Overview
NTN AS204 Radial Insert Ball Bearing is an easy-mount ball bearing used in housing units or directly fixed on shafts. Based on deep groove ball bearing geometry, it adds locking devices and seals to simplify maintenance in agricultural machines, conveyors, fans, and handling equipment.
A spherical outer ring and shaft-locking device allow the bearing to compensate for static misalignment when combined with a matching housing. Sealed and lubricated variants are suitable for dusty or wet operating environments.
Key features
- Easy shaft mounting with locking device
- Misalignment compensation with matched housings
- Sealed designs for contaminated environments
- Simple replacement and maintenance
Typical applications
- Conveyor rollers
- Agricultural and food machinery
- Fans and blowers
- Packaging and handling equipment
Selection guidance
Check locking method, housing compatibility, seal design, lubrication, contamination level, and load condition.
