Product Description
The ZARN5090-L-TV is a high-performance INA Needle Roller/Axial Cylindrical Roller Bearing designed for complex mechanical applications requiring precision load support in both radial and axial directions.
Technical Specifications:
- Inside Diameter (d): 50mm
- Outside Diameter (D): 90mm
- Width (H): 78mm
- Configuration: Double direction load capability
Bearing Composition:
This advanced bearing features a comprehensive design including:
- Outer ring with integrated radial and axial raceways
- Extended and stepped shaft locating washers (L-type)
- Inner ring
- Radial needle roller and cage assembly
- Axial cylindrical roller and cage assemblies
Special Features:
- L-type design with extended shaft locating washer
- Ideal for applications with limited axial shaft support
- Suitable for scenarios with constrained sealing options
- Capable of handling simultaneous radial and axial loads
Typical Applications:
- Machine tool spindles
- Precision positioning equipment
- Automotive transmission systems
- Industrial machinery with complex load requirements
- Robotics and automated manufacturing equipment
The extended and stepped shaft locating washer makes this bearing particularly useful in applications where standard shaft shoulders provide inadequate axial support or where space constraints prevent traditional sealing methods.
