Yale AYS piston plates are accessories for YS cylinders that screw into the piston thread to reduce the surface pressure on the load and prevent the piston from sinking into soft ground. Three sizes: AYS-102 (for YS-10), AYS-152 (for YS-15), and AYS-232 (for YS-23).
Reduces surface pressure on loads and prevents piston sinking
Yale documentation describes the piston plate as screwed into the piston thread of YS cylinders. The plates reduce the surface pressure and prevent the pistons from sinking into the ground. Yale notes that when using a piston plate with a lifting claw, the cylinder must still be supported against the load.
Suitable Applications
Per Yale: reducing surface pressure on loads, preventing piston sinking on soft ground, and protecting the load surface from concentrated point loading.
Cylinders need a matched pump and hose and coupler set — pressure rating and coupler type must agree across the whole circuit before anything is ordered.
Key Features
- Screws Into YS Cylinder Piston Thread: secure mechanical connection.
- Reduces Surface Pressure: wider working face than standard piston.
- Round Plate Design: consistent contact area regardless of piston rotation.
- Three Sizes: matched to YS-10, YS-15, YS-23 piston threads.

Frequently Asked Questions
Q: Can a piston plate be used with a lifting claw?
Yes. Yale shows the AYS-232 piston plate used with the AYS-23 lifting claw. When using a piston plate with a lifting claw, the cylinder must still be supported against the load.
