Description

Model: HDC50-250

Series: HDC

Product Lines: Industrial Tools

  • More compact dimensions, fully optimized outer diameter and body height, greatly reducing installation space requirements
  • Flexible customize production hydraulic cylinders from 50 to 1000 ton capacity and stroke from 50mm to 2000mm.
  • The new structural design uses composite materials to strongly support bearings, 42CrMo alloy quenched and tempered steel, and T-type combined seals to significantly improve the service life and anti-eccentric load ability of the hydraulic cylinder.
  • Quality assurance, each hydraulic cylinder is fully inspected before leaving the factory, full-stroke dynamic load pressure test, and traceable paper inspection report is shipped with the cylinder packaging.
  • Powerful functions, built-in overtravel protection switch, return pressure control safety valve, return overpressure protection safety valve, to avoid failure or safety hazards caused by overtravel use, overpressure use, and oil line connection errors.
  • High temperature paint spraying process provides excellent appearance and anti-corrosion performance.
  • Equipped with CEJN quick thread connector and dust cap.
  • Faster production cycle: digital standard parts and raw materials safe inventory management, hydraulic cylinder delivery cycle 7-14 days.

Think Safety

Manufacturer’s rating of load and stroke are maximum safe limits. Good practice encourages using only 80% of these ratings!

Design

1Equipped with a spherical tilting saddle, it effectively improves the hydraulic cylinder’s ability to resist eccentric loads
2G80 High Strength Lifting Ring
3Alloy quenched and tempered steel piston, surface hard chrome plated, anti-magnetic and corrosion resistant.
4Overtravel protection and return overpressure protection switch, automatic pressure relief in case of overtravel and return overpressure, provide strong safety protection.
5The T-type seal structure provides a minimum of 1.3 times the full-stroke high-pressure life performance.
6The hydraulic cylinder body is made of 42Crmo alloy steel. After heat treatment, the hardness is as high as HRC43, the surface roughness is Ra 0.2, and it has long life and high strength.
7The dust ring prevents external impurities from entering the inner cavity of the cylinder and causing pollution and tool damage.
8Composite material bearing wear rings greatly improve the supporting capacity of the piston and enhance the hydraulic cylinder’s ability to resist eccentric loads.
9Return pressure protection safety valve effectively prevents overpressure caused by pipeline errors.
10Swedish CEJN quick connector and dust cap
11The outer surface of the hydraulic cylinder is treated with high temperature paint to provide excellent appearance and anti-corrosion performance.
12Composite material bearing wear rings can greatly enhance the supporting capacity of the piston and cylinder wall, and enhance the hydraulic oil to increase the hydraulic cylinder’s ability to resist off-center loads and extend its service life.
