Calculation Example) CDG3FN20-100 (built-in magnet, flange type, ø20 mm, 100 stroke)

  • Basic weight: 0.09 kg (basic type, ø20 mm)
  • Additional bracket weight: 0.08 kg (flange type)
  • Additional stroke weight: 0.05 kg / 50 mm
  • Air cylinder stroke: 100 mm

Mounting procedure for clevis: (ø80 to 100 mm)

Mounting procedure for clevis: (ø80 to 100 mm)

Mounting procedure for rod end nut

Mounting procedure for rod end nut

  1. *1: Tighten the clevis bracket mounting bolts to the proper tightening torques detailed below.
      ø20 mm: 1.5 N·m, ø25 to 32 mm: 2.9 N·m, ø40 mm: 4.9 N·m
      ø50 mm: 11.8 N·m, ø63 to 80 mm: 24.5 N·m, ø100 mm: 42.2 N·m
  2. *2: Mount the flange type and foot type so that the distance 't' (clearance) of the rod end nut is at least 1 mm.
  3. *3: The direction of the rod end nut (for male thread) when mounting should be with the hexagonal part at the rod end. Apply the wrench to the hexagonal part.
