- Inner ring
- Radial needle roller and cage assembly
- Axial cylindrical roller and cage assemblies
Key Technical Specifications
- Inside Diameter (d): 20mm
- Outside Diameter (D): 68mm
- Width (H): 60mm
- Mounting Configuration: Double direction
- Manufacturer: INA
Unique Features
- Extended and stepped shaft locating washer for enhanced adaptability
- Mounting holes in the outer ring for flexible installation
- Capable of screw mounting on adjacent construction
- Adaptable to radial locating bore installations
Special Design Advantages
The L-type variant is specifically engineered for challenging mounting scenarios, such as:
- Applications where shaft locating washers lack adequate axial support from the shaft shoulder
- Situations with space constraints preventing standard shaft locating washer sealing
- Environments requiring complex load distribution
Recommended Applications
- Industrial machinery with limited mounting space
- Construction and mining equipment
- Precision mechanical engineering systems
- Automotive and aerospace components
- Robotics and motion control mechanisms
The ZARF2068-L-TV offers exceptional performance in demanding environments, providing reliable load support and versatile mounting options for complex engineering challenges.
