China Factory Supply Taper Roller Bearing * Product
FeaturesTapered roller bearings inside, the outer ring has a
tapered raceways, raceway fitted between the tapered roller. If
tapered surface extending eventually converge to a point on the
bearing axis. Tapered roller bearings are mainly used to bear
radial load mainly radial, axial joint load. Axial bearing capacity
by the contact angle, the greater the reach, the greater the axial
load capacity Tapered roller bearings for the separation of
bearings, with roller and cage inner ring inner components can be
installed separately from the outer ring This kind of bearing shell
limit the axis or axial displacement side allowed tilt axis
relative to shell hole. In the radial load, it will produce
additional axial force, therefore, generally in two support
bearings, the bearing outer ring and inner ring with the face
should be relatively installation.The main purpose of such
bearings: automotive front, rear, transmission, differential,
pinion shaft, spindle, construction machinery, large-scale
agricultural machinery, railway vehicles, gear reduction, the
rolling mill roll neck small deceleration devices.* Product
CategoriesZGXSY production metric, inch single, double,
four-row tapered roller bearings - TypesSingle row tapered roller
bearingsSuch bearings can only limit shaft or housing in one
direction of the axial displacement in one direction to bear the
axial load. In the radial load of action, the axial force generated
in the bearing must also be balanced. Two face to face or back to
back bearing should be used.Double row tapered roller bearingsSuch
tapered bearings in radial load at the same time can withstand
axial load. The axial clearance in the bearing within the shaft or
housing to limit axial movement of the two-way.Four-row tapered
roller bearingsPerformance of such bearings and double row tapered
roller bearing is basically the same, but more than double row
tapered roller bearings under radial load bigger, lower speed
limits, mainly for heavy machinery, such as rolling
machines.Multi-sealed double, four-row tapered roller bearingsZGXSY
provide long-life, multi-sealed double, four-row tapered
roller bearings. Personalize bearing the new design, fully sealed
bearing change traditional design method, using the new structure
type seal and dust seal combination, to improve the sealing effect,
improve sealing performance. Multi-sealed double, four-row tapered
roller bearings compared with open structure bearing, life
expectancy increased by 20% to 40%; lubricant consumption reduced
by 80%.Multi-sealed bearings with post-code XRS

with a general tolerance level, but also provides P6X, P6, P5, P4,
P2 tolerance class products, all consistent with GB307.1.ZGXSY inch
tapered roller bearings with Normal tolerances, according to need
and available CL2, CL3, CL0, CL00 level tolerance
products.* radial clearanceZGXSY single row tapered
roller bearings are mounted only after clearance and another in the
opposite direction to adjust the positioning of the bearing can
only be determined after.* cageTapered roller bearings
generally use pressed steel, box-type cage, but the size is larger,
also uses machined solid pillar cage.1. When the bearing outer
diameter D≤650mm, the use of steel stamping cage, the cage not sign
post code2. When the bearing outer diameter D> 650mm, use of
steel pillars entities cage after cage code does not post
signs* Allow angle error* equivalent dynamic
loadSingle row tapered roller bearings used in pairs (basic
dimensions can be different), in calculating the equivalent dynamic
bearing load, must be included in the additional axial force radial
loads. Single row tapered roller bearing additional axial force S,
it can be approximated by the following formula: S = Fr /
2Y* equivalent static loadSingle row tapered roller
bearingsDouble-row and four-row tapered roller bearingsEquivalent
static loadFr and Fa are by acting on the single row, double row
and four row total load on the bearings.NTN tapered roller bearing
