NB Corporation of America is the North American entity of Nippon Bearing Co., Ltd., a Japan-based manufacturer of linear motion bearing products including ball splines, cross roller guides, linear bushings, linear actuators, shafts, and slide screws.
Ball spline shafts and nuts that transfer linear motion and torque via recirculating ball elements between a grooved shaft and spline nut, used in SCARA robots and assembly equipment.
Cross roller linear guides, slide tables, and curved gonio-way guides using non-recirculating precision crossed rollers, providing low-friction, low-noise motion for optical and measurement equipment.
Linear ball bushings, including the standard Slide Bush and the high-load TOPBALL series, used in transportation equipment, food processing equipment, and semiconductor equipment.
Single-axis linear actuators that integrate a slide guide and precision ball screw into a compact positioning stage, using a U-shaped guide rail and slide block design.
Precision-machined and heat-treated straight shafts used as mechanical components for linear and rotational motion in general machinery.
Friction-driven screws that convert rotational motion into linear transport motion via friction between radial ball bearings and a shaft. Intended for material transport, not precision positioning.
