Parker’s SP Series of the crossed roller slide bearing system is composed of two rows of rollers. Each roller is alternately crossed at 90° with the next and captured in “V” grooves, located on the base and top. Since rollers provide a larger (line) contact surface than ball bearings, a crossed roller slide has higher load carrying capability than a ball slide of comparable size.

The SP Series features end plates for positioning, making them ideal for factory automation applications. The SP offers excellent precision, smooth motion, and a long life in a compact footprint.
