Product detailed description
Bearing NKX 12-Z-XL-X-LIFE INA
The NKX 12-Z-XL-X-LIFE INA is a high-quality needle roller bearing designed for demanding applications requiring compact design and reliable performance. Manufactured by INA, a trusted name in the bearing industry, this bearing offers exceptional durability and precision engineering tailored to meet the rigorous standards of modern machinery.
This bearing belongs to the NKX series, known for their needle roller cages with an extended inner ring and a sealing shield on one side (denoted by the "Z" in the designation). The "XL" indicates an extra-long inner ring, providing additional support and stability for the shaft. The "X-LIFE" technology enhances the bearing’s fatigue life and reduces friction, making it suitable for applications with high load and speed requirements.
Key features of the NKX 12-Z-XL-X-LIFE INA include:
- Needle roller bearing with a full complement of rollers for high radial load capacity
- Shielded on one side for protection against contamination and to retain lubrication
- Extended inner ring for increased rigidity and better shaft support
- X-LIFE performance for longer service life and improved reliability
- Compact design suitable for space-constrained assemblies
This bearing is typically used in automotive transmissions, industrial gearboxes, machine tool spindles, and other mechanical systems where precise radial guidance and high load support are critical. The combination of the sealing shield and X-LIFE technology ensures enhanced protection and durability, reducing maintenance requirements and downtime.
Unfortunately, specific dimensions for this particular model are not available in common catalogs, but based on INA’s NKX series standards, similar bearings often accommodate shaft diameters around 12 mm, aligning with the “12” in the product code. For exact dimensions and mounting recommendations, please consult the official INA technical documentation or contact an authorized distributor.
