Cylindrical Roller Bearings Manufacturer

VDObearings supplies a broad scope of cylindrical roller bearings along with custom-engineered bearing solutions for unique applications. Cylindrical Roller Bearing VDObearings carries several variations of cylindrical roller bearings to accommodate many applications. Single row cylindrical rollers can accept relatively higher speeds as opposed to other styles of roller bearings. Double row cylindrical bearings can handle very high radial loads and also transmit axial loads in only one direction.

Common models of cylindrical roller bearings available through Ritbearing include N Series, NU Series, NJ Series, NUP Series, RN Series, RNU Series, NCF18xx.V Series, NCF22xx.V Series, NCF29xx.V Series, NCF30xx.V Series, NJG23xx.V Series, NNCL48xx.V Series, NNCF49xx.V Series, NNCF50xx.V Series, NNF50xx.A.2LSV/ NNF1xx & 2xx.A.2LS.V Series, 81100 Series, 81200 Series

Characteristics of cylindrical roller bearings

1. Roller and raceway for linear contact, radial bearing capacity, suitable for heavy load and shock load.
2. Small friction coefficient, suitable for high speed, close to deep groove ball bearings
3. N type and NU type can be moved axially, if there is a change in the position of the shaft and shell, can be used as a free end support.
4. The processing requirements of the shaft or seat hole are high, and the outer ring axis deflection should be controlled after installation so as not to cause damage.
5. Inner ring or outer ring can be separated, easy to install and disassemble.

Product Type

Cylindrical roller bearings are separated bearings and are very easy to mount and dismount. They can bear large radial loads and are suitable for use in high-speed operation.
Cylindrical roller bearings can be divided into different structures such as single-row, double-row, and multi-row cylindrical roller bearings according to the number of columns of rolling elements.

Single row cylindrical roller bearings(N,NU,NJ,NF,NUP,NFP,NH)

single row cylindrical roller bearings are separable bearings, easy to install and dismantle, both collars can use tight fit, modified contact line between the roller and raceway can reduce stress concentration.

Double row cylindrical roller bearings(NN,NNU,NNF)

Four-row cylindrical roller bearings(FC,FCD)

Four-row cylindrical roller bearings
VDO brand four-row cylindrical roller bearings are mainly used in cold and hot rolling mills and other rolling machinery, the bearings are of a separate structure, and the bearing collar and rolling body assembly can be easily separated, therefore, the cleaning, inspection, or installation and disassembly of the bearings are very convenient.

Applications of cylindrical roller bearings

Due to the special composition of cylindrical roller bearings, they are used in large machinery.

Note the question

In the normal course of use, there will be many problems, especially in terms of vibration and temperature to consider whether there is an abnormal situation, if so please solve it as soon as possible so that your machine can be better rotating use.

The reason for vibration

In normal use, vibration is quite sensitive to bearing damage. Spalling, indentation, rust, cracks, wear, etc. are reflected in bearing vibration measurement. Therefore, by using a special bearing vibration measuring device. can measure the size of the vibration, and the frequency distribution can be inferred from the specific situation of the abnormality. The measured values vary depending on the conditions of use of the bearing or the location of the sensor installation, etc. Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment criteria.

Causes of temperature

The use of high temperatures often indicates that the cylindrical roller bearings have been in abnormal conditions. High temperatures are also harmful to the lubricant of the bearing. Sometimes bearing overheating can be attributed to the bearing lubricant. If the bearing is more than 125 ℃ temperature long-term continuous rotation will reduce bearing life. Causes of high-temperature bearings include insufficient lubrication or lubrication too much, bearing raceway containing impurities, the limit speed too high, and bearing long-term overload operation.

Lubrication bearings

In our machines, bearings are very important parts. The purpose of regular lubrication of bearings is to reduce internal friction and wear, so that your machine runs more smoothly, so that the bearings function properly, to avoid foreign objects in the bearings, to extend the service life of bearing products, then we can lubricate the bearings by manual lubrication, drip lubrication, oil ring lubrication, oil rope lubrication, etc. You can choose the most suitable lubrication method according to the specific load or running speed of the bearings used in your machine. Follow me for the correct lubrication to ensure that the bearings give us good quality. Lubrication Effect

Disassembly bearings

Disassembling the bearing is also a very important step in maintaining the bearing.

When trying to disassemble a bearing, make sure you can do so safely, reducing the risk of injury to yourself or damage to surrounding equipment.
Use a puller and make sure you use the correct size and shape of pliers to properly install the bearing.
Use hydraulic systems and insist on using cylinders designed for bearings.
Never use hot oil or steam to remove bearings, it could damage your machine.

Cleaning bearings

The bearings are washed by rough and fine washing, and the metal mesh frame can be placed at the bottom of the container used.

Rough washing is the removal of grease or adherents in oil with a brush, etc. At this time, if the bearing is rotated in oil, note that the rolling surface will be damaged by foreign matter.
Fine cleaning is to slowly rotate the bearing in oil. Usually, the cleaning agent is water-free neutral diesel oil, or kerosene, as needed sometimes also use warm alkaline liquid. Regardless of which cleaning agent is used, it should be filtered frequently to maintain cleanliness.
Immediately after cleaning, apply anti-rust oil or anti-rust grease to the bearings.
