Clamping arm for BL7 LS7 / LL7

For link clamp cylinders BL7

Characteristics

• made in steel with anti-corrosion treatment
• maximum service pressure 70 bar

• the clamping force decreases in proportion with the arm length (see calculation formula opposite).
• the dimensions of the interface of the flange with the clamp are stated if the flange is made by the customer.

Force calculation

Clamping force (Fb) depending on the arm length (h) and pressure (P)
Fb = ( S x P x l x 0.9 )/h
S = piston surface in cm²
l = clamp/connecting rod centre distance in mm
P = service pressure in Bar
h = centre distance between connecting rod and clamping point in mm
