Product Description

Air cylinder that adopts a new air cushion mechanism.
[Features]
· Multiple-surface direct mounting with a square body and no brackets lets you freely choose the mounting surface.
· This enables space-saving designs for equipment.
· Slightly extended dimensions relative to the CU standard models.
· There is no protrusion of the cushion valve, and the width is the same.
· 3 types of mounting orientations can be accommodated according to the installation conditions.
· Approximately 2.4 times more allowable kinetic energy.
· Improved sound insulation (reduced impact of noise at the stroke end).
· Interchangeable mounting.

Precautions

Installation and Removal of Retaining Rings

  • *Use an appropriate pair of pliers (tool for installing a type C retaining ring) for installation and removal of retaining rings.
  • *Even when using an appropriate pair of pliers (tool for installing a type C retaining ring), proceed with caution as there is a danger of the retaining ring flying off the end of the pliers (tool) and causing bodily injury or damage to nearby equipment. After installation, make sure that the retaining ring is securely seated into the retaining ring groove before supplying air.

Selection

  • *Operate the cylinder to the stroke end. When the stroke is restricted by an external stopper or a clamped workpiece, sufficient cushioning and noise reduction may not be achieved.
  • *Strictly observe the limiting ranges for load weight and maximum speed (Graph 1). Also, the limiting ranges provided here are based on the condition that the cylinder is operated to the stroke end with proper cushion needle adjustment. If operated beyond the limiting ranges, excessive impact will occur and this may cause damage to equipment.
