KOYO Double Row Cylindrical Roller Bearing, Inner Dia 75 mm, Outer Dia 115 mm , Width 30 mm, NN3015KC1NA

NN3015KC1NA are a type of rolling element bearing that uses cylindrical rollers to provide high radial load-carrying capacity. They are designed to handle heavy radial loads and moderate axial loads. Here's some information about cylindrical roller bearings: Design and Construction: Inner and Outer Rings: Cylindrical roller bearings consist of an inner ring, an outer ring, and cylindrical rollers. The inner circle is typically mounted on the shaft, while the outer ring is usually placed in a housing or on a stationary component. Cylindrical Rollers: The rolling elements in a cylindrical roller bearing are cylindrical-shaped rollers that run between the inner and outer rings. The raceways on the rings guide them and provide line contact with the rings, distributing the load evenly. Cage: Cylindrical roller bearings often include a pen made of steel, brass, or other materials. The cell holds the rollers, maintaining proper spacing and preventing contact between adjacent rollers. Performance and Advantages: Radial Load Capacity: Cylindrical roller bearings are designed to handle high radial loads. The cylindrical shape of the rollers distributes the load over a larger contact area, resulting in excellent load-carrying capacity. Axial Load Capacity: While primarily designed for radial loads, cylindrical roller bearings can also accommodate moderate axial loads in one or both directions, depending on the bearing's design. Precision and Stability: Cylindrical roller bearings are known for their accuracy and stability, providing smooth and accurate shaft rotation. Misalignment Compensation: Some cylindrical roller bearings are designed to compensate for slight misalignments between the shaft and the housing, allowing for smoother operation. Versatility: Cylindrical roller bearings are used in various applications, including heavy machinery, electric motors, automotive components, and more. Lubrication and Maintenance: Lubrication: Proper lubrication is essential for the performance and longevity of cylindrical roller bearings. Lubricants like grease or oil reduce friction and prevent wear between the rollers and raceways. Maintenance: Regular inspection and maintenance, including lubricant replenishment and cleaning, help ensure optimal performance and extend the bearing's lifespan. When selecting a cylindrical roller bearing, consider load requirements, operating speed, temperature conditions, and desired precision. It is essential to consult the manufacturer's specifications and guidelines to ensure compatibility with your specific application. Proper installation, lubrication, and maintenance practices are crucial for maximising the bearing's performance and service life.
