Spherical Roller Bearing

Spherical roller bearings with two rows of rollers, the main radial load, but also can withstand any direction of the axial load. Has a high radial load capacity, especially for heavy duty or vibration load, but can not afford pure axial load. This type of bearing outer ring raceway is spherical, so the aligning performance is good, to compensate for coaxial error.

There are two symmetrical spherical roller, the outer ring has a common spherical roller, the inner ring with two inclined axis of the bearing
Angle of the raceway, with good self-aligning performance, bending or when the shaft is not installed when the heart is not the heart of normal use, self-aligning with the bearing size series vary, the general allowed angle of 1 ~ 2.5 degrees , The bearing capacity of the type of larger, in addition to radial load can bear outside the bearing can withstand the role of the axial load of two-way, with good impact resistance, in general Spherical roller bearings allow the working speed low.
Spherical roller bearings according to the roller cross-sectional shape is divided into symmetrical spherical roller and asymmetric spherical roller two different structures, asymmetric spherical roller bearing is an early product, mainly for the host maintenance services, the new design of the host It is rarely used symmetric spherical roller bearings, the internal structure of a comprehensive improvement of design and parameter optimization, and early production of spherical roller bearings compared to be able to withstand greater axial load, the bearing operating temperature Low, it can adapt to the requirements of higher speed, according to whether the inner ring and the use of the cage can be divided into C-and CA-type two, C-type bearing is characterized by no inner wall and the use of steel Stamping cage, CA-type characteristics of Trane bearing both sides of the inner ring and the use of the car body retaining cage. In order to improve the bearing lubrication, can be provided to the user with the outer ring ring groove and three oil hole of the spherical roller bearings to bearing the post-code / W33 said. According to the users requirements can also be supplied with the inner ring of the oil hole of the self-aligning roller bearings, in order to facilitate customer handling and replacement of bearings, but also provide bore with taper of the self-aligning roller bearings, cone taper 1:12 , To post-code for the K said that in order to meet the requirements of special users can also provide the bore taper 1:30 of the bearings, the post-code-named K30. Bearings with tapered bore The bearing can be mounted directly on the tapered journal with a locknut or the bearing can be mounted on a cylindrical journal with an adapter or withdrawal sleeve. In order to ensure that the bearings in high-speed operation to prevent the centrifugal effect in the raceway and roller between the harmful slip, the bearing should be subject to a certain minimum radial load, the size can be estimated according to the following formula:
Fr = 0.02C
Fr - the minimum radial load N
Basic dynamic load rating of bearings
Equivalent dynamic load
P = Fr + Y1Fa when Fa / Fr e
P = 0.67Fr + Y2Fa when Fa / Fr e
P-equivalent dynamic load N
Y1 Y2 - axial dynamic load factor
Equivalent Static Load
P0 = Fr + Y0Fa
P0 - Equivalent static load N
Y0 - axial static load factor
