Cylindrical Roller Bearings
Compared with ball bearings, double row full complement cylindrical roller bearingshave higher radial load capacity.
The design of cylindrical rolling elements also allows such bearings to accept relatively faster speeds than other forms of roller bearings.
Cylindrical needle roller bearingproduced by VXO, a cylindrical roller bearing types supplier, have many designs, series, and sizes. The main design difference between the cylindrical roller bearing types is as follows.
-The number of roller columns (one, two or four)
-The type of cages (with, without or with special design).
Cylindrical Roller Bearings
Cylindrical Bearing Applications
Cylindrical full complement roller bearingsare suitable for rigid double-supported short shafts, shafts that cause axial displacement due to thermal elongation, and machine parts that need to be separated for installation and disassembly. Different types of cylindrical roller bearings created by THB Bearings, as a professional cylinder roller bearing manufacturer, can meet various demands from customers all over the world. Cylindrical roller bearings are mainly applied in the following industries: large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, steel rolling mills, vibrating screens, lifting and transportation machinery.
Cylindrical Roller Bearing Types
Cylindrical Roller Bearings are dedicated for applications in the most severe operating conditions, including high speeds and heavy radial loads. They are specifically designed to operate in rough environments, such as high temperatures or dirtiness, or high vibrations, etc. The bearing outer rings and inner rings have rolling elements made of either single row lathe cylindrical rollersor ball raceways (1 row & 2 rows) on both sides.
Cylindrical Roller Bearing Features
Roller and raceway are in linear contact or curved contact after modification, with large radial bearing capacity, suitable for bearing heavy loads and impact loads.
The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.
The N type and NU type can move axially, can adapt to the change of the relative position between the shaft and the housing caused by thermal expansion or installation error, and can be used as a free end support.
The processing requirements for the shaft or the seat hole are high, and the relative deflection of the outer ring axis after the cylindrical roller bearing is installed must be strictly controlled to avoid contact stress concentration.
The inner ring or outer ring can be separated for easy installation and disassembly.
Cylindrical Roller Bearing VS Deep Groove Ball Bearing
The main difference between the two types of bearings lies in rolling elements, one is spherical rolling element, the other is cylindrical rolling element. It is precisely because the following differences between them have occurred.
Different bearing capacity: the contact surface of spherical rolling element and cylindrical rolling element is different. The spherical contact surface is a point, while the cylindrical contact surface is a line. Therefore, under the same size, the radial bearing capacity of cylindrical roller bearings is greater than that of deep groove ball bearings.
Different speeds: Because the contact surfaces of the rolling elements of the two bearings are different, their speeds are also different. The larger the contact surface is, the slower the relative speed is. Therefore, deep groove ball bearings with spherical rolling elements have an advantage in speed.
The noise is different: When the speed of the bearing of the same size is the same, the noise of the cylindrical roller bearingis greater than that of the deep groove ball bearing. This is also because the friction caused by the different contact surfaces of the rolling elements of the two bearings is different.
