NB SR-20 Stroke Bush

The NB SR-20 Stroke Bush is a linear and rotational motion bearing designed to accommodate both linear stroke and rotational movement between a shaft and an outer cylinder. Its compact design and ball element mechanism provide smooth motion with low friction.

The SR-20 is a standard type stroke bush for a 20 mm shaft. It features a high-carbon chromium bearing steel outer cylinder and a high-strength alloy retainer designed for wear resistance and smooth operation under high-speed and high-acceleration conditions.
