Cylindrical roller bearing：NU205

Basic Parameters

Type code

• 'NU' indicates cylindrical roller bearings: This is the basic type code of the bearing, clearly indicating that the bearing belongs to the cylindrical roller bearing series. Cylindrical roller bearings have characteristics such as large load-carrying capacity and good rigidity, and are suitable for applications that bear large radial loads and are widely used in many industrial equipments.
  ". Size series code: "

Size series code

• '2' indicates the size series code: Here, '2' represents the combined information of the width series and diameter series of the bearing. In cylindrical roller bearings, different size series correspond to different bearing width and outer diameter size ranges. The '2' series is usually suitable for some application scenarios with medium size and load requirements. It determines the relative size specification of the bearing in the entire bearing series and helps users find bearings of appropriate size according to the specific space and load requirements of the equipment when choosing bearings.
  ". Bore code: "

Bore code

• '05' indicates the inner diameter size: The bore code multiplied by 5 is the inner diameter size of the bearing. So '05' represents an inner diameter of 25mm (05×5 = 25). The inner diameter of the bearing is a key dimension for fitting with the shaft. An accurate inner diameter size is crucial for ensuring a good fit between the bearing and the shaft. A proper fit can ensure that the bearing stably transmits loads during operation, while reducing wear and heat generation and prolonging the service life of the bearing.
  ". Internal structure change code (if any): No special internal structure change code: In the NU205 model, there is no additional letter indicating internal structure changes. If there are special internal structure designs, such as improved roller shapes, cage structures, or other optimized designs, they will be represented by specific letter or number combinations in the model. These internal structure changes may affect the performance characteristics of the bearing, such as load-carrying capacity, speed limit, friction torque, etc., to meet the special needs of different application scenarios.

Structural Characteristics

• Inner ring without flange design: The inner ring of the NU205 bearing has no flange. This unique design allows the rollers to move freely in the axial direction, thus better adapting to changes caused by thermal expansion or shaft deflection. This means that during equipment operation, even in complex working conditions, the bearing can maintain stable performance and effectively reduce additional stress and wear that may be generated due to structural limitations.
• Outer ring with double flanges structure: Correspondingly, the outer ring adopts a double flange structure, providing reliable axial positioning for the rollers and ensuring that the rollers always stay in the correct position during operation to achieve precise rotational movement. This ingenious cooperation between the inner and outer rings not only ensures the high strength and rigidity of the bearing but also enables NU205 to bear a large radial load and provide solid support for your equipment.
• Detachable design: The NU205 bearing is detachable. This characteristic shows great convenience during installation and disassembly. Without the need for complex tools or special equipment, you can easily separate or assemble the inner ring, outer ring, rollers, and cage. This not only saves your time and labor costs but also facilitates the maintenance and repair of equipment, enabling you to respond to possible problems more quickly and ensure the normal operation time of the equipment.

Performance Advantages

• High load-carrying capacity: Thanks to its optimized structural design, the NU205 bearing performs outstandingly in radial load-bearing. It can easily handle various heavy-duty working conditions. Whether in large transmission devices in industrial machinery or at key rotating parts of mechanical equipment, it can stably bear huge radial forces, providing strong support for the efficient operation of equipment and effectively extending the service life of equipment.
• High-speed adaptability: NU205 also performs excellently in high-speed rotation applications. Its special roller design and precise manufacturing process enable the bearing to maintain a low friction coefficient and good lubrication state during high-speed operation, reducing heat generation and energy consumption while ensuring the stability and reliability of operation. This makes it an ideal choice for high-speed equipment such as machine tool spindles and motors, helping to improve the overall performance and production efficiency of equipment.
• High precision and stability: In occasions with extremely high precision requirements, such as precision instruments and numerical control machines, the NU205 bearing stands out with its excellent rotational precision and stability. It can ensure precise positioning and motion control during the operation of equipment, effectively reduce vibration and noise, improve processing precision and product quality, and provide reliable performance support for your high-end equipment.
