TO OBTAIN ALL THE BENEFITS FROM YOUR CYLINDERS
(1) When a cylinder is stored for future use, be sure it is amply lubricated, particularly inside the tube and on the piston rod, as packings will tend to adhere to dry metal surfaces over extended storage.
(2) A cylinder is NOT a structural unit nor a machine member. It is designed for one purpose only - to push and pull. It is not designed to be a guide or a machine way.
(3) Please be sure your alignment between the work and the piston rod at both ends of its stroke is faultless. Mis-alignment will cause mechanical interference and shorten the life of the cylinder.
(4) Wherever possible, please try to have a maximum of two points of alignment. It is difficult, particularly after servicing, to obtain an identical mounting to the original installation, due to tolerances and allowances on clearance holes, concentricity of threads, etc. When more than two points of alignment are encountered, your problems, multiply. If you use a rigid mounted cylinder (Foot, Flange) plan to allow some "float" to the piston rod end of attachment. On Pivot Mounted cylinders (Pivot or Clevis) plan to allow some "float" in the plane at right angles to the piston rod plane.
NOTE: Unless otherwise specified, cylinders will be furnished standard as follows:
(1) Port locations as shown
(2) Rod extension and threading as shown
(3) For temperatures service to 180° F
Cylinder components are stocked in stroke length increments of 1". Complete assemblies are not stocked but are made to order promptly from interchangeable parts.
Cylinders will be furnished in fractional stroke lengths, but with same overall length as the next longer unit inch at no additional charge. A spacer bushing in the rod end of the cylinder will restrict the stroke to your specifications. For example, a 1-1/8" stroke cylinder will have the same overall length as a 2" stroke cylinder, but the piston rod travel will be limited to 1-1/8" from its retracted position. If you require this space bushing on the blind end of the cylinder to limit the "IN" stroke please specify, as this is not standard, but is available at no extra charge. If you require that the cylinder overall length be reduced to match a fractional stroke, an extra charge is needed.
