Product Overview: The IR 28*32*30 Precision Inner Ring
The IR 28*32*30 is a high-precision inner ring designed as a crucial component for Needle Roller Bearings. With a bore diameter of 28mm, an outer diameter of 32mm, and a width of 30mm, this component serves as a hardened and ground inner raceway. It is specifically used in applications where the shaft itself cannot be practically or economically hardened and ground to the required specifications to act as a direct raceway for the needle rollers. As a key part of our Inner Rings collection, it ensures optimal performance and extends the service life of the bearing assembly.
By providing a perfectly smooth and durable surface, the IR 28*32*30 allows for the use of standard needle roller and cage assemblies or drawn cup bearings on unhardened shafts. This simplifies machine design and maintenance, offering a cost-effective solution without compromising on performance. Our commitment to quality ensures that each inner ring meets stringent industry standards for dimensional accuracy and material integrity, making it a reliable choice for a wide range of industrial and automotive applications.
Key Features of the IR 28*32*30 Inner Ring
- Hardened Raceway Surface: Provides an exceptionally hard and smooth surface for needle rollers to run on, minimizing friction and wear.
- High-Precision Grinding: Manufactured with tight tolerances to ensure accurate shaft fit and uniform load distribution.
- High-Quality Bearing Steel: Constructed from high-carbon chromium steel for excellent durability, load-bearing capacity, and longevity.
- Chamfered Edges: Features smoothly chamfered edges to facilitate easy installation and prevent damage to the shaft or bearing during mounting.
- Cost-Effective Design: Eliminates the need for expensive shaft hardening and grinding processes, reducing overall manufacturing costs.
- Versatile Compatibility: Designed to be used with a variety of needle roller and cage assemblies and drawn cup needle roller bearings.
Common Applications
- Automotive Transmissions: Used in gear sets, clutches, and driveshafts where space is limited and reliability is critical.
- Industrial Gearboxes: Provides a robust inner raceway for gears and shafts in heavy-duty machinery.
- Two-Stroke Engines: Essential for connecting rods (gudgeon/wrist pins) and crankshaft assemblies.
- Power Tools: Ensures smooth and high-speed operation in tools like electric drills, sanders, and grinders.
- Pumps and Compressors: Supports rotating shafts in various types of industrial pumps and compressors.
- Agricultural Equipment: Used in implements and machinery that operate under demanding conditions.
- Conveyor Systems: Provides a durable raceway for rollers and rotating components in material handling equipment.
Benefits of Using the IR 28*32*30 Inner Ring
- Enhanced Bearing Life: Creates an optimal running surface for needle rollers, significantly extending the operational life of the entire bearing assembly.
- Shaft Protection: Protects the shaft from wear and damage, allowing for the use of softer, less expensive shaft materials.
- Simplified Maintenance: In case of raceway wear, only the inner ring needs to be replaced, not the entire shaft, making repairs quicker and more affordable.
- Improved Operational Efficiency: The precision-ground surface reduces friction, leading to smoother operation and lower energy consumption.
- Design Flexibility: Allows engineers more freedom in material selection and shaft design, as specialized hardening is not required.
- Increased Reliability: Guarantees a consistent and high-quality raceway, reducing the risk of premature bearing failure due to shaft imperfections.
