Product Overview: The IR 20*24*20 Inner Ring
The IR 20*24*20 is a precision-engineered inner ring designed specifically for use with Needle Roller Bearings. With a bore diameter of 20mm, an outer diameter of 24mm, and a width of 20mm, this component provides a hardened and ground raceway for needle rollers in applications where the shaft cannot be practically or economically hardened and ground to the required specifications. It is an essential part of our Inner Rings collection, offering a cost-effective solution to optimize bearing performance and extend the service life of machinery.
As a key component in many industrial assemblies, the IR 20*24*20 inner ring allows for the use of standard needle roller bearings on commercial-grade shafts, simplifying design and reducing manufacturing costs. It ensures smooth, low-friction operation and enables higher rotational speeds and load capacities than would be possible with an unhardened shaft surface. This makes it indispensable in a wide range of mechanical systems.
Key Features of the IR 20*24*20 Inner Ring
- Precision Ground Raceway: Features a hardened and superfinished outer surface to act as an ideal raceway for needle rollers, reducing friction and wear.
- High-Quality Material: Manufactured from high-carbon chromium bearing steel for exceptional hardness, durability, and fatigue resistance.
- Standardized Dimensions: Produced to strict industry tolerances (20x24x20mm) to ensure interchangeability and a proper fit with compatible needle roller bearings.
- Facilitates Easy Assembly: Designed with lead-in chamfers on the sides to simplify mounting onto shafts and into bearing arrangements.
- Enables Shaft Repair: Can be used to restore the dimensional accuracy of worn or damaged shafts, providing a new, reliable raceway surface.
- Increases Design Flexibility: Allows engineers to use softer, unhardened shaft materials, which can reduce overall production costs.
Common Applications
- Automotive Transmissions: Used in gear sets, clutches, and driveshafts where space is limited and reliable performance is critical.
- Industrial Gearboxes: Provides a durable raceway for gear support bearings, ensuring smooth power transmission.
- Two-Stroke Engines: Commonly found in connecting rod and piston pin applications.
- Power Tools: Essential for the compact and high-speed design of drills, grinders, and saws.
- Pumps and Compressors: Supports rotating components, ensuring efficiency and longevity in demanding conditions.
- Conveyor and Material Handling Systems: Used in rollers and drive mechanisms that require robust and compact bearing solutions.
- Agricultural and Construction Equipment: Provides reliable performance in machinery subject to heavy loads and harsh operating environments.
Benefits of Using the IR 20*24*20 Inner Ring
- Enhanced Bearing Life: Provides an optimal raceway surface, which significantly increases the operational lifespan of the needle roller bearing.
- Cost-Effective Solution: Eliminates the need for expensive shaft hardening and grinding processes, lowering manufacturing costs.
- Improved Machine Performance: Reduces friction and allows for higher rotational speeds, leading to greater operational efficiency.
- Simplified Maintenance: Worn raceways can be quickly replaced by installing a new inner ring, rather than replacing the entire shaft.
- Allows for Larger Shaft Tolerances: The inner ring compensates for variations in shaft diameter, simplifying the manufacturing process.
- Compact and Lightweight Design: Enables the creation of smaller and lighter bearing arrangements compared to other bearing types with similar load capacities.
