RKB thrust ball bearings are manufactured in single and double directions. They can carry only heavy axial loads.
The single direction bearings consist of shaft washer, housing washer and ball cage assembly.
Thrust ball bearings with sphered housing washer can be used with sphered seating housing to compensate the misalignment between the support surface and in the shaft.
The boundary dimensions of RKB thrust ball bearings in metric size conform to ISO 104/1979.
They are produced to normal tolerance class in accordance with ISO 199/1997.
RKB big size thrust ball bearings are normally fitted with machined brass cage (suffix M). Machined steel cage (suffix F) is available.
They are generally used to take over heavy pure axial loads, to carry shock loads and to be stiff into a little axial space.
Double direction cylindrical roller thrust bearings can be easily obtained.
In case of more rows, the rollers have various lengths and are alternatively mounted.
The boundary dimensions is conform to ISO 104/1979.
In order to guarantee a proper arrangement of the rolling parts for the satisfactory operation, they have always to be submitted to a given minimum load.
Both machined brass and steel cages are available as standard.
RKB production range also includes inch size cylindrical roller thrust bearings.
There are standard design variations of RKB inch series. Each design is based on a standard single acting with addition of special components: the AT aligning type; the crane hook thrust type; the DT double acting thrust bearing and the DAT aligning style combination of DT and AT types; the SDT simplified double acting thrust. |

Thrust ball bearings
Feature:
This type of bearings is separable and the contact angle is 90 degree.So the bearings can only carry axial load. While the bearings runing, the balls are extruded to the outside of raceway by centrifugal effect and easy to be scraped. So this typy of bearing can not be used under the high speeds condition.
The single direction bearings of them can only carry axial load in one direction, while the double can carry alternating axial load in either direction.
And the trust ball bearings with spherical outer ring have self-aligning functions.
In double-direction angular contact thrust ball bearings, the contact angle is 60 degree. they can take axial load forn double-directions and the unit load form axial and radial drection. Furthermore, the bearings have a capacity of axial space limiting,and also do a little to the radial space limiting.
CAGES:
Pressed steel and machined brass cages are commonly used.
APPLICATIONS:
The thrust ball bearings are used in lathe centers, automobile clutches, reducers and so on. |

APPLICATIONS:
Special applications with axial loads |
|
Torque Transmission's Thrust Bearing design incorporates the optimum combination of molded nylon retainer, with hardened grade steel balls and washers. The self-lubricating property of nylon, combined with the hardened steel, high-grade balls reduces friction and the micro finish thrust washers reduce noise and increase durability.
We manufacture high quality thrust bearings in a wide range of sizes - standard, metric and custom dimensions - to meet your specific application.
High Quality Construction:
- Retainers are injection molded 6/6 nylon held to a rigid design criteria assuring consistent quality
- Hardened steel balls are grade 100 tolerance (±.0001", ±.0025mm)
- The thrust washers are hardened finished to micro 10 |
