Product Overview: The IR 15*20*23 Inner Ring
The IR 15*20*23 is a high-precision, hardened, and ground inner ring designed specifically for use with Needle Roller Bearings. With a bore diameter of 15mm, an outer diameter of 20mm, and a width of 23mm, this component serves as an ideal inner raceway for needle roller and cage assemblies. It is employed in applications where it is not practical or cost-effective to harden and grind the shaft to the required specifications for a bearing raceway. This inner ring provides a durable, smooth surface that ensures optimal bearing performance and extends the operational life of the assembly.
As a key part of our Inner Rings collection, the IR 15*20*23 allows for the use of standard shafts while achieving the tight tolerances necessary for high-performance bearing applications. It is an essential component for engineers and maintenance professionals looking to create compact, reliable, and efficient bearing arrangements.
Key Features of the IR 15*20*23 Inner Ring
- Hardened Raceway: Manufactured from high-quality bearing steel and case-hardened for exceptional wear resistance and durability.
- Precision Ground Surface: The outer diameter is precision-ground to serve as a smooth and accurate raceway for needle rollers, reducing friction and ensuring smooth rotation.
- Tight Tolerances: Produced to strict dimensional and geometric tolerances for a consistent and reliable fit with both the shaft and the outer needle roller assembly.
- Chamfered Edges: Features lead-in chamfers on the sides to facilitate easy installation and prevent damage to the shaft or bearing during mounting.
- Enables Axial Displacement: Allows for greater axial movement between the shaft and housing compared to many other bearing types.
Common Applications
- Industrial Gearboxes: Used on shafts within gear trains to support needle roller bearings under heavy radial loads.
- Automotive Transmissions: Essential for planetary gear sets, clutches, and other transmission components where space is limited.
- Two-Stroke Engines: Commonly found in connecting rod and piston pin applications.
- Power Tools: Provides robust support for rotating shafts in drills, saws, and grinders.
- Pumps and Compressors: Ensures reliable operation of rotating components in various fluid and air handling equipment.
- Agricultural Machinery: Used in implements and vehicles that require durable and compact bearing solutions.
- Office and Printing Equipment: Supports rollers and shafts in printers, copiers, and other machinery requiring precise rotational movement.
Benefits of Using the IR 15*20*23 Inner Ring
- Cost-Effective Shaft Design: Eliminates the need for expensive hardening and precision grinding of the shaft, allowing for the use of standard commercial shafts.
- Extended Bearing Life: Provides an optimal raceway surface, which maximizes the service life of the needle roller bearing assembly.
- Simplified Assembly: The separate inner ring component makes mounting and dismounting processes more straightforward.
- Enhanced Performance: Ensures low-friction operation and high radial load capacity for the overall bearing arrangement.
- Versatility in Design: Allows engineers to create compact bearing systems in applications where radial space is a constraint.
- Easy Replacement: In case of wear, only the inner ring and needle roller assembly need to be replaced, not the entire shaft, reducing maintenance costs and downtime.
