Rod Alignment Coupler

The Rod Alignment Coupler allows 1/16" of radial
float and 2° of spherical movement. This prevents
cylinder binding due to misalignment thus
extending bearing and seal life, and permits
greater tolerance between the centerline of the
cylinder and mating part for simplified installation.

Air-Oil Tank

Available in 5 practical bore sizes: 1

", 2", 3

5", and 8", the Air-Oil Tank includes a translucent
fiberglass tube which permits viewing of the tank
oil level from any position, internal baffles that
reduce foaming and aeration of the system oil
resulting in maximum cylinder control, and
standard angle mounting brackets (except 1

bore) easily removed for convenient fluid
port positioning.

How to Figure Length of Volume

The following equations are given to help you in selecting the right air/oil tank volume for your particular application.
Volume of Cylinder: • Cap End

Cylinder Bore Area x Stroke = Volume

• Head End

Cylinder Bore Area – (Piston Rod Area*) x Stroke = Volume *

Reference Page ACT-1-13 for Areas.

Length of Tank = Volume of Cylinder x 1.3** (See chart below.)

**30% minimum recommended reserve working volume.

Tank Bore Area

Final Length of Volume of Tank = Working length of tank + 2" minimum safety factor to prevent aeration of oil.

Note: Length must be at least 3".
