AGC series  Servo Hydraulic Cylinders

The AGC servo hydraulic cylinders utilize a design by URANUS, incorporating servo hydraulic cylinder seals.
The cylinder barrel is machined from 42CrMO forged steel, quenched, and tempered.
The inner bore surface is hard chrome plated with a coating thickness of 0.08-0.10 mm and a hardness of Hv800-900.
The piston rod is made of 42CrM0 forged steel, quenched, and tempered. The surface is hard chrome plated with a coating thickness of greater than or equal to 0.08-0.10 mm, and a hardness of Hv800-900.
Factory testing is performed using a testing platform specialized for AGC servo hydraulic cylinders.
Friction performance test; provides dynamic and static friction curves.
Dynamic performance test; provides step response diagrams and closed-loop logarithmic frequency diagrams.
Internal leakage test; measures pressure drop under rated pressure conditions (≤ 0.5 MPa) and provides a pressure holding test diagram.
Testing oil cleanliness; ≥ NAS5 or above
Minimum starting pressure (≤ 0.05 Mpa)
Test pressure; 1.5 times of the rated pressure
Optional displacement sensor types include:
Optional Built-in/ external/ magnetic displacement sensors from MTS, BALLUFF or TR.
SONY magnetic scale sensor, LVDT displacement sensor,
Optional servo valve block, pressure sensor, exhaust and pressure measuring joint, etc. for rodless cavity end;
Optional spherical pad, accordion dust shield, and metal heat shield for piston rod end.
The servo cylinder has a warranty of 1 to 5 years vary by type.
Over 1000 AGC servo hydraulic cylinders have been supplied to customers globally.

Remarks
Instructions		1. This report is a record of the test site and must not be retroactively recorded. 2. The differential cylinder only detects the minimum starting pressure of the rodless chamber; the double-rod cylinder detects the minimum starting pressure of the rod chamber on one side. 3. This report is invalid without the signature and official seal of the company's full-time inspection personnel.
