Link clamp cylinders 70 bar BL7

Double-acting - linear clamp cylinder
Maximum force at 70 bar: 2.6 to 13.5 kN

Supply through counter-bores under the flange ring or through gas fittings

Link clamp cylinders 70 bar BL7 : Link clamp cylinders - Quiri

Characteristics

• fastening and supply flange at the top of the clamp
• supplied with supply O-rings
• rod and connecting rods supplied with pins and circlips but with no clamping arm
• versatility of cylinders, 3 lever direction are possible with only one cylinder reference

Design

• steel body with anti-corrosion treatment
• steel rod treated to prevent seizing and corrosion

Options

• clamping arm: see clamping arms for BL7
• metal scraper

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
