Product Overview: The RN 306 Cylindrical Roller Bearing Inner Ring
The RN 306 is a precision-engineered inner ring designed specifically for separable Cylindrical Roller Bearings. With key dimensions of 30mm bore diameter, 42.5mm outer raceway diameter, and 19mm width, this component is manufactured to exacting standards for optimal performance. As part of our Inner Rings collection, the RN 306 is designed to be mounted separately from the outer ring and roller assembly (such as an RNU 306). This separable design is highly advantageous in applications requiring simplified mounting and dismounting procedures, especially where interference fits are necessary for both the shaft and the housing.
The RN 306 allows for axial displacement of the shaft relative to the housing, effectively accommodating thermal expansion. It is an essential component in creating complete bearing arrangements like the NU 306 or N 306, providing high radial load-carrying capacity and rigidity. As a trusted supplier of industrial parts, we ensure our RN 306 inner rings meet industry standards for reliability and service life in demanding operational environments.
Key Features of the RN 306 Inner Ring
- Separable Design: Allows the inner ring to be mounted independently of the outer ring and roller assembly, simplifying installation and maintenance.
- High Precision Machining: The raceway is precision-ground to ensure low friction, smooth rotation, and optimal load distribution when paired with a roller set.
- Premium Grade Steel: Constructed from high-purity, hardened bearing steel for exceptional durability, wear resistance, and longevity.
- Axial Displacement: Facilitates axial movement between the shaft and housing, compensating for thermal expansion and preventing induced axial loads.
- Standardized Dimensions: Manufactured to industry-standard dimensions for full interchangeability with corresponding outer ring assemblies.
- Component Versatility: Can be used to complete various cylindrical roller bearing configurations, offering flexibility in machine design.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, allowing for easy assembly within tight-fitting housings.
- Electric Motors: Used to support motor shafts, accommodating thermal growth during operation.
- Pumps and Compressors: Ensures reliable rotation of shafts in demanding industrial fluid and gas handling equipment.
- Machine Tool Spindles: Offers the high precision and rigidity required for accurate machining operations.
- Construction Machinery: Employed in heavy-duty equipment like cranes and excavators where robust, separable bearings are needed.
- Rolling Mills: Supports rollers and shafts under extreme radial loads and high temperatures.
- Automotive Transmissions: Utilized in powertrain systems for its compact design and high performance.
Benefits of Using the RN 306
- Simplified Assembly: The ability to mount components separately makes installation and dismounting significantly easier, reducing downtime.
- Enhanced Reliability: Accommodates shaft expansion, reducing stress on the bearing and surrounding components, leading to a longer machine life.
- Cost-Effective Maintenance: Allows for the replacement of individual components (inner or outer ring assembly) rather than the entire bearing, reducing repair costs.
- Improved Operational Efficiency: The low-friction design contributes to smoother machinery operation and potential energy savings.
- High Radial Load Capacity: When assembled, the bearing provides excellent support for heavy radial loads, ensuring machine stability.
- Design Flexibility: Offers engineers more options for arranging components and managing fits during the machine design process.
