Thrust-aligning roller bearings and Spherical Roller Bearing Similarly, the seat pavement roller bearings with the Center on the same axis as the center point of the sphere, such as a spherical roller bearing type, with automatic cardiac function , Coaxiality Shaft and the deflection is not sensitive.
And samples of other thrust bearing, this type of axial load bearing capacity is very large, axial load to bear in the bear while a number of radial load, but the radial load should not exceed 55% of the axial load.
P load as long as no more than P0 and 0.05C0, and ring rotation axis, the bearings allow listed in the table below aligning angle.

  1 ° ~ 1.5 °
1.5 ° ~ 2 °
2 ° ~ 3 °
 



The small ＆#118alue applied to a larger bearing, but also allows the load increases, aligning angle will be reduced.
When using the commonly used lubricating oil.

Such bearings are mainly used in hydro-electric power, vertical motor, a ship with the propeller shaft, tower cranes, extruders, and so on.

Mid-size range
ZWZ Thrust Spherical Roller Bearing the basic dimensions are listed in the table size,
Diameter size range: 60mm ~ 1120mm
Outside diameter size range: 130mm ~ 1460mm
High range of sizes: 39mm ~ 354 mm
 
● Tolerance
ZWZ provide P0, P6, P5-class products tolerance.
◇ Cage
Cage entities generally brass frame and frame stamping. Cage used brass entity, the post-Cage code does not sign, sign the rest of the post code.
◆ Minimum axial load

Thrust Spherical Roller Bearing work required minimum axial load,
Famin (check the following two large-calculated ＆#118alue)
Famin = C0a/2000

Famin = 1.8Fr +1.33 (C0a/2000) 2 ×

Where:
Famin: the required minimum axial load kN
n: Speed
C0a: basic rated static load kN
Fr: radial load kN
 
□ equivalent dynamic load
P = Fa +1.2 Fr
■ equivalent static load
P0 = Fa +2.7 Fr

Such bearings are mainly used in oil drilling, iron-steel machinery.
