Rear Flange Mount Hydraulic Cylinder

Welded Rear Flange Mount Hydraulic Cylinder

Cylinder Barrel: The main body that houses the piston and the hydraulic fluid.

Rear Flange: A sturdy, welded plate at the base of the barrel for secure mounting.

Piston: A disc or short cylinder inside the barrel that moves under hydraulic pressure.

Piston Rod: Extends from the piston, through the rod end of the cylinder, to apply force.

Rod Gland: At the front of the cylinder, it contains seals to prevent leaks and wipers to keep out contaminants.

End Cap: Seals the rod end of the barrel and often contains the rod gland.

Seals: Positioned throughout the cylinder to maintain pressure and prevent fluid leakage.

Ports: Channels through which hydraulic fluid enters and exits, controlling the piston’s movement.


Welded rear flange mounted hydraulic cylinders are a rugged piece of mechanical equipment. It is usually cylindrical in shape with a sturdy flange welded to the base for mounting. The exterior is usually coated with industrial grade paint, typically black or grey, but can be customized to any color.

The main function of the cylinders is to convert hydraulic power into linear motion to provide the necessary force for various mechanical operations. And these cylinders are designed for a wide range of working pressures, typically from 1,500 to 5,000 PSI, making them suitable for both light-duty and heavy-duty applications. Stroke lengths vary according to specific task requirements, ensuring versatility for different industrial applications.


Strong Mounting: The welded rear flange provides a solid and stable mount, which is crucial for high-force applications.

Compact Design: This design often allows for a shorter overall length of the cylinder when compared to other mounting styles.

High Force Application: They are capable of handling high-pressure operations, translating into powerful actuation for heavy loads.

Durability: The welding adds to the structural integrity, making these cylinders robust and long-lasting.


Construction Equipment: Often used in bulldozers, excavators, and loaders where strong, stable mounting is necessary.

Industrial Machinery: In presses and injection molding machines that require precise and powerful linear motion.

Automotive Industry: For lifting and positioning heavy components during assembly.

Agricultural Machinery: In tractors and harvesters, where reliable operation under variable conditions is needed.

Welded Rear Flange Mount Hydraulic Cylinder

At the outset, we communicate closely with our customers to understand their specific needs and ensure that each cylinder is designed to meet your expectations. We use high quality materials to ensure the durability and performance of our products. Our engineers rigorously plan the dimensions and tolerances of each component to ensure product accuracy.

During the manufacturing phase, skilled technicians precision-machine each component to ensure stability and strength. The assembly process is thorough, with seals and alignments scrutinized for optimal function. Once assembled, each cylinder undergoes a series of tests, including pressure and leakage tests, to confirm that it meets Topa’s strict quality standards. Only after passing these tests does the cylinder proceed to the finishing stage. During the finishing stage, the cylinders are coated with a protective layer against wear and corrosion to ensure a long service life even under the harshest operating conditions.
