Supplier part number:
CST3ME5-80-45-100F1
Name: Tie Rod Cylinder With Position Measuring Systems CST3 - ME5. - Bore Diameter D= 80mm. - With Stroke Length S= 100 mm. Description: Based on the available technical documentation for the Bosch Rexroth CST3 series, a cylinder configuration of CST3-ME5 with an 80 mm bore and 100 mm stroke is a standard and valid variant .
Below is a summary of the key specifications and details relevant to this configuration.
📊 Key Technical Specifications
General Data
Series: CST3 - Differential cylinder with integrated position measuring system .
Mounting Style (ME5): Rectangular flange at the cylinder head .
Nominal Pressure: 160 bar .
Position Measuring System: Magnetostrictive principle, providing non-contact absolute measurement .
For Your 80 mm Bore Configuration
Bore Diameter (ØAL): 80 mm .
Stroke Length (S): 100 mm. (Note: The catalog states a stroke tolerance of 0 to +2 mm for strokes up to 1250 mm) .
Standard Piston Rod Diameter (ØMM): For an 80 mm bore, the standard rod diameter options are 36 mm, 45 mm, or 56 mm . You will need to specify this in the full ordering code.
📏 Performance & Force Data (at 160 bar)
The following theoretical forces are applicable for the 80mm bore cylinder:
Piston Rod Diameter (ØMM) Pushing Force (kN) Pulling Force (kN)
36 mm 80.42 64.14
45 mm 80.42 54.98
56 mm 80.42 41.02
Note on Force: These are theoretical values, not accounting for efficiency losses .
✍️ Ordering Code Structure Example
Based on the Rexroth ordering code, an example for your cylinder would be formatted as follows :
CST3ME5/80/[Rod Diameter in mm]/100F...
In this code:
CST3 is the base series.
ME5 is the mounting type.
80 is the bore diameter.
[Rod Diameter in mm] must be replaced with your chosen rod size (e.g., 36, 45, or 56).
100 is the stroke length in millimeters.
You would need to complete the code with other options like piston rod end type, seal version, and the specific output for the measuring system (e.g., analog 4-20mA, 0-10V, or digital SSI) .
If you know the specific piston rod diameter or the required output sig
