Thrust bearings in a wide range of industrial applications , and are generally used in large-scale machinery and other places, such as machine tools , electric motors, gear , etc., thrust bearings can be divided into several types , here we look at the following few thrust bearing a brief description of its main thoroughfare .

Thrust tapered roller bearings
These bearings with circular -shaped roller ( big endian spherical ) , the roller from the raceway ring ( shaft washer, housing washer ) ribs accurate guide
Designed so that the shaft ring and seat ring raceway and the roller rolling surface apex of the conical surface bearing center line intersect at a point
One-way bearings can withstand axial load , two-way bearings can withstand axial load
Two-way bearing to the ring with the shaft , but due to a loose fit , so you must make in the ring with the sleeve axial positioning , etc.
Mainly used to maintain frame: cutting copper alloy cage
Main purpose : Unidirectional : crane hook, swivel oil rig
Bidirectional: rolling mill roll neck

Axial spherical roller bearings
Kind of spherical roller bearings arranged obliquely , appear before the seat ring raceway spherical , aligning performance , thus allowing a number of axis tilt
Axial load capacity is very large, the axial load can also bear certain radial load
Used when using oil lubrication
Mainly used to maintain frame: cutting copper alloy cage
Main purpose: hydroelectric power, vertical motors, marine propeller shafts , rolling mill rolling screw with a reducer , tower cranes, coal grinding machines , extruders, molding machines

Thrust Ball Bearings
By the band raceway washer-shaped raceway ring and ball and cage components
And the shaft with raceway ring called shaft washer, and the shell with seat ring raceway ring called . Two-way bearing shaft with the secret will be in the ring
One-way bearings can withstand axial load , two-way bearings can withstand axial load ( both of which can bear radial load )
Mainly used to maintain frame: steel stamping cage, copper alloy or phenolic resin cutting cage , synthetic resin molded cage
Main purpose: automobile steering pin, spindle

Thrust cylindrical roller bearings
By the washer-shaped raceway ring ( shaft washer, housing washer ) and cylindrical roller and cage components . Cylindrical roller crowning used , so the roller and the raceway surface of the pressure distribution between the
Can withstand axial load
Axial load capacity, axial rigidity is also strong
Mainly used to maintain frame: cutting copper alloy cage
Main purpose: oil rigs, iron steel, machinery manufacturing

Thrust needle roller bearings
Separated by a roller bearing ring and needle roller and cage components can be used with thin stamping raceway ring (W) or processing of thick cut raceway ring (WS) any combination
Non-separable bearings are precision stamping by a raceway ring and needle roller and cage components of the overall bearing
Can withstand axial load
Bearing such a small footprint, compact design conducive to mechanical
Mostly using only needle roller and cage assemblies , and the shaft and housing mounting surface to use as a raceway
Mainly used to maintain frame: steel stamping , forming synthetic resin cage
Main purpose : cars, plowing , machine tools and other transmission
