Supplier part number:
CST3MT4-125-90-200F
Name: Tie Rod Cylinder With Position Measuring Systems CST3. - MT4 (Trunnions). - Bore Diameter D= 125mm. - With Stroke Length S= 200 mm. Description: Yes, the CST3 series tie-rod cylinder with MT4 (center trunnion) mounting is available with a 125 mm bore and can be configured with a 200 mm stroke.
This is a standard cylinder from the Rexroth range, which has a nominal pressure of 160 bar.
Here are the key specifications and dimensions for this configuration, based on the official Rexroth documentation:
🔧 Key Technical Data (125mm Bore / MT4 Mount)
Mounting Style: MT4 (Center trunnion).
Piston Rod Diameters: For a 125 mm bore, the standard piston rod diameter options are 56 mm, 70 mm, or 90 mm.
Trunnion Diameter: The trunnion pin diameter is 63 mm (QTD f8).
Trunnion Position (XV): A critical dimension, this is the distance from the cylinder base to the center of the trunnion. For a 125mm bore, it is calculated as 132 mm + stroke (for line connection "B"). For your stroke, that is 132 mm + 200 mm = **332 mm**.
Port Thread: The primary line connection is G 1.
Piston Rod Thread (KK): The standard thread for the piston rod for 160 bar operation is M42 x 2 for a 70 or 90 mm rod.
⚙️ Ordering Code Example
Based on the order code structure for the CST3 series, the cylinder would be specified as follows:
CST3MT4/125/[Rod Diameter]/200...
A complete ordering code example from the Rexroth catalog is CST3MT4/125/70/50023X..., demonstrating the configuration pattern.
Note on Ordering: When ordering a trunnion-mount cylinder, you must always specify the "XV" dimension in millimeters in the plain text of your order, as it is freely selectable.
