Product Overview: The IR 14*17*17 Inner Ring
The IR 14*17*17 is a precision-engineered inner ring designed specifically for use with Needle Roller Bearings. With a bore diameter of 14mm, an outer diameter of 17mm, and a width of 17mm, this component serves as an ideal raceway for needle rollers in applications where the shaft itself cannot be hardened and ground to the required specifications. It allows for the creation of a compact, high-capacity bearing arrangement on standard soft-steel shafts, preventing shaft wear and ensuring optimal bearing performance.
As a key part of our Inner Rings collection, the IR 14*17*17 is manufactured from high-carbon chromium bearing steel, hardened and precision-ground to tight tolerances. This ensures a smooth, durable surface for the needle rollers to run on, minimizing friction and extending the service life of the entire assembly. It is an essential component for any application requiring the benefits of a needle roller bearing on an unhardened shaft.
Key Features of the IR 14*17*17 Inner Ring
- Precision-Ground Raceway: Offers a smooth, optimized surface for needle rollers, ensuring low friction and high rotational accuracy.
- High-Quality Material: Constructed from hardened, high-carbon chromium bearing steel for exceptional durability and wear resistance.
- Standardized Dimensions: Manufactured to industry-standard dimensions (14x17x17mm) for easy integration and interchangeability.
- Facilitates Compact Design: Enables the use of needle roller bearings in space-constrained applications without requiring a specially treated shaft.
- Chamfered Edges: Designed with lead-in chamfers on the sides for simplified mounting and to prevent damage during installation.
- Enhanced Load Capacity: Provides a hard, uniform raceway that helps the bearing assembly achieve its maximum load-carrying potential.
Common Applications
- Automotive Transmissions: Used in gear sets, clutches, and planetary gear systems where space is limited and shafts are not hardened.
- Industrial Gearboxes: Provides reliable raceways for gears and shafts, enhancing performance and longevity.
- Two-Stroke Engines: Commonly found in connecting rods and piston pin assemblies.
- Power Tools: Essential for creating durable bearing arrangements in drills, saws, and grinders.
- Pumps and Compressors: Supports rotating shafts, ensuring efficient and reliable operation.
- Agricultural and Construction Machinery: Used in pivot points and linkages where robust performance is required.
- Office Equipment: Applied in printers, copiers, and other machinery requiring precise rotational movement.
Benefits of Using the IR 14*17*17
- Enables Bearing Use on Soft Shafts: Eliminates the need for costly and time-consuming shaft hardening and grinding processes.
- Protects the Shaft: Prevents direct contact between needle rollers and the shaft, avoiding wear and damage to a critical component.
- Extends Bearing Life: Provides an ideal raceway surface, which is crucial for achieving the full operational life of the needle roller bearing.
- Improves Operational Performance: Reduces friction and ensures smooth, precise rotation, leading to greater machine efficiency.
- Cost-Effective Solution: Offers a more economical alternative to manufacturing custom-hardened shafts.
- Simplified Maintenance: In case of raceway wear, only the inner ring needs replacement, not the entire shaft.
