308 NR
- Commodity name： 308 NR
Design Features of 308NR Bearing
308NR Bearing is a specialized type of rolling-element bearing that features a snap ring groove in the outer ring. 308NR bore dia is 40 mm. Its out dia is 90 mm. 308NR width is 23 mm. This design innovation allows for axial location of the bearing within the housing, reducing the complexity of the machine assembly and saving both time and space.
What Benefits Can 308NR Bearing Provide?
- Enhanced Axial Positioning: The integrated snap ring facilitates secure axial positioning within assemblies, reducing design complexity.
- Increased Load Capacity: Inherits the high radial and moderate axial load capacities from standard deep groove ball bearings.
- Simplified Assembly: The snap ring feature simplifies installation and eliminates the need for additional location components, reducing assembly time.
- Versatility: Available in a variety of seal and shield configurations to suit different operational requirements.
- Cost-Efficiency: By integrating the snap ring feature, 308NR Bearing can reduce the total number of required components, leading to cost savings in mass production.
What Can 308NR Bearing Be Used for?
308NR Bearing is commonly used for applications that require secure axial positioning along with radial load handling. Here are some of the common uses:
- Automotive Assemblies: Particularly in wheel hubs, transmissions, and steering mechanisms.
- Industrial Motors: Used in belt-driven setups where axial security is essential.
- Agricultural Machinery: High-load equipment such as tractors and harvesters.
- Conveyor Systems: Rollers and components requiring secure axial positioning.
- Pumps and Compressors: In settings where both high-load capacity and axial security are required.
