HERO BEARING CO., LIMITED Spherical roller bearings SPHERICAL ROLLER BEARINGS NSK have two rows of rollers, which are mainly subjected to radial loads and can also withstand axial loads in either direction. SPHERICAL ROLLER BEARINGS NSK High radial load capacity, especially suitable for heavy load or vibration load, but Bearing 23126CE4 can not bear pure axial load. The SPHERICAL ROLLER BEARINGS NSK raceway of this type of bearing is spherical, so its centering performance is good and it can compensate for coaxiality error.
HERO BEARING CO., LIMITED There are two symmetrical spherical rollers, a common spherical raceway in the outer ring, and two inner rings inclined to the axis of the bearing.
Angle raceway, SPHERICAL ROLLER BEARINGS NSK with good centering performance, the bearing can still be used normally when the shaft is bent or installed with different bearing, Bearing 23126CE4 and the aligning property varies with the bearing size series. Generally, the allowed centering angle is 1~2.5 degrees. This type of bearing SPHERICAL ROLLER BEARINGS NSK has a larger load capacity. Bearing 23126CE4 In addition to the radial load, the bearing can also withstand the axial load in both directions, and has better impact resistance. In general, the working speed of the spherical roller bearing allows low.
Spherical roller bearings are divided into symmetrical spherical roller and asymmetrical spherical roller according to the cross-section of the roller.SPHERICAL ROLLER BEARINGS NSK The asymmetrical spherical roller bearing is an early product, mainly for the maintenance of the host, the new design of the host At the same time, symmetric spherical roller bearings are rarely used. The internal structure has undergone comprehensive improvement in design and parameter optimization. Compared with spherical roller bearings produced earlier, HERO BEARING CO., LIMITED it can withstand greater axial loads. The operating temperature of such bearings Lower, SPHERICAL ROLLER BEARINGS NSK can adapt to higher speed requirements, according to whether there are ribs in the inner ring and the use of different cage can be divided into two types of C and CA, C-type bearings are characterized by the inner ring without ribs and the use of steel plate Punching cages, CA type Trion bearings Bearing 23126CE4 are characterized by a rib on both sides of the inner ring and a solid body cage. In order to improve the lubrication of the bearing, the user can provide a spherical roller bearing with an annular oil groove and three oil holes in the outer ring, Bearing 23126CE4 is indicated by the bearing post code/W33. According to the user's requirements, spherical roller bearings with inner ring oil holes can also be supplied. In order to facilitate the loading and unloading of bearings by customers, bearings with self-aligning spherical roller bearings are also available. The tapered taper is 1:12. , The following code SPHERICAL ROLLER BEARINGS NSK for the K said, in order to meet the requirements of special users can also provide a 1:30 taper bore bearing, followed by the code K30. Taper bearings Bearing 23126CE4 with inner bore can be mounted directly on the conical journal by means of lock nuts, or the bearings can be mounted on cylindrical journals by means of adapter sleeves or withdrawal sleeves. In order to ensure that the bearing SPHERICAL ROLLER BEARINGS NSK is prevented from generating harmful slippage between the raceway and the roller due to centrifugal action during high-speed operation, the bearing should withstand a certain minimum radial load, and the size can be estimated as follows:
Fr = 0.02C
In the formula:
Fr -- Minimum radial load N
C—Bearing basic dynamic load rating N
Equivalent dynamic load
P=Fr+Y1Fa when Fa/Fr e
P=0.67Fr+Y2Fa When Fa/Fr e
In the formula:
P-equivalent dynamic load N
Y1 Y2—Axial dynamic load factor
Equivalent static load
In the formula:
P0—equivalent static load N
Y0—Axial static load coefficient
