This unit provides linear guidance through recirculating ball movement along a shaft with raceways machined on both sides. The design is compact, with a net mass of 85.0 g, allowing continuous linear travel with low friction resistance. The double-sided raceway configuration allows the unit to absorb loads from opposing directions along the guideway, making it suitable for applications requiring precise linear positioning. Its lightweight construction supports installation in systems where reduced moving mass is beneficial, while the recirculating ball design ensures smooth, repeatable motion over the length of the shaft.
