Swing Cylinder (Without Overload Protection)

Flange mounting, single acting / double acting


Description :

Swing cylinders are pull type cylinders. The piston rotates by 90 during the swing stroke, followed by straight clamping stroke due to the internal cam.

Application :

The clamping strap rotates by 90 while clamping and declamping. Due to the swing action, loading and unloading of the job is very easy. In the unclamped position, the workpiece area is free from the strap.

Versions :

Type of cylinder

  • SW - Single acting (spring return)
  • DSW - Double acting

Swing direction (While clamping & looking from rod side)

  • CW - Clockwise
  • CCW - Counter clockwise

Specifications :

  • Bore diameter - 30 mm.
  • Maximum oil pressure - 200 bar.
  • Minimum oil pressure - 20 bar.
  • Oil volume - clamp - 9.2 cc.
  • Oil volume - declamp - 19.8 cc.
  • Force at 150 bar - 5.0 kN.
  • Weight of the cylinder - 2.8 kg.

Notes :

  • To avoid damage to the swing mechanism
  • Hold the clamping strap in a vice or spanner, while tightening and loosening the cap screw (M 10).
  • Clamp the job in the straight clamping stroke only.
  • Double acting cylinders are suitable with the hydraulic power unit.
  • Single acting cylinders are suitable with the hydropneumatic intensifier.
  • Do not exceed the standard strap length.
  • Adjust the oil flow rate in such a way so that the total clamping time will be more than one second.
  • For height adjustment, either use a spacer at the mounting plate or adjust the clamping bolt on the strap. (fig. below )
  • For horizontal mounting of single acting cylinders, weight of the strap should assist the decamping swing stroke.
  • For single acting, spring return cylinder, a breather is provided. It should be protected from cutting liquids and coolants.
  • For ordering the seal kit, add the prefix "S" to the part number.
