CGH2MT4-125-90-300A
Name: Mill Type Cylinder - Double Rod Cylinder(CG) - (BOSCH , Rexroth) Range H2. - CGH2 MT4. - Bore Diameter D=125 mm. - With Stroke Length S=300 mm. Description: Based on the official Bosch Rexroth technical documentation for the CGH2 mill-type cylinder series, here are the specifications and hashtags for your configuration.
🔧 Key Specifications: CGH2-MT4, 125mm Bore, 300mm Stroke
The CGH2 is a robust double-acting cylinder designed for high-pressure industrial applications . The "MT4" mounting style designates a trunnion (pivot) mount, allowing the cylinder to follow the arc of a moving mechanism and compensate for angular misalignment .

📐 Key Mounting Dimensions for MT4 (125mm Bore)
Based on the Rexroth dimension tables , the following critical dimensions apply for a 125 mm bore cylinder with MT4 trunnion mounting:
Dimension Value (mm)
Port Thread (EE) G 1
Piston Rod Thread (KK) M64 x 3 (for 80mm rod)
Y 153
PJ 205
X1 100.5
WA 31
Trunnion Diameter (ØD) 206
🔧 Important Ordering Note
The trunnion position is freely selectable. When ordering, the "XV" dimension (the trunnion position measured from the cylinder base) must always be specified in the plain text in millimeters .
🧾 Ordering Code Reference
The ordering code for your cylinder follows this structure :
CG H2 MT4 / 125 / [Rod Diameter in mm] / 300 A 3X / ...
In this code:
CG = Double-acting cylinder
H2 = Series
MT4 = Mounting style (trunnion mount)
125 = Piston diameter in mm
[Rod Diameter] = e.g., 80 or 90 mm
300 = Stroke length in mm
A = Design principle (head and base flanged)
3X = Component series (30 to 39, unchanged installation and connection dimensions)
