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 each...

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 threaded...

Hydraulic Cylinders Swing Cylinders Large • Standard without an arm. • Single or double arms are available. • Can be mounted using four 3/8" cap screws, or the 1 7/8"-16 O.D. thread of the cylinder. • Optional components include a jam nut or a mounting bracket to replace old Jergens part number 60621. • Can be used as a non-rotating clamp. • Maximum recommended flow rate is 90 cubic inches (1475 cm3) per minute per clamp. (Approximately 1 second clamp time.) • Note: Arm length can affect clamping pressures. See chart , page 12, for more information. • Available in FixturePro™ Design Software...
