2HB (AccuSlide) Linear Units

2HB (AccuSlide) Ball Screw Unit, Ball Guided

Thomson's 2HB (AccuSlide) is a high performance slide table based on Thomson's continuously supported, ProfileRail system using square rail technology. The units are designed to absorb extremely high load torques and offer superior performance life in difficult applications.
