Product Overview: The IR 60*70*40 Inner Ring
The IR 60*70*40 is a high-precision inner ring designed specifically for use with Needle Roller Bearings. With a bore diameter of 60mm, an outer diameter of 70mm, and a width of 40mm, this component serves as a hardened and ground inner raceway. It is essential in applications where the shaft itself cannot be hardened and ground to the necessary specifications to act as a direct raceway for the needle rollers. By using this inner ring, engineers can utilize softer, more economical shaft materials without compromising the performance or lifespan of the bearing assembly.
As part of our comprehensive range of Bearing Accessories and Inner Rings, the IR 60*70*40 is manufactured to strict tolerances, ensuring optimal fit and function. It can be combined with various needle roller and cage assemblies or drawn cup needle roller bearings to create a complete bearing solution capable of handling high radial loads in compact spaces.
Key Features of the IR 60*70*40
- Hardened Raceway Surface: Provides a durable, wear-resistant track for needle rollers, ensuring a long operational life.
- Precision Ground: Manufactured to tight tolerances for high running accuracy and smooth performance.
- High-Quality Bearing Steel: Constructed from premium-grade steel for excellent durability and load-carrying capacity.
- Facilitates Economical Design: Allows for the use of unhardened, standard shafts, reducing overall material and manufacturing costs.
- Chamfered Edges: Features smoothly chamfered edges to simplify mounting and prevent damage to the shaft or bearing during installation.
- Versatile Compatibility: Designed for use with corresponding needle roller and cage assemblies and drawn cup bearings.
Common Applications
- Industrial Gearboxes: Provides a reliable inner raceway for gears mounted on unhardened shafts.
- Automotive Transmissions: Used in transmission systems to support needle roller bearings on various shafts.
- Connecting Rods: Commonly found in the piston and crank ends of connecting rods in two-stroke engines.
- Power Tools: Ensures durability and precision in high-speed applications like drills and saws.
- Pumps and Compressors: Supports rotating components, providing a hardened surface to prevent shaft wear.
- Agricultural Machinery: Ideal for equipment where shafts are subjected to heavy loads and harsh conditions.
- Construction Equipment: Used in pivot points and linkages where space is limited and reliability is critical.
Benefits of Using the IR 60*70*40 Inner Ring
- Prevents Shaft Damage: Protects the shaft from direct contact with the rollers, avoiding wear and the need for costly shaft repairs or replacement.
- Optimizes Bearing Life: Creates an ideal raceway surface, which is crucial for achieving the maximum service life of the needle roller bearing.
- Cost-Effective Solution: Eliminates the need for expensive shaft hardening and grinding processes, simplifying the overall machine design.
- Enables Axial Displacement: Can be configured to allow for axial movement of the shaft relative to the housing, accommodating thermal expansion.
- Improved Performance: Guarantees a smooth and precise rolling surface, leading to lower friction and more efficient operation.
- Simplified Maintenance: In case of wear, only the inner ring needs replacement, which is often easier and cheaper than replacing an entire custom shaft.
