Product Overview: The IR 12*15*16.5 Inner Ring
The IR 12*15*16.5 is a high-precision inner ring designed specifically for use with Needle Roller Bearings. With a bore diameter of 12mm, an outer diameter of 15mm, and a width of 16.5mm, this component provides a hardened and precision-ground raceway for needle rollers on shafts that have not been hardened. It is an essential part of our Inner Rings collection, offering a practical and economical solution for creating a reliable bearing arrangement without costly shaft treatments.
As a key supplier of industrial mechanical parts, we ensure our IR series inner rings are manufactured to stringent standards. They are indispensable in applications where the shaft cannot serve as a direct raceway due to material softness or surface finish. Using this inner ring allows for greater axial displacement of the shaft relative to the housing and simplifies maintenance and assembly processes.
Key Features of the IR 12*15*16.5
- Precision Ground Raceway: Features a superfinished surface to ensure smooth, low-friction operation and optimal performance of the needle rollers.
- Hardened Bearing Steel: Constructed from high-carbon chromium bearing steel, hardened and tempered for maximum durability and wear resistance.
- Enables Use on Soft Shafts: Allows for the application of needle roller bearings on standard, unhardened shafts, saving on material and treatment costs.
- Chamfered Edges: Designed with lead-in chamfers on both sides to facilitate easy installation and prevent damage during mounting.
- Tight Tolerances: Manufactured to precise dimensional and geometric tolerances to ensure a proper fit and reliable operation.
- Corrosion Resistance: Treated to resist corrosion, ensuring a long service life even in moderately challenging environments.
Common Applications
- Industrial Gearboxes: Provides a hardened raceway for gear support shafts, enhancing reliability and performance.
- Automotive Transmissions: Used in transmission systems, clutches, and driveshafts where space is limited and reliability is critical.
- Two-Stroke Engines: Commonly found in connecting rods for piston pins and crankpins.
- Power Tools: Essential for compact, high-load applications in drills, saws, and grinders.
- Pumps and Compressors: Supports rotating shafts, ensuring efficient operation and longevity.
- Agricultural Machinery: Employed in various implements and vehicles that operate under heavy loads and harsh conditions.
- Office Equipment: Used in printers, copiers, and other machinery requiring precise rotational movement.
Benefits of Using the IR 12*15*16.5 Inner Ring
- Cost-Effective Design: Eliminates the need for expensive hardening and grinding of the shaft, reducing overall manufacturing costs.
- Extended Shaft Life: Protects the shaft from wear and damage, as the inner ring serves as the sacrificial rolling surface.
- Simplified Maintenance: Allows for easy replacement of the bearing surface (the inner ring) without needing to replace or repair the entire shaft.
- Improved Bearing Performance: Provides an optimal raceway surface, leading to a longer service life and better performance from the needle roller bearing assembly.
- Design Flexibility: Enables the use of larger shaft tolerances and allows for axial expansion and contraction.
- Increased Load Capacity: Creates a robust bearing arrangement capable of handling high radial loads within a compact design.
