AXRY-NGS bearings are double-direction, screw-on precision bearing units designed for applications that demand high rigidity together with high speed, such as mill-turn tables or vertical lathes.
These bearings absorb axial forces, radial forces and tilting moments without backlash.
AXRY-NGS bearings deliver optimum speed, rigidity and service life within a limited installation space. To reach limiting speeds with long duty cycles, circulating oil cooling on both the inner and outer rings is recommended.
Attention! Three Essentials for High-Speed Axis Operation
- Cooling - Ensure the bearing dissipates heat
- Lubrication - Use an appropriate lubrication method
- Temperature Monitoring - Continuously monitor the bearing temperature
Key Features
High Speed and High Rigidity
Designed for applications requiring both high speed and high rigidity, absorbing axial and radial forces and tilting moments without backlash
Increased Rigidity and Load Ratings
Higher rigidity values and load ratings than the AXRY-ES series, extending service life
Flexible Lubrication Options
Supports axial/radial lubrication, with optional inner-ring lubrication (-SBI) and standard grease pre-lubrication
Integrated Monitoring
Temperature sensor bore as standard on the outer ring; cooling channels can be designed directly into the inner ring
