Thrust roller bearing


Size range:

90 mm to 1000 mm

(4.3307 in. to 33.4646 in.)

Design Attributes:

Spherically contoured rollers, arranged in a steep angular position, accommodate high thrust loads and support moderate radial loads.

Bearing geometry and manufacturing technology result in low friction of bearing.

Internal self-alignment of bearing elements during operation compensates for shaft deflections and housing distortions caused by shock or heavy loads.

The TSR’s inherent compensation for misalignment offers equipment designers the opportunity to use weldments for housing frames instead of complex castings, which reduces machining costs.

When castings are preferred, bore alignment is less critical if spherical thrust bearings are specified.

“E” styles utilize enhanced bearing geometry allowing for higher dynamic load ratings and improved lubrication characteristics.

Applications:

Blowout preventers

Classifiers

Extruders

Gearboxes

Metal mill work/back-up rolls

Pre-heater fans

Pumps

Screw conveyors



PRODUCT FEATURES

Unlike other thrust bearings in the sample, these bearings have a very high axial load capacity and can withstand several radial loads while being subjected to axial loads, but the radial loads must not exceed 55% of the axial load.

As long as the loads P and P0 do not exceed 0.05C0 and the shaft rotates, the bearings allow the centering angles listed in the table below.

Bearing Diameter Series Self-aligning Angle Bearing Diameter Series Self-aligning Angle 200 Series 1°~1.5°300 Series 1.5°~2°400 Series 2°~3° Small values are suitable for larger bearings, and are allowed when the load is increased. The centering angle will decrease.

Oil lubrication is generally used when in use.

Thrust tapered roller bearings can only bear one-way axial load and can limit the axial displacement of the bearing in one direction, so it can be used as one-way axial positioning. Compared with the thrust cylindrical roller bearing, the bearing capacity is large, the relative sliding is small, but the limit rotation speed is low.

Feature

In this type of bearing, the spherical roller is arranged obliquely. Since the raceway surface of the raceway is spherical and has a self-aligning property, the shaft can be allowed to have some inclination

The axial load capacity is very large, and it can withstand several radial loads while being subjected to axial load

Generally used for oil lubrication

Applications

Hydroelectric generators, vertical motors, propeller shafts for ships, reducers for rolling mill rolling screws, tower cranes, coal mills, extruders, forming machines
