Product Overview: The NA 4908 Machined Ring Needle Roller Bearing
The NA 4908 bearing is a high-precision component from our NA Series of Machined Ring Bearings. With dimensions of 40x62x22mm (Bore x Outer Diameter x Thickness), this Needle Roller Bearing is engineered for applications requiring high radial load capacity within a minimal space. It features a machined outer ring for enhanced rigidity and comes complete With Inner Ring, making it suitable for use on shafts that are not hardened. The caged needle rollers ensure smooth operation and reliable performance, even at high speeds.
As a specialist in industrial mechanical parts, we ensure our NA 4908 bearings meet stringent quality standards, providing a durable solution for demanding industrial environments. This bearing is an excellent choice for compact machinery designs where space is a critical constraint but load-bearing capability cannot be compromised.
Key Features of the NA 4908 Bearing
- High Radial Load Capacity: Designed with long, thin rollers to support heavy radial loads effectively.
- Compact and Rigid Design: The low cross-sectional height saves space, while the machined outer ring provides superior rigidity and guidance for the rollers.
- Includes Inner Ring: Allows the bearing to be used on standard shafts without the need for special heat treatment or grinding.
- Caged Rollers: The cage guides the needle rollers, reducing friction and heat generation, which permits higher rotational speeds.
- Precision Engineered: Manufactured to tight tolerances to ensure accurate and consistent performance.
- Versatile Application: Suitable for a wide array of industrial machinery where radial space is limited.
Common Applications of NA 4908 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts in a compact footprint.
- Automotive Transmissions: Commonly used in gear systems and powertrain components.
- Pumps and Compressors: Ensures reliable shaft support in various pump and compressor designs.
- Construction Equipment: Ideal for pivot pins and other high-load, oscillating applications in heavy machinery.
- Power Tools: Used in professional-grade electric and pneumatic tools to handle high speeds and loads.
- Printing Presses: Supports rollers and cylinders, ensuring precise and consistent operation.
- Two-Stroke Engines: Frequently used for connecting rods and crankshafts due to their high load capacity and compact size.
Benefits of Using the NA 4908 Bearing
- Space Efficiency: Its small cross-section allows for more compact and lightweight equipment designs.
- Enhanced Durability: The robust construction and high-quality materials lead to a long and reliable service life.
- Improved Performance: Low friction and high rigidity contribute to smoother and more efficient machinery operation.
- Cost-Effective Solution: The inclusion of an inner ring eliminates the expensive need to harden and grind the shaft.
- Reduced Maintenance: High load capacity and durable design minimize wear and reduce the frequency of maintenance and replacement.
- High-Speed Capability: The caged design allows the bearing to operate effectively at higher speeds compared to full complement designs.
