Linear ball bearing SR series

smoothsteelcompact

The NB STROKE BUSH is a linear and rotational motion mechanism utilizing the rotational motion of ball elements between an outer cylinder and a shaft. It is compact and can withstand high loading. The retainer is made of a light metal alloy with high wear resistance. Smooth motion is achieved under high-speed and high-acceleration conditions. Although the linear motion is limited to a specific stroke length, the combined rotation and stroke motion is achieved with very little frictional resistance. The NB STROKE BUSH can be conveniently used in a variety of applications. NB SR-type linear stroke rotary bushings provide highly accurate linear and rotational motions using a series of precisely machined ball elements located between a shaft and an outer cylinder. Ball elements are retained in a metal alloy retainer to evenly distribute loads while maintaining smooth and precise operation. With their versatile performance, SR stroke bushings are well-suited to a range of applications, including those requiring high-speed and high-acceleration conditions. Features and Benefits At-a-Glance NB linear stroke bushings consist of a high-carbon chromium bearing steel outer cylinder with a precision-ground inner surface, a light metal alloy retainer that keeps ball elements in position, and a stopper ring and inner seal to prevent contamination. While this type of design limits the amount of linear motion stroke, it offers many benefits, such as: -High resistance thanks to heat-treated and ground metal and alloy components that are designed for heavy-duty use -Smooth performance in both high-speed and high-acceleration conditions, with exceptional rigidity and accuracy
