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.
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
Easy installation with uniform dimensions and various mounting options
Reduced size and weight for compact equipment
Fewer maintenance requirements thanks to an easy-to-lubricate design
Configuration Options
SR linear stroke bushings are available in a range of different sizes and configurations to better suit the diverse needs of today’s equipment and component manufacturers. Specific options within the SR product line include:
Standard type SR bushings in a range of sizes from 6-100mm inner contact diameter
SR-UU type bushings with dual-sided seals, available in the same sizes as the standard SR-type products
SR-B linear bushings, for applications requiring load ratings up to 13,700N (dynamic) and 29,400N (dynamic)
SR-BUU type bushings, with double-retainer and double-seal configuration
