Product Overview: The IR 25*30*38.5 Inner Ring
The IR 25*30*38.5 is a high-precision inner ring designed as a crucial component for Needle Roller Bearings. With a bore diameter of 25mm, an outer diameter of 30mm, and a width of 38.5mm, this component is engineered to provide a hardened and precision-ground raceway for needle roller bearings in applications where the shaft itself cannot be used as a raceway. It is an ideal solution when shafts are made of softer materials or when using an unhardened shaft is more economical.
As part of our comprehensive range of Inner Rings, the IR 25*30*38.5 ensures optimal performance and extended service life of the bearing assembly. By creating a suitable running surface, it allows for higher rotational speeds and greater running accuracy. This component is essential for achieving the full potential of needle roller bearings in a wide variety of industrial and mechanical applications.
Key Features of the IR 25*30*38.5
- Hardened Raceway: Manufactured from high-quality bearing steel and hardened to provide a durable, wear-resistant surface.
- Precision Ground: The outer surface is precision-ground to tight tolerances, ensuring smooth operation and minimal friction.
- Standardized Dimensions: Produced to industry-standard dimensions (25x30x38.5mm) for easy integration and interchangeability.
- Chamfered Edges: Features lead-in chamfers on the sides for simplified mounting and to prevent damage during installation.
- Enables Bearing Use on Soft Shafts: Allows for the use of needle roller and cage assemblies or drawn cup bearings on shafts that are not hardened.
Common Applications
- Industrial Gearboxes: Provides a reliable raceway for gears and shafts within compact gearbox designs.
- Automotive Transmissions: Used in transmission systems and drivetrains where space is limited and shafts are not hardened.
- Pumps and Compressors: Ensures smooth rotation and support for components in various types of pumps.
- Power Tools: Essential for high-speed applications in drills, saws, and other handheld power equipment.
- Agricultural Machinery: Supports rotating parts in equipment like combines and balers, offering durability in harsh conditions.
- Two-Stroke Engines: Commonly used for connecting rods and crankshafts due to their high load capacity and compact size.
- Office Equipment: Found in printers, copiers, and other machines requiring precise rotational movement.
Benefits of Using the IR 25*30*38.5 Inner Ring
- Cost-Effective Shaft Design: Eliminates the need for expensive hardening and grinding processes on the main shaft, reducing manufacturing costs.
- Extended Shaft Life: Protects the shaft from wear and tear, as the inner ring serves as the sacrificial running surface.
- Improved Bearing Performance: Provides an optimal raceway surface, leading to lower friction, reduced heat, and longer bearing life.
- Simplified Maintenance: Allows for easy replacement of the inner ring during maintenance without needing to replace the entire shaft.
- Enhanced Rotational Accuracy: The precision-ground surface allows for tighter running clearances and more accurate shaft rotation.
- Versatile Application: Makes it possible to use standard needle roller bearings in a broader range of equipment and shaft materials.
