Hydraulic Work Support (Flanged Type for Heavy Loads)

Hydraulic Work Support (Flanged and Heavy-Duty)

Product Features

  • This product series features a compact structure, rational design, and long service life. It delivers stable performance at operating pressures ranging from 2 to 7 MPa.
  • The spring force for piston rod extension can be adjusted according to the thickness of different workpieces.
  • The contact force between the piston rod and the workpiece is low (between 0.4–0.8 kgf), making it suitable for various workpieces and minimizing the risk of damage.
  • This product completely eliminates mechanical loads and vibrations during cutting operations, ensuring high precision.
  • Mounting dimensions are compatible with existing market products, allowing for easy replacement and installation.

Hydraulic Work Support (Flanged and Heavy-Duty)

Product Description

Type A: Compressive support (with helical spring). In the initial position, the support head is at the top due to the force of the internal spring. When the workpiece is placed, its weight pushes the support head downward, allowing synchronized movement. Once the workpiece is securely seated in the fixture, the motion stops. Then, hydraulic pressure is applied to lock the cylinder, providing firm support and securing the workpiece in place. Type B: High-pressure support (hydraulic type). In the initial position, the support head is at the lowest position. After the workpiece is placed, hydraulic pressure is applied to the cylinder, causing the support head to move upward. Upon contact with the workpiece, movement stops instantly, and continued pressure locks the support in place. This ensures the support head provides stable, fixed support to secure the workpiece.
