CST3MT4-80-56-100F1
Name: Tie Rod Cylinder With Position Measuring Systems CST3 - MT4. - Bore Diameter D= 80mm. - With Stroke Length S= 100 mm. Description: Based on the Bosch Rexroth technical documentation, here are the details for your CST3-MT4 tie rod cylinder with an 80 mm bore and 100 mm stroke, along with suggested hashtags.
🔧 Key Specification: Mounting Style MT4
The "MT4" in the ordering code designates a center trunnion (pivot pin) mounting style. This mounting type allows the cylinder body to pivot around a fixed pin, which helps to absorb misalignment and reduce side loads on the piston rod and seals. The trunnion position is freely selectable; when ordering, the "XV" dimension must always be specified in mm in the clear text.
🧾 Ordering Code Example
Based on the Rexroth ordering system, your cylinder configuration would be formatted as follows:
CST3MT4/80/[Rod Diameter in mm]/100F...
In this code:
CST3 is the base series for a differential cylinder with an integrated position measuring system.
MT4 is the mounting type (center trunnion).
80 is the bore diameter in mm (ØAL).
[Rod Diameter in mm] needs to be replaced with your chosen standard rod size. For an 80mm bore, standard options are typically 36mm, 45mm, or 56mm.
100 is the stroke length in mm (S).
📐 Additional Specifications for Your Configuration
Technical Data
Nominal Pressure: 160 bar (16 MPa).
Mounting Feature: The center trunnion mount allows the cylinder body to pivot around a fixed pin, absorbing misalignment and reducing side loads on the piston rod and seals.
Performance Force Data (at 160 bar)
The theoretical forces for your cylinder depend on the selected piston rod diameter:
36mm rod: 80.42 kN pushing / 64.14 kN pulling.
45mm rod: 80.42 kN pushing / 54.98 kN pulling.
56mm rod: 80.42 kN pushing / 41.02 kN pulling.
Note: These are theoretical values and do not account for efficiency losses.
