Product Overview: The IR 30*35*40 Inner Ring
The IR 30*35*40 is a high-precision inner ring designed specifically for use with needle roller bearings. With a bore diameter of 30mm, an outer diameter of 35mm, and a width of 40mm, this component serves as a hardened and precision-ground inner raceway. It is an essential part of our Needle Roller Bearings collection, ideal for applications where the shaft cannot be hardened and ground to serve as a raceway itself. By providing an optimal running surface, this inner ring ensures the proper function and extends the service life of the entire bearing assembly.
As a key component in many mechanical systems, the IR 30*35*40 allows for the use of softer, more economical shaft materials without compromising the performance of the needle roller bearing. Our Inner Rings are manufactured to strict industry standards to guarantee dimensional accuracy and reliable performance in demanding industrial and automotive applications.
Key Features of the IR 30*35*40
- Precision-Ground Raceway: Offers a smooth, uniform surface for needle rollers to travel on, reducing friction and ensuring optimal load distribution.
- High-Quality Bearing Steel: Constructed from hardened, high-carbon chromium steel for exceptional durability and resistance to wear and fatigue.
- Hardened Surface: Provides the necessary hardness to withstand the high contact stresses of needle rollers, preventing premature failure.
- Standardized Dimensions: Manufactured to precise industrial standards (30x35x40mm) for easy integration and interchangeability with compatible bearing assemblies.
- Chamfered Edges: Features smoothly chamfered edges to facilitate easier mounting and prevent damage to the shaft or bearing during installation.
Common Applications
- Automotive Transmissions: Used in gear sets, clutches, and planetary gear assemblies where space is limited and reliability is critical.
- Industrial Gearboxes: Provides a robust inner raceway for gear support shafts, ensuring smooth power transmission.
- Two-Stroke Engines: Commonly found in connecting rods (small end and big end) and crankshaft applications.
- Pumps and Compressors: Supports rotating shafts, providing a durable surface for needle roller bearings in high-speed conditions.
- Power Tools: Essential in the construction of drills, sanders, and other handheld equipment requiring compact and reliable bearing solutions.
- Universal Joints: Used in driveshafts to provide a hardened path for needle rollers.
- Material Handling Equipment: Applied in conveyor rollers and lifting mechanisms where shafts are subjected to heavy loads.
Benefits of Using the IR 30*35*40 Inner Ring
- Enables Softer Shaft Materials: Allows designers to use unhardened shafts, reducing overall material and manufacturing costs.
- Extends Shaft Service Life: Protects the shaft surface from direct contact with rolling elements, preventing wear and eliminating the need for costly shaft repairs or replacements.
- Cost-Effective Repair Solution: A worn or damaged shaft can be ground down and fitted with an inner ring, restoring it to operational condition for a fraction of the cost of a new shaft.
- Optimizes Bearing Performance: Creates an ideal raceway with the correct hardness and surface finish, maximizing the performance and lifespan of the needle roller bearing.
- Facilitates Compact Designs: Allows for smaller, more compact machinery designs by enabling the use of through-shafts without special heat treatment.
- Simplifies Maintenance: Can be easily replaced during overhauls, reducing machinery downtime and simplifying the maintenance process.
