Product Overview: The NUP 307V Cylindrical Roller Bearing
The NUP 307V is a single-row cylindrical roller bearing meticulously engineered for applications requiring high radial load capacity and axial shaft location in both directions. With principal dimensions of 35x80x21mm, this bearing is a key component in our NUP 300 Series. The NUP design features two integral flanges on the outer ring and one integral flange plus a loose flange ring on the inner ring, allowing it to act as a locating bearing. The 'V' suffix indicates a full complement of rollers (no cage), which maximizes the number of rolling elements to provide even greater radial load capacity, making it suitable for heavy-duty, moderate-speed applications. As a premier supplier, we ensure our cylindrical roller bearings meet stringent industry standards for performance and durability.
Key Features of the NUP 307V Bearing
- Bi-Directional Axial Location: The unique flange arrangement securely locates the shaft in both axial directions, simplifying machine design.
- Full Complement Design: A cage-less construction ('V' suffix) allows for a maximum number of rollers, significantly increasing radial load-carrying capacity.
- High Radial Stiffness: The line contact between rollers and raceways provides high stiffness, essential for precision machinery.
- Separable Components: The inner ring, rollers, and outer ring can be mounted separately, simplifying installation and maintenance procedures.
- Durable Construction: Manufactured from high-purity, through-hardened bearing steel for exceptional wear resistance and extended service life.
- Precision Engineering: Designed for low friction and smooth operation under demanding industrial conditions.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling heavy radial loads and ensuring precise alignment.
- Electric Motors: Used as a locating bearing on motor shafts to manage loads and control axial movement.
- Pumps and Compressors: Ensures reliable operation of rotating assemblies under continuous, heavy-duty cycles.
- Construction Machinery: Ideal for use in heavy equipment like excavators and cranes where durability is critical.
- Machine Tool Spindles: Offers the high rigidity required for precision cutting and milling operations.
- Rolling Mills: Withstands the extreme loads and harsh conditions found in metal forming and processing equipment.
- Mechanical Presses: Provides dependable performance in high-load, reciprocating motion applications.
Benefits of Using the NUP 307V Bearing
- Enhanced Load Capacity: The full complement design is purpose-built to handle very high radial loads compared to caged bearings.
