INA NUTR17-A 支承滚轮 17 × 40 × 21 mm

Overview

INA NUTR17-A Yoke Type Track Roller is an outer-ring rotating roller bearing that follows cam rails or guide tracks. With a thick outer ring and needle or roller elements, it handles localized and shock loads in automation systems, linear guides, and conveyor tracks.

The thick outer ring directly contacts the track, while needle or cylindrical rollers support the internal load. It is mounted in a yoke or fork arrangement for repetitive linear or cam-following motion.

Selection guidance

Check track shape, outer ring profile, load direction, lubrication/sealing, and yoke or pin dimensions.
