To maximize
cylinder longevity in production applications, we recommend taking a
moment to review the following information.
|
|
| |
1. |
Minimize Internal
Contamination |
|
| |
|
- Minimize accumulation of solid
contaminates through design considerations and scheduled die
maintenance.
- Minimize cylinder exposure to fluid
accumulation through proper drainage methods incorporated during
design.
- Rod wiper lip pressure is a critical
factor in preventing ingestion of foreign material. Inspection of rod
wipers on new cylinders, as well as production cylinders should reveal
no gaps between the cylinder rod and rod wiper. If gaps are found to
exist, return cylinders to manufacturer for evaluation.

2. |
Eliminate
All Side Loading |
|
| |
|
- To prevent premature cylinder
failure from side loading, cylinder alignment must be perpendicular to
the contact surface and parallel to the die action.
|
|
| |
3. |
Prevent
Free Acceleration |
|
| |
|
- Uncontrolled acceleration will
damage a cylinder. To prevent this situation, we recommend pre-loading
the cylinders whenever possible.
|
|
| |
4. |
Installation in Pockets |
|
| |
|
- It is critical to ensure that
pockets are machined to the recommended tolerances for each series
cylinder and that all pocket bottoms are flat with enough relief in
the corners to eliminate any interference during installation.
- Make sure that holes drilled for
venting or draining the die are located in the pocket side wall, near
the bottom.
