Product Overview: The IR 35*40*40 Inner Ring
The IR 35*40*40 is a precision-engineered component designed to serve as the inner raceway for needle roller bearings. With a bore diameter of 35mm, an outer diameter of 40mm, and a width of 40mm, this inner ring is essential for applications where the shaft cannot be hardened and ground to act as a direct raceway. By providing a hardened, high-precision surface, it allows for the use of needle roller bearings on softer shafts, ensuring optimal performance and extending the operational life of the entire assembly.
As a key part of our Needle Roller Bearings and Inner Rings collections, the IR 35*40*40 is manufactured from high-carbon chromium bearing steel. It is through-hardened and precision ground to tight tolerances, which is critical for high-speed or high-load applications. This component is indispensable in compact designs where space is limited but high load-carrying capacity is required.
Key Features of the IR 35*40*40 Inner Ring
- Hardened Raceway Surface: Provides a durable and wear-resistant surface for needle rollers to operate on, prolonging bearing life.
- High-Precision Grinding: Manufactured to exacting dimensional and geometric tolerances for smooth, low-friction operation.
- High-Quality Material: Constructed from high-carbon chromium bearing steel for exceptional strength and longevity.
- Enables Shaft Versatility: Allows for the use of unhardened or softer material shafts, reducing overall manufacturing costs.
- Facilitates Axial Displacement: Can be mounted with a loose fit to permit axial movement of the shaft relative to the housing.
- Compact Design Solution: Ideal for use in conjunction with needle roller bearings in space-constrained applications.
Common Applications
- Industrial Gearboxes: Provides a reliable inner raceway for gear-supporting shafts.
- Automotive Transmissions: Used in clutch assemblies, planetary gear sets, and transmission shafts.
- Two-Stroke Engines: Commonly found in connecting rods and crankshafts.
- Power Tools: Essential for the compact and high-speed mechanisms in drills, saws, and grinders.
- Pumps and Compressors: Supports rotating shafts, ensuring efficiency and reliability.
- Agricultural and Construction Machinery: Used in pivot points, hydraulic pumps, and other heavy-duty equipment.
- Textile and Printing Machinery: Ensures precise rotation of rollers and shafts for consistent production quality.
Benefits of Using the IR 35*40*40
- Cost-Effective Assembly: Eliminates the need for expensive shaft hardening and grinding processes, saving time and money.
- Enhanced Bearing Performance: Guarantees a consistent and optimized raceway surface, leading to improved rotational accuracy and lower friction.
- Increased Durability: Protects the shaft from wear and tear, significantly extending the service life of both the shaft and the bearing.
- Simplified Maintenance: In case of raceway damage, only the inner ring needs replacement, not the entire shaft.
- Design Flexibility: Allows engineers to use standard soft-steel shafts while still achieving the performance of a hardened bearing system.
- Improved Load Distribution: The precision surface ensures that loads are evenly distributed across the needle rollers, preventing premature failure.
