NO 2. Description: Tapered Roller Bearing
Tapered 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 Categories
SFNB production metric, inch single, double, four-row tapered roller bearings - Types
Single row tapered roller bearings
Such 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 bearings
Such 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 bearings
Performance 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.
Four-row tapered roller bearings
SFNB provide long-life 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%.
