Product Overview: The IR 17*20*20 Inner Ring
The IR 17*20*20 is a precision-engineered inner ring, designed as a critical component for Needle Roller Bearings. With a bore diameter of 17mm, an outer diameter of 20mm, and a width of 20mm, this component provides a hardened and precision-ground raceway for needle rollers in applications where the shaft cannot be used as a direct raceway. It is an essential part for ensuring optimal performance and extending the life of bearing assemblies in various industrial and mechanical systems.
As part of our specialized Inner Rings collection, the IR 17*20*20 allows for the use of needle roller bearings on commercial-grade shafts that are not hardened. This offers a cost-effective and practical solution, eliminating the need for expensive shaft treatments while maintaining high performance standards. This inner ring is designed to work seamlessly with corresponding needle roller bearings, such as the NK 2020, to create a complete and reliable bearing unit.
Key Features of the IR 17*20*20
- Precision Ground Raceway: Features a super-finished surface to ensure smooth, low-friction operation for the needle rollers.
- High Hardness: Manufactured from high-carbon chromium bearing steel and through-hardened for excellent durability and wear resistance.
- Standardized Dimensions: Produced to industry-standard dimensions (17x20x20mm) for interchangeability and easy integration.
- Shaft Protection: Acts as a protective sleeve, preventing wear and damage to the shaft surface.
- Facilitates Axial Displacement: Allows for slight axial movement between the shaft and housing, accommodating thermal expansion.
- Chamfered Edges: Designed with lead-in chamfers on the sides to simplify mounting and prevent damage during installation.
Common Applications
- Automotive Systems: Used in transmissions, universal joints, and engine components like rocker arms and piston pins.
- Industrial Gearboxes: Provides a reliable raceway in compact and high-load gearbox designs.
- Pumps and Compressors: Ensures smooth rotation of shafts in various types of pumps and compressors.
- Power Tools: Essential for the durability and performance of professional-grade drills, saws, and grinders.
- Agricultural Equipment: Found in implements and machinery where robust and reliable bearing solutions are required.
- Construction Machinery: Supports rotating shafts in heavy-duty equipment like excavators and cranes.
- Office Equipment: Used in printers, copiers, and other machines requiring precise rotational movement.
Benefits of Using the IR 17*20*20 Inner Ring
- Cost-Effective Shaft Solution: Eliminates the need for costly hardening and grinding of the shaft, reducing overall manufacturing costs.
- Enhanced Bearing Life: Provides an ideal raceway surface, which significantly extends the operational life of the entire needle roller bearing assembly.
- Simplified Design and Maintenance: Allows for the use of standard, unhardened shafts, simplifying the design process and making replacement easier.
- Improved Rotational Accuracy: The high precision of the inner ring contributes to greater accuracy and stability in rotating machinery.
- Increased Versatility: Enables the use of standard needle roller bearings in a wider range of applications and shaft materials.
- Reduced Downtime: By protecting the shaft from wear, it minimizes the need for shaft repairs or replacements, leading to less machine downtime.
