A word about Rod Gland seepage
When the rod end of a cylinder is open to exhaust or tank, there is usually little or no back pressure to keep the rod gland packer lip tight against the piston rod. A microscopic film of oil can therefore go out on the advancing piston rod. However, on the retract stroke, the rod end is pressurized, and the packing lip is forced against the piston rod to seal it.

Most of the seepage problems come from the sealed rod gland packer scraping the rod clean. The microscopic oil film from the previous advance stroke collects to for a drop of oil.

GUARANTEE
Our products are 100% inspected and tested before shipment.They are guaranteed for 90 days from the date of shipment against the defects in material or workmanship, when not mis-applied or mis-used. This guarantee is restricted to the replacement of parts or competed product and no allowance will be made for labor or other expense required to repair or replace such defective material, nor shall we be liable for any damages beyond the price of the defective material.

PRICES
Subject to change without notice, but any such price changes shall not apply to orders previously accepted.

DESIGN
We reserve the right to alter specifications and/or dimensions without notice. Any change in current models does not imply that products already in service will be modified to current design.

RETURNED GOODS
No purchases are to be returned after shipment for any reason without prior consent. All returns are subject to a handling charge which is to cover the cost of handling, disassembly, inspection, rework where applicable, restocking and record work.

Complete cylinders are not stocked as units, but are assembled from stock components. Return shipping charges shall be prepaid.

OPERATING TEMPERATURES
Control Line cylinders will operate satisfactorily at ambient temperature form 40 F to 180 F, and intermittent temperatures (1 minute out of 5 minutes) up to 200 F. For operating temperatures at over and above or below this range, please consult our factory.

OPERATING PRESSURES
Control Line cylinders will give good service with ample safety factor in the pressure ranges specified. On hydraulic service, our guarantee is void if there is evidence of surge pressures which could exceed the safety factor at the pressure for which the cylinder was intended.

OPERATING MEDIUM
Unless otherwise specified; Buna N packings will be furnished for mineral oil base hydraulic fluids and for air. If you use phosphate ester base hydraulic fluid or any medium which is not compatible with Buna N Compound, please specify.

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.
