Hollow Ram Cylinders

Hollow ram cylinders with spring return are versatile hydraulic tools designed for various applications that require both pushing and pulling forces.

These cylinders are characterized by their hollow piston rods, which allow for a threaded rod or cable to pass through, making them ideal for tasks such as tensioning, pulling, or pushing objects.
