22311CAC/W33 Bearing 55x120x43mm

 Spherical roller bearing has two columns of roller, mainly bear radial load, but also can carry axial load in either direction. Have high radial load capacity, especially suitable for overloading or under vibration loading work, but can\'t afford to pure axial load. This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate the alignment error.

Has two columns symmetric spherical roller type, there\'s a share of the spherical outer ring raceway, the inner ring has two the tilt Angle of a race to the bearing axis, has a good heart performance, when the axial stress bending or install different heart bearings can still be used normally, so vary with different bearing size series, generally allowed by the self-aligning Angle from 1 to 2.5 degrees, the type of bearing load capacity is larger, besides can bear radial load bearing can withstand the axial load, two-way role has good shock resistance, typically spherical roller bearing is allowed to work speed is low.

Self-aligning roller bearing press roller cross section shape is divided into symmetric form spherical roller and asymmetric form spherical roller two kinds of different structure, asymmetric spherical roller bearings belong to the early products, primarily for the host service, a new design when the host is rarely choose symmetric spherical roller bearing, the internal structure after comprehensive improvement design and parameter optimization, compared with the early production of spherical roller bearings, able to bear a greater axial load, the bearing operating temperature is low, so it can adapt to the requirement of high speed, according to the inner ring with or without rim and retainers used different could be divided into two kinds of type C and CA, C type bearing inner ring is the feature of no guard and USES the steel plate stamping cage, the CA model, Ryan bearing characteristics of inner ring on both sides of the car system entities have a guard and use to maintain in order to improve the bearing lubrication, can provide the user with outer ring with a ring groove and oil hole of the three spherical roller bearing, expressed as a rear bearing code/W33, according to the requirement of the user can also supply with spherical roller bearing inner ring oil hole, in order to facilitate customer handling and replace bearings, also can provide inner hole bearing, spherical roller bearing with taper cone hole taper 1:12 for later nicknamed K said, in order to adapt to the requirement of special user could also provide inner hole taper bearings for 1:30, then buy code-named K30 inner hole of the tapered bearing lock nut will be available bearing directly on the conical journal, also can with tight sleeves or withdrawal will be installed on the cylindrical journal bearings. In order to ensure the bearing at high speed to prevent due to centrifugal effect between the raceway and roller produces harmful slip, the minimum radial load bearing should bear a certain size can press type estimation:

Fr = 0.02 C

Type in the

N Fr - minimum radial load

C - bearing the basic dynamic load rating of the N

Equivalent dynamic load

P = Fr + Y1Fa when Fa/Fr e

P = 0.67 Fr + Y2Fa when Fa/Fr e

Type in the

P - equivalent dynamic load N

Y1 Y2 - axial dynamic load coefficient

The equivalent static load

P0 = Fr + Y0Fa

Type in the

P0 - equivalent static load N

Y0 - axial static load factor
