cylindrical roller bearing manufacturers Full complement cylindrical roller bearing is a type of bearing, which means that because there is no cage, it can accommodate as many rollers as possible. Generally used in machinery, most people only know about bearings, but they still don't know much about full complement cylindrical roller bearings. Next, I will introduce the type and basic structure of full complement cylindrical roller bearings to you.

What is a full complement cylindrical roller bearing?

Full complement cylindrical roller bearings are designed to withstand heavy loads. At the same width, this kind of bearing has a very high load carrying capacity compared with the traditional bearing with cage, and the radial section is small, which can save space, but the speed is relatively low. In order to make the bearing work normally, in the case of continuous operation, the bearing must bear a certain minimum load, that is, C/P<25. Otherwise, wear will be aggravated due to insufficient lubrication and high-speed operation. All multi-row cylindrical roller bearings have lubrication grooves and lubrication holes in the outer ring.

Full Complement Cylindrical Roller Bearing Type

1. It has two inner rings. The two inner rings are connected by a clamping ring and cannot be separated. The outer ring has a middle rib, which can bear bidirectional axial load and is used as a positioning bearing. Due to the large distance between the two rows of rollers, it can also withstand overturning moments. There are two retaining grooves on the surface of the outer ring, which can be positioned axially. This type of bearing is equipped with contact sealing rings on both sides and lithium base grease inside, and the operating temperature is limited to -40℃～+80℃. Under certain conditions, this type of bearing does not need maintenance, but when there is water vapor or pollution during operation, and it is often operated at medium or high speed, it must be supplemented with lubrication. When the full complement cylindrical roller bearing is lubricated with oil, the sealing ring needs to be removed and the grease in the bearing should be cleaned.

2. It is a non-sealed bearing. The outer ring is integrally split and fixed together by connecting lock pieces, so the outer ring cannot bear the axial load. The split outer ring is exactly the same, each with a rib. Axial positioning in both directions is possible. The inner ring has three ribs. The outer ring has oil grooves and three lubrication holes. This series of bearings is usually oil lubricated.

3. It is a non-sealed bearing, the outer ring has no rib, and has oil grooves and three lubrication holes. The inner ring has three ribs. A fixed ring is installed in the center of the outer ring between the two rows of rollers, which can prevent the rollers from falling out and keep the bearing as a whole. This series of bearings can allow a certain axial displacement between the shaft and the bearing seat to occur in the bearing. Because it can be used as a floating end bearing.

4. The outer ring has a single rib, and there is a lock ring on the side without the rib, which can be used for one-way positioning of the shaft. The axial clearance "S" inside the bearing ensures the axial positioning of the shaft relative to the bearing box.

5. spherical roller bearing manufacturers are used for extremely heavy load and low speed occasions, with self-locking roller set, even if the inner ring is removed, the rollers will not be scattered, so this type of bearing is easy to install and disassemble, and can withstand one-way axial load , for one-way positioning.
