by 
with the raceway and has large radial bearing capacity. Cylindrical Roller Bearings It is suitable for bearing heavy load and impact load.
suitable for high speed, the limit speed is close to the deep groove ball bearing.
can move axially, can adapt to the change of relative position between shaft and shell caused by thermal expansion or installation error, and can be used as free end support. Cylindrical Roller Bearings The inner ring or outer ring can be separated for easy installation and disassembly.
for the shaft and seat hole are high. After the bearing is installed, the relative deviation of the inner and outer ring axis shall be strictly controlled Cylindrical Roller Bearings to avoid contact stress concentration.
with 1:12 taper in inner hole has adjustable radial clearance and high radial stiffness, which is suitable for Cylindrical Roller Bearings machine tool spindle.
The higher the speed, the larger the contact angle, the higher the axial bearing capacity. Single row bearing can only bear axial load in one direction, which will cause additional axial force when bearing radial load. And can only limit the axial displacement of the shaft or housing in one direction. If it is installed in pairs, make the outer rings of a pair of bearings opposite, that is, the wide end face to the wide end face, and the narrow end face to the narrow end face.
additional axial force can be avoided, and the shaft or housing can be limited to the axial clearance in both directions. Cylindrical Roller Bearings There are more than 70 variant structures of angular contact ball bearings.
are 15 °, 25 ° and 40 °. The larger the contact angle is, the higher the axial bearing capacity is. High precision and high-speed bearings usually take 15 ° contact angle, which Cylindrical Roller Bearings will increase under the action of axial force.
is provided with a locking port, and the inner and outer rings cannot be separated. The outer ring is assembled with the inner ring, rolling element and cage assembly after heating and expansion. The number of balls installed is more than that of deep groove ball bearing. The rated load is large in the ball bearing, with strong rigidity and stable operation.
can be adjusted by the mutual displacement of the inner and outer rings. It is often used in pairs and preloaded to improve Cylindrical Roller Bearings the rigidity of the bearing.
A single bearing of this type can only bear the axial load in one direction. At the same time, other bearings need to be configured to offset their additional axial forces. When installed in pairs, their additional axial forces offset each other, and they can bear the axial load of two forces upward, and have strong axial limit capacity in two directions,
Generally, two sets of bearings are installed in pairs, with their outer ring wide end face opposite (back-to-back) or narrow end face opposite (face-to-face), in which the rigidity of the back-to-back installation bearing system. In order to facilitate installation in pairs or groups, some bearing factories supply bearings in pairs, three sets in groups and four sets in groups.
In this way, the processing consistency of the supplied bearings in the same batch is good, the load Cylindrical Roller Bearings is borne more evenly during use, and the additional axial forces offset each other more thoroughly.
This type of bearing can be divided into two types: separated type and non separable type. The separated type bearing is used when the installation conditions Cylindrical Roller Bearings are limited and the outer ring or inner ring is required to be removed from the whole set of bearings for separate installation.
Because the separated type angular contact ball bearing is widely used in magneto, it is also called magneto bearing. Cylindrical Roller Bearings In this type of bearing, the locking port is on the inner ring, which can be adapted to higher speed.
