A simple introduction to external hydraulic-cylinder stroke control blocks, sizing, and safe use.
Stroke control blocks are placed on a compatible exposed cylinder rod to limit retraction by a known amount. Multiple block thicknesses allow an operator to adjust the effective travel.
What matters most
Stroke control blocks are placed on a compatible exposed cylinder rod to limit retraction by a known amount. Multiple block thicknesses allow an operator to adjust the effective travel.
Key considerations
- Measure the cylinder rod
- Choose compatible block sizes
- Support equipment before installation
- Keep blocks secure and inspected
- Test the limited range slowly
Put it to work
Use only where the equipment manufacturer permits an external mechanical limit and never place hands near unsupported or pressurized components.
The ANBO approach
ANBO parts support can help identify the appropriate block after the rod diameter, cylinder layout, and intended travel reduction are known.
