Power Clamping Devices www.jergensinc.com Designing Your Own Hydraulic System 1. Calculate the force used to hold the workpiece during machining. To convert the torque applied to a fastener into holding force use the following formula: P= T KD P = Holding Force (kN) T = Torque (N.m) D = Nominal Thread Diameter (mm) K = Friction Factor (K Varies with material, finish, and lubrication, .19 to .25) Where: Example: M12 bolt tightened to 50 N.m P= 2. Calculate the force required at each work unit. Total Force = Force per unit Number of work units 3. Select the style of work unit to be used at...

Hydraulic Cylinders Jergens www.jergensinc.com Swing Cylinders These versatile swing cylinders/clamps can be used as single or double acting rotating clamps, or push/pull cylinders. The piston in the Swing Cylinders rotate 90° to the right, but may easily be changed to 90° left rotation, or to no rotation at all. WARNING: All swing cylinders must be used with flow limit valves (page 14, 74) to dampen the rotating action. Please see maximum flow rate shown below. • Can be mounted using four #10 cap screws or the 1 "-12 thread on the O.D. of the cylinder • Optional components include the...

Hydraulic Cylinders Jergens.www.jergensinc.com Converting Manual Power to Hydraulic Pressure If you are currently using bolts, nuts, straps, etc. to hold a part on a fixture, use this chart to help decide how much hydraulic holding force would be needed to convert the set-up to hydraulic clamping. * Bold type represents the average torque generated by the operator with a 300mm wrench. P = Induced Tension (kN) T = Torque (N.m) D = Nominal Screw Diameter (mm) K*= Friction, varies with material, finish, & lubricity (.19 to .25) *Above values based on K equaling .22 Phone 800-537-4367 or...
