Raydafon manufactures hydraulic cylinders for construction machinery, agricultural equipment, industrial machinery, and other hydraulic applications. We supply standard and customized cylinders based on required bore diameter, rod diameter, stroke length, mounting type, working pressure, and operating conditions.
Our production process focuses on dimensional accuracy, sealing performance, and reliable operation under repeated hydraulic loads. Hydraulic Cylinder specifications can be confirmed from drawings, samples, equipment requirements, or key dimensions.
Hydraulic Cylinder Construction and Main Parts
A hydraulic cylinder converts hydraulic pressure into linear mechanical movement. Its performance depends on the correct design and fit of several core components.
-
Cylinder Barrel: Provides the pressure chamber for hydraulic oil and guides the piston assembly.
-
Piston: Transfers hydraulic pressure into linear force.
-
Piston Rod: Transmits the cylinder force to the connected machine mechanism.
-
End Cover: Supports and positions the internal components while helping maintain the cylinder structure.
-
Seals: Help prevent hydraulic oil leakage and protect internal components from contamination.
-
Mounting Components: Flanges, trunnions, clevises, spherical joints, and other connection types can be selected according to installation requirements.
How to Measure a Hydraulic Cylinder
Accurate measurements are important when replacing an existing cylinder or requesting a custom Hydraulic Cylinder. The following dimensions should normally be confirmed:
Key Dimensions
-
Bore Diameter: Measure the internal diameter of the cylinder barrel. Measurements should be taken at more than one position to check for variation.
-
Rod Diameter: Measure the piston rod diameter at a clean, unworn section and check it from different directions.
-
Stroke Length: Measure the distance between the fully retracted and fully extended positions.
-
Overall Length: Record the cylinder length in the required reference position, such as fully retracted.
-
Mounting Type: Confirm the connection at both ends, including flange, trunnion, clevis, or spherical mounting.
Information Needed for Cylinder Selection
-
Required bore and rod diameter
-
Stroke length
-
Working pressure and load requirements
-
Mounting dimensions and connection type
-
Hydraulic oil and operating temperature
-
Working environment and movement frequency
Before measuring or removing a cylinder, shut down the equipment, release hydraulic pressure, and clean the cylinder and connection areas. Using calibrated measuring tools also helps reduce dimensional errors.
