Overview
INA NA2205-2RSR 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.
Key features
- Thick outer ring for track contact
- High radial and shock load capability
- Suitable for cam and rail-following motion
- Sealed or shielded protection options
Typical applications
- Automated transfer systems
- Cam mechanisms
- Conveyor tracks
- Packaging, printing, and textile machines
Selection guidance
Check track shape, outer ring profile, load direction, lubrication/sealing, and yoke or pin dimensions.
