Single Acting Hydraulic Cylinders

Hydraulic Cylinders / Custom Lifting – SVI International – High Capacity Single-Acting Cylinders

Where “well made” and “low cost” can actually be used in the same sentence.

Made in America

SVI International, Inc. is a leading producer of custom fabricated single acting hydraulic cylinders and other steel products for various industries. Our engineering data bank extends back to 1928, meaning our capabilities and design styles for high capacity, large diameter, single-acting hydraulic cylinders are vast.

When you need robust cylinders to get the job done, or a special fabrication project completed and delivered on time, put the SVI team to work for you. Cylinders are available in many stroke lengths and four different diameters to suit your capacity or force requirements.


SVI specializes in Custom Lifting Solutions for many industries and applications:

  • Industrial
  • Material Handling
  • Dispersers / Mixers
  • Steel Mills
  • Lumber Mills
  • Rail Cars, and more.

Designed to stand up to the toughest jobs, each SVI made cylinder is precisely manufactured to retain optimal function and sealing, as well as deliver leak-free load rated performance. Starting with special pressure-rated ASTM A-53 Grade B pipe, polished to a 16 to 32 RMS finish for stronger seals, each component is welded together using thick end-head plate and special welding wire for increased durability.

Once all the components are produced and final assembly is conducted, each cylinder is 100% hydraulically tested for smooth operation and proper performance before shipping.

DUSL vs SUSL Hydraulic Cylinders

DUSL-style cylinders feature two replaceable, glass-filled, nylon wear rings in the upper bearing housing that provide superior load bearing capabilities. The seal and wiper are made from a long lasting, high-performance, thermoset polyurethane compound for ozone and abrasion resistance.

SUSL-style cylinders are made using a cast-iron upper bearing housing that is easily replaceable and capable of resilient performance for many years. The seal and wiper are made from a highly abrasion-resistant buna N compound that has proven itself for decades.

All SVI cylinders can be purchased with a choice of optional fiberglass coating or in your choice of five standard finish colors. Custom colors are available for an additional charge. For harsher applications, optional industrial hard chrome is available for the plunger surface to prolong life and prevent corrosion.
