How to Choose the Right Hydraulic Cylinder Seals:

Hydraulic and pneumatic cylinder performance depends heavily on one critical component that often gets overlooked during early design stages: the sealing system. The right seal choice directly impacts efficiency, reliability, maintenance cycles, and overall operating cost. Understanding how materials, environments, and motion dynamics influence seal performance helps engineers avoid premature failures and maximize equipment uptime.

Hydraulic Cylinder in the Pipe and Steel Industry

In the pipe and steel industry, equipment reliability is not optional. Heavy loads, extreme temperatures, and continuous production demands mean every component must deliver consistent performance. Hydraulic cylinders play a critical role in powering the machines that shape, move, and process steel products, helping manufacturers maintain precision, safety, and uptime.

The History of The Sheffer Corporation

Great companies are rarely built overnight. They are shaped over decades by innovation, adaptability, and an unwillingness to accept “good enough.” Since its founding in the early 1950s, The Sheffer Corporation has followed that exact path, growing from a small engineering firm into a recognized leader in hydraulic cylinder technology.

Hydraulic Cylinders are at the heart of countless industrial, mobile, and manufacturing applications. While they may appear simple from the outside, their performance, reliability, and lifespan depend on a precise combination of internal components working in harmony.

Evaluating Cylinder Replacements and Application-Specific Designs

Hydraulic and pneumatic cylinders are critical components in many industrial systems, and even small deviations in design or performance can impact reliability, safety, and equipment uptime. As machines evolve and operating demands increase, teams are often required to re-evaluate existing cylinder designs or identify suitable replacements that meet current requirements.

When designing a cylinder, it is important to consider how much force will be on the piston rod as the cylinder is extending. If too much compressive force is applied to the piston rod in extend, it will cause it to bend and buckle. Consider a coffee stirrer. When placed between two fingers and pushed on, it very easily bends. Now consider a drinking straw. While it might be longer, it also has a larger diameter, thus when placed between two fingers and pushed on with the same amount of force it does not bend as easily. In the same way piston rods will bend when the force to rod diameter ratio becomes too large. Several factors contribute to the force, and associated cylinder pressure, when this bending will begin to occur. These factors include bore size, rod diameter, mounting style, length of stroke and extra plain rod extension, and even rod material.

Hydraulic and pneumatic cylinders are designed to deliver years of dependable performance—but when a failure happens, it can halt production, reduce efficiency, and create costly downtime. Understanding the most common cylinder issues and how to troubleshoot them is essential for keeping your equipment running smoothly.

In the fast-paced and high-risk oil and gas industry, having reliable, durable equipment is critical to operational success. At the center of many vital systems lies a key component: the Hydraulic Cylinder. Whether it’s land-based drilling, offshore platforms, or refinery systems, hydraulic cylinders provide the power and control needed to operate safely and efficiently.
