Product Overview: The AXK 3047 Thrust Needle Roller Bearing
The AXK 3047 is a high-precision thrust needle roller and cage assembly, designed with principal dimensions of 30x47x2mm. As a key component in our Thrust Needle Roller Bearings collection, this bearing is engineered to handle heavy axial loads in a single direction while maintaining an exceptionally low profile. Its design makes it an ideal solution for applications where radial space is limited, providing a rigid and compact bearing arrangement.
These assemblies consist of a cage that securely guides and retains a large number of needle rollers. For optimal performance, the AXK 3047 requires the adjacent machine components (shaft and housing) to be hardened and ground to serve as raceways. This unique characteristic allows for highly efficient and space-saving designs in a wide range of industrial machinery. For applications where hardening is not feasible, these bearings can be combined with AS series thrust washers.
Key Features of the AXK 3047 Bearing
- High Axial Load Capacity: Engineered to support significant thrust loads in one direction, despite its compact size.
- Low Cross-Section: Its minimal height makes it perfect for applications with tight axial space constraints.
- Rigid and Sturdy Design: The cage assembly provides high rigidity, ensuring stable performance under heavy loads.
- Needle Roller Guidance: The cage precisely guides the needle rollers, minimizing friction and ensuring smooth operation.
- Space-Saving Arrangement: Eliminates the need for separate raceways when used with hardened and ground shaft/housing surfaces.
- Lightweight Construction: Contributes to lower overall machine weight without sacrificing load-bearing capability.
Common Applications of AXK 3047 Bearings
- Automotive Transmissions: Used in gear sets and clutches where axial forces must be managed in a compact space.
- Industrial Gearboxes: Provides axial support for gears and shafts, enhancing durability and efficiency.
- Steering Systems: Ensures smooth and reliable operation in vehicle steering column assemblies.
- Machine Tool Spindles: Supports axial loads in high-precision machine tools, contributing to machining accuracy.
- Pumps and Compressors: Manages axial forces generated by impellers and pistons.
- Robotics and Automation: Ideal for joints and rotating platforms where space is at a premium.
- Two-Stroke Engines: Commonly used to support crankshafts and connecting rods.
