Tech Talks: Manufacturing & Prototyping

Hydraulic Cylinders and the Search for the Perfect Seal


Large-scale manufacturers, such as those in the agricultural and construction industries, are tasked with finding a balance between the cost and performance of their hydraulic cylinders. This Tech Talk explains how to achieve that goal by optimizing advanced sealing technology. In the process, material and component costs can be reduced by as much as 40 percent.

An innovative seal-first approach can be used to achieve the proper balance between cost and performance. Three premium sealing materials help manufacturers use non-honed surface finishes, reduce the number of seals in the system, increase performance, and reduce manufacturing time.

The Tech Talk also examines the importance of optimizing cylinder design while maintaining maximum application performance, as well as how engineered seals that are correctly matched to a cylinder ensure long-term protection against leaks, contamination, and excessive wear.
