Product Overview: IR 25*30*30 Needle Bearing Inner Ring
The IR 25*30*30 is a precision-engineered inner ring, designed specifically for use with Needle Roller Bearings. With a bore diameter of 25mm, an outer diameter of 30mm, and a width of 30mm, this component serves as a hardened and ground inner raceway. It is essential in applications where the shaft cannot be hardened and ground to the required specifications to act as a direct raceway for the needle rollers. By using an inner ring, you can ensure optimal bearing performance and extend the service life of both the shaft and the bearing assembly.
As a key component in our Inner Rings collection, the IR 25*30*30 is manufactured to strict industry standards, providing a reliable, cost-effective solution for creating a complete bearing arrangement. It allows for the use of needle roller bearings on commercial-grade shafts, eliminating the need for expensive shaft treatments and precision grinding. This versatility makes it a fundamental part in a wide array of industrial and automotive machinery.
Key Features of the IR 25*30*30 Inner Ring
- Precision Ground Raceway: Features a super-finished surface to ensure smooth, low-friction operation and maximize the life of the needle roller bearing.
- Hardened Bearing Steel: Constructed from high-carbon chromium bearing steel for exceptional hardness, wear resistance, and durability under heavy loads.
- Standardized Dimensions: Manufactured to tight tolerances (25x30x30mm) for a precise fit and interchangeability with corresponding needle roller bearing assemblies.
- Facilitates Shaft Repair: Can be used to restore a worn or damaged shaft to its original dimensions, providing a cost-effective alternative to shaft replacement.
- Simplified Mounting: Designed with lead-in chamfers on the sides to ease installation onto the shaft.
- Enables Bearing Use on Soft Shafts: Allows for the use of high-capacity needle roller bearings on shafts that are not hardened, broadening application possibilities.
Common Applications
- Automotive Transmissions: Used in gear sets, clutches, and driveshafts where space is limited and high radial load capacity is required.
- Industrial Gearboxes: Provides a reliable inner raceway for planetary gears and other compact gear arrangements.
- Two-Stroke Engines: Commonly found in connecting rods and wrist pins due to their compact and high-performance nature.
- Power Tools: Essential in drills, saws, and grinders for supporting shafts and gears in tight spaces.
- Pumps and Compressors: Supports rotating shafts in various types of industrial pumps and compressors.
- Agricultural Machinery: Employed in equipment like balers and harvesters where robust and reliable bearing solutions are critical.
- Textile and Printing Machinery: Used to support rollers and shafts requiring precise rotation and durability.
Benefits of Using the IR 25*30*30
- Extended Shaft Life: Protects the shaft from direct contact with rollers, preventing wear and damage, thus extending its operational life.
- Cost-Effective Solution: Eliminates the need for expensive shaft hardening and grinding processes, reducing overall manufacturing costs.
- Enhanced Bearing Performance: Provides an optimal raceway surface, which improves the performance and longevity of the entire needle roller bearing assembly.
- Simplified Maintenance: In case of raceway wear, only the inner ring needs replacement, not the entire shaft, making repairs quicker and more economical.
- Increased Design Flexibility: Allows engineers to use standard, unhardened shafts in designs that require the high load capacity of needle roller bearings.
- Improved Reliability: Ensures a consistent and reliable bearing performance by providing a hardened, dimensionally stable raceway.
