NB SR-20 Stroke Bush

The NB SR-20 is a stroke bush designed to provide combined linear and rotational motion using recirculating ball elements. With a compact cylindrical design, it delivers smooth, low-friction movement while supporting high-speed and high-precision operation. Engineered with a durable outer cylinder and lightweight retainer, the SR-20 offers reliable performance in applications requiring both sliding and rotational motion within a limited stroke length.
