Product Description

Active-Power Industries Split Cylindrical Roller Bearing China Factory 30mm-800mm Full Complement Cylindrical Roller Bearing

Product Description

The internal structure of the cylindrical roller bearing adopts rollers arranged in parallel, and spacers or spacers are installed between the rollers, which can prevent the rollers from tilting or friction between the rollers, and effectively prevent the increase of the rotational torque.

According to whether the ring has ribs, it can be divided into single-row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double-row cylindrical roller bearings such as NNU and NN. The bearing has a detachable inner ring and outer ring.

Features
1. The rollers and the raceway are in line contact or trimmed line contact, with large radial bearing capacity, suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
3. N-type and NU-type can move axially, can adapt to changes in the relative position of the shaft and the shell caused by thermal expansion or installation errors, and can be used as free-end supports.
4. The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deviation of the axis of the outer ring must be strictly controlled to avoid contact stress concentration.
5. The inner or outer ring can be separated for easy installation and removal

Application:
Large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, lifting and transporting machinery, etc.

cylindrical roller bearing

What are cylindrical roller bearings, and how are they used in machinery?

Cylindrical roller bearings are a type of rolling element bearing that consists of cylindrical rollers held in place by a cage. They are designed to provide high radial load-carrying capacity and moderate thrust load-carrying capacity. Cylindrical roller bearings have a relatively high stiffness and can accommodate axial displacement between the inner and outer rings.

These bearings are commonly used in various machinery applications due to their specific characteristics and advantages:

  • Radial Load Capacity:

Cylindrical roller bearings can withstand high radial loads, making them suitable for applications where the primary load is radial in nature. The cylindrical rollers distribute the load evenly along their length, reducing stress concentrations and improving load-carrying capacity. This characteristic allows cylindrical roller bearings to support heavy machinery components and handle substantial radial forces.

  • Thrust Load Capacity:

While primarily designed for radial loads, cylindrical roller bearings can also accommodate moderate axial loads. The arrangement of the cylindrical rollers and their contact angle with the raceways enables these bearings to handle limited thrust loads. However, for applications with predominantly axial loads, other types of bearings, such as thrust bearings, may be more suitable.

  • Design Variations:

Cylindrical roller bearings come in various design variations to meet specific application requirements. These variations include different cage designs, such as solid cages or cages made of polymer materials, which offer benefits such as reduced friction and improved lubrication. Additionally, cylindrical roller bearings can have different configurations of the inner and outer ring flanges, such as separable or integral designs, to facilitate installation and maintenance.

  • High-Speed Capability:

Cylindrical roller bearings can operate at high speeds, depending on their design and internal clearance. Factors such as cage material, roller design, and lubrication play a role in determining the maximum allowable speed. Manufacturers provide speed ratings and guidelines to ensure proper selection and operation of cylindrical roller bearings within their speed limits.

  • Application Versatility:

Cylindrical roller bearings find wide applications in various machinery and equipment. They are commonly used in rotating machinery, such as electric motors, gearboxes, pumps, and compressors. Cylindrical roller bearings are also utilized in industries such as automotive, aerospace, construction, and mining, where they support heavy loads and provide rotational motion in critical components.

  • Alignment and Compensation:

Cylindrical roller bearings have the ability to accommodate slight misalignments between the inner and outer rings. This feature allows for easier installation and helps compensate for mounting errors or shaft deflections during operation. The axial displacement capability of cylindrical roller bearings can also assist in thermal expansion or contraction of the shaft and housing.

In summary, cylindrical roller bearings are a type of rolling element bearing that provides high radial load-carrying capacity and moderate thrust load-carrying capacity. They are used in machinery applications where heavy radial loads need to be supported. With their versatility, high-speed capability, and ability to accommodate misalignment, cylindrical roller bearings contribute to the efficient and reliable operation of various types of machinery.
