AACQ series Large Bore Compact Cylinder
Description
・Compliant with JIS standards.
・The cylinder body is secured to the front and rear covers with C-rings for compactness and reliability.
・The inner diameter of the cylinder is precision machined and then hard-anodized for wear resistance and durability.
・The piston seal utilizes a special-shaped, bidirectional seal structure, offering compact dimensions and oil storage.
・The compact design effectively saves installation space.
・Sensor grooves are located around the perimeter of the cylinder body for easy sensor installation.

| [Note] 1. Non-standard strokes within the maximum stroke range are modified from the next higher standard stroke. Their external dimensions are those of the next higher standard stroke cylinder. For example, an ACQ160 non-standard stroke cylinder with a 35mm stroke is modified from a standard 40mm stroke cylinder. Its external dimensions are 131mm. 2. Special strokes are modified for special requirements. For example, an ACQ160 special stroke cylinder with a 35mm stroke uses a special 35mm stroke cylinder. Its external dimensions are 126mm. |
