAL PROXIMITY SWITCH (INDICATES ‘UNCLAMPED’ POSITION) AMLOK® PROXIMITY SWITCH SETTING 1. Set the AMLOK® to the undamped “pressure applied” position. 2. Screw the proximity switch (incl. Lock tooth washer) into the designated M12 x 1 proximity switch hole, until it contacts the piston flange. 3. Unscrew (back off) the proximity switch approximately 1 turn. While holding the proximity switch in the set position, tighten the locking nut using 15 ft. lbs. of torque. Final adjustment may be necessary to achieve desired results. 4. With the electrical power in the off position,...
