Product Overview: The NA 6901 Machined Needle Roller Bearing
The NA 6901 is a high-precision needle roller bearing featuring a machined outer ring and an inner ring, with principal dimensions of 12x24x13mm. As a key component in our NA Series collection, this bearing is engineered for applications demanding high radial load capacity within a minimal space. Its robust design makes it a superior choice for compact machinery where rigidity and reliability are paramount. Part of the broader Needle Roller Bearings family, the NA 6901 provides a complete bearing solution, as its included inner ring allows it to be used on shafts that are not hardened and ground, simplifying assembly and reducing overall system cost.
Key Features of the NA 6901 Bearing
- High Radial Load Capacity: Designed with a full complement of rollers to support heavy radial loads in a compact footprint.
- Machined Outer Ring: Provides high rigidity and allows for tight press fits into housings, ensuring stable performance.
- Includes Inner Ring: Comes with a hardened and ground inner ring, making it suitable for use with unhardened shafts.
- Low Cross-Section: Its slim profile is ideal for space-constrained applications, allowing for more compact machine designs.
- Separable Components: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and inspection.
- Precision Engineering: Manufactured to strict tolerances for smooth operation, reduced friction, and extended service life.
Common Applications
- Automotive Transmissions: Used in gear sets and shafts where space is limited but load capacity is critical.
- Industrial Gearboxes: Provides robust support for gears and shafts in various industrial reduction units.
- Two-Stroke Engines: Commonly found in connecting rods and crankshafts due to their high performance and small size.
- Power Tools: Ideal for drills, saws, and grinders that require durable bearings in a compact design.
- Printing Machinery: Ensures precise and smooth rotation of rollers and cylinders.
- Agricultural Equipment: Used in various components that experience high loads and require reliable operation.
- Hydraulic Pumps: Supports rotating elements in gear pumps and motors.
Benefits of Using the NA 6901 Bearing
- Space-Saving Design: The low cross-sectional height allows for smaller and lighter machinery.
- Increased Shaft Rigidity: The compact design enables the use of larger, more rigid shaft diameters for a given housing bore.
- Cost-Effective Assembly: Eliminates the need for expensive shaft hardening and finishing processes, lowering manufacturing costs.
- Enhanced Durability: The rigid machined outer ring and high-quality materials ensure long-lasting performance even under heavy loads.
- Simplified Mounting: The separable nature of the bearing facilitates easier and more efficient assembly and maintenance procedures.
- Improved Operational Efficiency: Low friction characteristics contribute to reduced energy consumption and minimal heat generation during operation.
