China Thrust Roller Bearing Wholesales

Thrust roller bearings are used to bear the combined axial and radial load with the main axial load, but the radial load shall not exceed 55% of the axial load. The design of this type of bearing with the main axial load coincides with that The main bearings are complementary and use the same type of roller design.

Basic design bearings

1. Spherical roller bearings-Thrust spherical roller bearings

Spherical roller thrust bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers

Depending on their series and size, EASIER spherical roller thrust bearings are manufactured to two basic designs. Their cage forms a non-separable unit with the shaft washer and rollers.

Bearings with no designation suffix

· example: 29272

· are fitted with a machined brass prong-type cage as standard 

E design bearings

· are identified by the designation suffix E

· have larger rollers and an optimized internal design for increased load carrying capacity

· are fitted with one of the following cages, depending on bearing size:

o size ≤ 68 → stamped steel window-type cage 

o size ≥ 72 → machined metal prong-type cage

2. Cylindrical roller bearings, thrust cylindrical roller bearings

Cylindrical roller thrust bearings are designed to accommodate heavy axial loads and impact loads. They must not be subjected to any radial load. The bearings are very stiff and require little axial space.

EASIER supplies cylindrical roller thrust bearings in different series:

--  811 and 812 series bearings with one row of rollers 

They are mainly used in applications where thrust ball bearings do not have sufficient load carrying capacity.

-- 893 and 894 series bearings with two rows of rollers

3. Tapered roller bearing, thrust tapered roller bearing

Tapered roller thrust bearings are designed to accommodate heavy axial loads and peak loads. The bearings are very stiff and require little axial space.

 tapered roller thrust bearings in the following basic and application-specific designs:

· single direction tapered roller thrust bearings

· double direction tapered roller thrust bearings

· screw-down bearings

4. Thrust Crossed Roller Bearing

EASIER designs crossed roller bearings (TXRs) to offer the highest levels of rotation accuracy and rigidity while conserving space and saving material costs. Able to withstand high overturning moments, TXR bearings are ideal for the table bearing of machine tools, including vertical boring and grinding machines. They also are uniquely suited to many pivot and pedestal applications where space is limited or the lowest possible center of gravity of a rotating mass is required.
