Product Overview

The Rectangular Flange Hydraulic Cylinder (Rectangular Flange at Base) is a heavy-duty, fixed-mount hydraulic cylinder designed for high-load structural connections in large industrial equipment.
By integrating a rectangular flange at the cylinder base, the load is transferred evenly to the machine frame, ensuring excellent rigidity, stability, and long-term operational reliability.

During operation, hydraulic pressure drives the piston to generate powerful linear motion, while the base-mounted rectangular flange provides a stable installation reference, effectively preventing misalignment under heavy loads.

6. Selection Tips / Notes

• Rectangular base flange mounting is recommended for large equipment structural connections.

• Confirm that the machine mounting hole pattern matches the flange dimensions before selection.

• For large-bore or high-thrust cylinders, it is strongly recommended to verify flange stress, bolt strength, and overall frame rigidity.

• Long-stroke applications require additional checks for buckling and lateral load stability.
