Product Description

Product Description

  Cylindrical roller bearings are a type of rolling-element bearing that uses cylindrical rollers to maintain the separation between the moving parts of the bearing. These bearings are designed to handle high radial loads and moderate axial loads. Here are some key features and applications of cylindrical roller bearings:

Key Features:

1. High Radial Load Capacity: Cylindrical roller bearings are designed to support high radial loads due to the line contact between the rollers and the raceways.

2. Moderate Axial Load Capacity: They can handle moderate axial loads, especially if the bearing has flanges on the inner or outer ring.

3. Low Friction: The rolling elements reduce friction compared to sliding contact bearings, leading to higher efficiency and lower heat generation.

4. High Speed Capability: These bearings can operate at high speeds, making them suitable for various high-speed applications.

5. Separable Design: Many cylindrical roller bearings have separable components, which makes installation, disassembly, and maintenance easier.

Company Profile

 Zhejiang Judong Bearings Co., Ltd., established in [2016], is located in Zhejiang Province, China. We are a professional manufacturer and supplier of a wide range of bearing products. Our bearings are widely used in industries such as machinery manufacturing, automotive, electronics, home appliances, and industrial automation.

In the operation system of industrial machinery, cylindrical roller bearings, with their unique designs and excellent performances, have become indispensable key components for numerous devices. Their remarkable advantages are mainly reflected in the following aspects:

1. Powerful Load - bearing Capacity

 

Cylindrical roller bearings adopt a design where the rollers have line contact with the raceways. Compared with bearings with point contact, the contact area is significantly increased. This endows them with extremely outstanding radial load - bearing capacity, enabling them to easily handle heavy loads and impact loads. In large - scale mechanical equipment in industries such as steel and mining, in the face of huge pressure and frequent impacts, cylindrical roller bearings, with their powerful load - bearing capacity, ensure the stable operation of the equipment and serve as a solid guarantee for production.

2. High - speed Operation Adaptability

 

The friction between the rolling elements and the ring ribs is relatively small. This allows cylindrical roller bearings to effectively reduce energy consumption and heat generation during high - speed rotation. Their limiting speeds are close to those of deep - groove ball bearings. They are especially suitable for equipment with high - speed requirements, such as high - speed machine tools and aero - engines, providing strong support for the efficient operation of the equipment.

3. Excellent Precision and Stability

 

Their precise structures and high - precision processing techniques enable them to maintain high rotational accuracy even when bearing eccentric loads, ensuring the stable operation of the equipment. In fields with extremely high precision requirements, such as precision instruments and optical equipment, this characteristic of cylindrical roller bearings is of crucial importance. It can guarantee the accurate operation of the equipment and the production of high - precision products.

4. Good Axial Displacement Adaptability

 

N - type and NU - type cylindrical roller bearings can move axially and can skillfully adapt to the changes in the relative positions of the shaft and the housing caused by thermal expansion or installation errors. When used as free - end supports, they can effectively avoid equipment failures caused by displacement problems, greatly enhancing the reliability and service life of the equipment.

5. Convenient Installation and Disassembly

 

They belong to separable bearings, and the inner ring or outer ring can be separated. During the installation, debugging, and maintenance of equipment, technicians can easily operate, replace the damaged components individually without the need for overall replacement. This not only reduces the maintenance cost but also greatly shortens the equipment downtime and improves the equipment availability.

6. Long Service Life and Low Maintenance Cost

 

The rolling elements and raceways are made of high - quality materials and processed through advanced heat - treatment techniques, endowing them with good durability and a long service life. At the same time, they only need regular simple lubrication and inspection to ensure normal operation, with relatively low maintenance costs, saving enterprises a large amount of manpower, material resources, and financial resources.

7. Flexible Design Adaptability

 

According to different application requirements, different designs, materials, and dimensions can be selected. Whether in automotive engines, ship propulsion systems, or industrial automation equipment, suitable cylindrical roller bearings can be found. They have strong adaptability and flexibility, meeting the diverse needs of industrial production.
