How to Use the Clamping Force Tables 1) Start by choosing the arm length you need for your application. 2) Then move along the line and select the clamping force and operating pressure or operating pressure and clamping force needed. Example: Using a L1-4X25-00 with a 30 mm arm; the clamping force would be 1.4 kN at 5.0 MPa L1-4X25-00 Operating Pressure (MPa) Cylinder Force (kN) Clamping Force (kN) Arm Length “L” (mm)
= Non-Usable Range
• The tables and graphs show the relationship between arm length, operating pressure and clamping force. • The arm lengths shown in parentheses (page D-5) are the usable length from
the edge of the clamp body to the contact bolt. • Tables include maximum operating pressure associated with the arm length shown in the header rows of the table. • The column on the right of the table is the maximum arm length allowed at the associated operating pressure. • Operating the clamp in the
