ESCO Pro-Series 25 Ton Single Acting Ram; 6.25 inch Stroke
Model #10310
The ESCO 25 Ton Single Acting Ram (Model 10310) engineered for high‑force lifting, pushing, and separating in confined or heavy‑duty equipment service scenarios, including bead breaking for earthmover tires.
Manufactured in the USA using globally sourced components and safety‑tested to 125% of rated capacity, it delivers proven reliability and rugged performance.
Ideal for technicians working on earthmovers, heavy machinery, or structural components, the unit can lift rigid or stuck parts, push heavy flanges apart, and break beads where space prevents standard tools.
With a solid steel cylinder body, high‑grade chrome‑plated piston for corrosion resistance, and aluminum‑bronze bearings that reduce wear from off‑center loads, it delivers precise, dependable force.
A removable rubber boot shields threads during transport and storage. Compliant with ANSI/ASME B30.1 standards and backed by a 3‑year warranty, this tool sets the standard for safety and longevity in demanding service environments.
- Compact design ideal for confined spaces behind earthmover wheels.
- Rugged steel construction for long-term durability and strength.
- Chrome-plated piston resists wear and corrosion in harsh conditions.
- Aluminum bronze bearings minimize wear from off-center loads.
- Removable rubber boot protects collar threads during transport and storage.
- Tested to 125% of rated capacity and backed by a 3-year warranty.
