Key Features of INA NKI5/12-TV-XL
High Radial Load Capacity
The needle roller design enables the bearing to carry high radial loads while maintaining a relatively small cross-sectional height.
Compact Light Series Design
As part of the NKI Light Series, the bearing offers an excellent balance between load capacity and space-saving installation requirements.
Axial Displacement Capability
The INA NKI5/12-TV-XL allows axial displacement of up to 1.5 mm. This feature helps compensate for thermal expansion and mounting tolerances, improving system reliability.
Smooth and Efficient Operation
Optimized internal geometry reduces friction and promotes smooth running performance under demanding operating conditions.
Long Service Life
Manufactured to INA's stringent quality standards, the bearing delivers excellent durability, reduced wear, and dependable long-term performance.
Frequently asked questions
What does "NKI" mean in INA NKI5/12-TV-XL?
NKI designates a needle roller bearing with a machined inner ring. Unlike NK bearings (no inner ring), NKI bearings can be mounted directly on an unhardened shaft, making installation easier and reducing shaft preparation costs.
What does the "XL" suffix indicate?
The XL suffix is INA / Schaeffler's designation, indicating the bearings are characterised by a very high load carrying capacity and long rating life.
