Custom hydraulic cylinder details display

Quanye hydraulic-cylinder offers custom design and manufacturing of hydraulic cylinders. We meet the needs of any application. Below are common hydraulic cylinder components, accessories, and functions. We also have a design department that customizes cylinders to meet all customers’ needs.

Common Base Mounts

Base Mount

The base mount is located at the other end of the cylinder head. It fixes the cylinder to the machine body and is a versatile alternative to welded bases. It makes repairs and maintenance easier.

Welded to the end cover or integrated with the end cover
Precision-machined pin holes and mounting widths to ensure the right machine mounting position
Wear-resistant bushings or bearings are available to reduce wear and increase durability.

Internally Threaded Head Gland

Undergo rigorous quality testing to ensure full fluid manufacturing performance and extreme reliability. These hydraulic cylinder parts secure seals, wipers, and bearings. They ensure the equipment operates as specified.

High-strength ductile iron.
You can fully service the cylinder. Just unscrew the head gland with an adjustable wrench.
Radial screws prevent the head from stripping during operation.

Hydraulic Cylinders Internally Threaded Head Gland

Pistons

The piston in the hydraulic cylinder barrel withstands the force of the hydraulic oil, allowing the cylinder to extend or retract. Pistons are used in single- and double-acting cylinders. They are usually machined with many grooves to keep seals.

High-strength ductile iron
Standard bidirectional piston seals and wear bearings.
Secured with a nylon insert locknut

Rod

The hydraulic cylinder piston rod is on the piston. It passes through the cylinder head. The piston rod connects the cylinder to your equipment. Any required mounting accessories will connect to this component.

Quenched and tempered and high-frequency hardened chrome-plated piston rod. The Mohs hardness of ordinary untempered chrome is about 5. After quenching and tempering, the hardness can reach 28. After high-frequency quenching, it can reach more than 50. Quenching is for surface hardness, not easy to break, not easy to bend. The surface quenching hardness is high and not easy to scratch and bump.
Designed to withstand the maximum tensile and bending loads of the application

Common Rod Mounts

Rod Mount

Rod mounts are used to attach hydraulic cylinders to equipment and machinery. Rod mount cylinder assemblies align and protect cylinders from side loads. They attach to hydraulic cylinder rods. Available in a variety of sizes and configurations to meet your specifications.

Typical welded robustness
Threaded options available for easy maintenance or length adjustments
Bushings or bearings available for increased durability

Tube/Barrel

The hydraulic cylinder barrel contains the piston and rod. This hydraulic cylinder component is closed by a cap on one end and a gland on the other. The barrel, also known as a tube, is built to withstand the harsh conditions and rigors of any application.

Tough 45# steel
Designed with a 1:2 burst safety factor based on material strength and maximum application pressure Standard.

Welded End Cap

Full Hydraulic’s welded end caps provide consistent and reliable welded joints. Made in China, our welded end caps are guaranteed to be of high quality by high-precision methods and a robot arm. They perform well and last in any hydraulic cylinder.

Choose the hydraulic cylinder according to your needs

Single-Acting Hydraulic Cylinders

Custom-made single-acting hydraulic provides power in only one direction. The hydraulic oil exerts pressure on the piston, and the rod moves forward. However, the piston rod needs external force to return to its original position.

Double-Acting Hydraulic Cylinders

Double-acting hydraulic cylinder system is a powerful, advanced system. It provides twice the force and efficiency of a single-cylinder system. Double-acting hydraulic cylinders are commonly used in heavy-duty machinery and equipment

Heavy-Duty Hydraulic Cylinders

Our heavy-duty hydraulic cylinders are high-performing and reliable. They suit many industrial uses. Our heavy-duty hydraulic cylinders work in construction, mining, and agriculture. They ensure heavy machinery and equipment run well and last long. We are committed to providing high-quality products and excellent service.

Light Duty Hydraulic Cylinders

Light Duty Hydraulic Cylinders are designed for applications that require a lower force output. These cylinders are compact in size and are ideal for small-scale hydraulic systems.

Welded Hydraulic Cylinders

Our welded hydraulic cylinder is a high-quality, reliable hydraulic system component. We use advanced welding and high-quality materials to make our products. This ensures excellent performance and durability.

Front Flange Mounted Hydraulic Cylinders

Our front flange mounted hydraulic cylinders are designed for easy installation and provide reliable and efficient performance for a variety of heavy-duty industrial applications. With their durable construction and precision engineering, these cylinders are the ideal choice for demanding hydraulic systems.

HSG Hydraulic Cylinder

The HSG series engineering hydraulic cylinder is a double-acting, single-piston rod hydraulic cylinder. You can match the installation method according to the actual application scenario. There are three types of hydraulic cylinders in engineering. They are based on connecting the cylinder head to the cylinder body. The types are external thread, internal key, and flange connections. They are primarily used in the hydraulics of engineering machinery and agricultural machinery.

MOB hydraulic cylinder

This series is an actuator. It converts linear motion into rotary motion in hydraulic systems. This product has two installation methods: flange and footrest. It has two connection forms: shaft and hole. The unique design of single and double racks suits various work conditions. The optional swing angle makes the product selection more convenient. This product is suitable for metallurgy, mining, and other industries

Hydraulic cylinder material

The main material we use to produce hydraulic cylinders is 45# steel. In addition to 45# steel, other materials can also be customized according to your needs. The material details are in the table below.

cold drawing process

Cold drawing is a process where metal is stretched through a die at room temperature. This technique can effectively improve the mechanical properties of steel tubes, making it very suitable for the manufacture of hydraulic cylinders.

Our cold drawing process is efficient and energy-saving, and can produce steel tubes that meet strict quality standards. These tubes are suitable for a variety of low-carbon and medium-carbon steels and alloy steels, making them able to meet the specific requirements of hydraulic cylinders in different application scenarios.

We look forward to working with you to provide you with high-quality hydraulic solutions!
