F ： Clamping force P ： Hydraulic pressure LH ： Clamp arm length CTR1 with clamp arm length (LH) = 50 mm at hydraulic pressure of 7 MPa, Hydraulic Clamping pressure P Clamping force F is calculated by force F (MPa) （7-0.840） /(0.706+0.00244×50)=7.4 kN (kN) Do not use the clamp in the nonusable range. It may cause damage to the cylinder and rod. CTR 0.4 CTR 0.6 Clamping force F = (P-1.34) / (1.47+0.00663×LH) Clamping force F = (P-1.30) / (1.04+0.00387×LH) Clamping force kN Clamping force kN Hydraulic Cylinder Max. arm length Hydraulic Cylinder Max. arm length ... - Page 5 swing time of the clamp arm is greater than the m : Mass (kg) shortest swing time in the graph shown below. （Use flow control valve with cracking pressure of 0.05 MPa or less.

Page 9: Caution In Use
A flat saddle type of gear puller should be piston rod to hold it and tighten locknut with a wrench. used when removing an arm not to convey any rotating force to the piston rod. Clamping position 0.5° ± 90° ±3° Unclamping position 5° Structurally, model CTR has a backrush of 5° at unclamping position. When swivel speed is fast or inertia of clamp arm is large, clamp arm may rotate as much as this backrush. Install clamp arm by setting clamping position always at first. - Page 10 Itami, Hyogo, Japan 664-8502 TEL. 072-777-3333 FAX. 072-777-3520 CERTIFICATE OF APPROVAL ISO9001 PA-576E-3 CLS-11E-6 2018. 09 2018. 09 Specifications are subject to change without prior notice.
