Link clamp cylinders 250 bar BL25

Double-acting - linear clamp cylinder
Maximum force at 250 bar: 4.1 to 15 kN

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

Link clamp cylinders 250 bar BL25 : 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

Design

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

Options

• clamping arm: see page 99
• metal scraper

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
