Low Profile Hardened Way Slide Series
The Low Profile Hardened Way Slide Series provides the strength and durability of a hardened way slide in a lower-height configuration. LHW slides are suited for equipment layouts with limited vertical space or applications requiring a compact slide with strong support.
Low Profile Hardened Way Slide Features
LHW slides use hardened, precision-ground ways to support accurate movement in heavy-load machining environments. The low-profile hardened way slide design helps reduce total assembly height while maintaining stiffness, stability and controlled linear travel.
