Oil Hydrostatic Linear Stages

ABTech’s oil hydrostatic linear stages are built for the most demanding applications. The oil hydrostatic fluid film provides high load capacity and extreme stiffness. This allows every stage to provide ultra-smooth motion, sub-micron accuracy, and absolute repeatability. These hydrostatic bearings have no contacting mechanical parts to wear or create drag, allowing for decades of reliable maintenance-free motion.

Our oil hydrostatic stages are commonly used as the core axis in a wide range of machining and grinding applications where medium to high loads are coupled with the need for smooth and repeatable motion. They are ideal as stand-alone units and/or multi-axis assemblies.

Configuration Flexibility

Precision motion comes in many forms and applications, each with its own set of pertinent specifications. The diversity in today’s applications creates many unique requirements, so providing configuration flexibility is integral to our design philosophy. All linear stages can be customized with a variety of options and accessories including motor drives, vacuum carriage top, high-resolution optical encoders, digital readout (DRO) displays, inspection-grade granite surface plates, and more.

In addition to the options and accessories, the material selection of linear stages is a key focus of our applications engineers. For the harsher environments, best accuracy, precision and stability we use hardened stainless-steel air bearing components. This affords forgiveness from minor accidental touchdowns that may result from low oil pressure, excessive loading, or operator error. Our precision motion experts will work closely with you to configure a linear motion solution that will meet your exact needs.
