Single-Acting Hollow Hydraulic Jack
Single-acting hollow hydraulic jacks (Single Acting Hollow Plunger Cylinders - RCH) have specific applications. These jacks, ranging from 13 tons to 95 tons with stroke lengths from 8 mm to 155 mm, are manufactured by Artiman Company based on Enerpac standards. Due to their hollow design, these jacks can apply both tensile and compressive force to a workpiece. To operate this type of jack, a 1-liter, 700-bar manual hydraulic pump along with a hose, gauge, and gauge base—also produced by Artiman Company—is required.
Product Features:
- These jacks are single-acting with spring return.
- The operating pressure of this jack is 700 bar.
- High quality and comparable to foreign models.
- Corrosion and rust resistant.
- Lightweight
- Ergonomic design
- Safe to use
- Comes with a one-year product warranty.
