When choosing between welded and tie rod cylinders, there are several considerations to keep in mind. Both are good cylinder styles, but there are some advantages to choosing welded hydraulic cylinders.
Tie rod cylinders, as the name implies, use rods to connect the two end caps and hold the cylinder body in place. Welded cylinders do not use the external tie rods, but instead, they have a weld connecting the end caps to the body. Both types of hydraulic cylinders can be double or single acting and can be either standard sized or customized to fit specific equipment or systems.
Streamlined Design
The choice of welded hydraulic cylinders means they are a more streamlined cylinder. Without the additional circumference of the tie rods, the welded cylinder can easily fit into smaller, more compact spaces. This becomes increasingly important with higher load capacity cylinders that may have up to 16 or more tie rods.
Durable Seal Package
The design of the welded cylinders provides a very durable seal package. This means less need to maintain the cylinder as well as longer operating even in the most difficult systems. It also extends the life of the seals, which is always a consideration with any hydraulic cylinders.
Ability to Build to Requirements
Customizing welded hydraulic cylinders allows for these cylinders to be used in a wide variety of applications. Generally, tie rod cylinders are used for low to medium capacity types of applications. The welded cylinders can be used for low to high capacity requirements, which gives them an advantage.
While the welded cylinders are typically more expensive, they also tend to have a longer life cycle, lower maintenance, and higher performance capacity. Understanding how these issues impact the specific use of the cylinder is an essential part of making the best choice.
