When it comes to industrial lifting, pushing, pulling, or holding, Simplex Hydraulic Cylinders are the go-to choice for professionals who demand performance, reliability, and safety. Built for high-pressure applications and engineered for durability, Simplex hydraulic cylinders are a core component in countless industries across the United States.

In this article, we’ll explore what Simplex hydraulic cylinders are, how they are used, the difference between hydraulic and mechanical cylinders, the types of accessories available, which industries use them, and some surprising facts that highlight their versatility and power.

What Are Simplex Hydraulic Cylinders?

Simplex hydraulic cylinders are high-pressure industrial tools designed to produce linear force through hydraulic pressure. Available in a wide range of sizes and configurations, they are commonly used in applications that require lifting heavy loads, applying force, or holding components in place.

These cylinders operate using hydraulic fluid, which is pumped into the cylinder to extend or retract the piston rod. The force generated is directly proportional to the pressure applied, allowing Simplex cylinders to generate forces from a few tons to over 200 tons in some models.

Are They Hydraulic or Mechanical?

Simplex cylinders are fully hydraulic—they rely on hydraulic pumps and fluid pressure to generate force. While there are mechanical jacks and screw-type lifting devices on the market, the cylinders discussed here are entirely hydraulic, offering superior force, precision, and compact design compared to their mechanical counterparts.

Simplex does manufacture mechanical jacks in other categories, but hydraulic cylinders stand alone in their category as fluid-powered devices.

Where and How Are Simplex Hydraulic Cylinders Used?

These powerful cylinders are used in numerous field and shop applications:

• Construction: Lifting and supporting bridges, buildings, precast concrete sections.
• Railroads: Track maintenance, realignment, and tie installation.
• Mining & Heavy Industry: Machinery installation, equipment shifting.
• Energy: Supporting transformers, pipe adjustments, and power plant maintenance.
• Manufacturing: Industrial pressing, forming, die work, and component alignment.
• Shipbuilding & Marine: Dock lifting, hull support, and alignment tasks.

They are often deployed as part of a larger lifting or positioning system and can be used horizontally or vertically depending on the cylinder type.

Accessories for Simplex Hydraulic Cylinders

Simplex offers a variety of accessories to maximize the flexibility and functionality of their hydraulic cylinders:

• Hydraulic Pumps: Hand, air, or electric pumps provide the necessary fluid pressure.
• Hoses and Fittings: High-pressure rated hydraulic hoses with quick-connect couplers.
• Pressure Gauges: Monitor system pressure for safety and control.
• Tilt Saddles: Allow better contact and self-alignment with load surfaces.
• Locking Collars: Secure loads in place for extended support.
• Extension Tubes: Increase the effective reach of the piston rod.

Choosing the right accessories ensures safe, efficient operation in the field.
