Spindle bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed versions.
Spindle bearings have restricted tolerances. They are particularly suitable for bearing arrangements with very high requirements for guidance accuracy and speed capacity. They have proved highly suitable for the bearing arrangements of spindles in machine tools.

Thin section ball bearings applied in robot wrists; high stiffness and accuracy. Available in 4-point contact version as well as in angular contact configuration

RBC thin section ball bearings are engineered to solve a variety of
design problems that cannot be solved with conventional ball bearings.
A bearing is considered a thin section when the bore diameter is greater
than four times the radial cross section. Within any thin section bearing
series, the cross section remains constant as the bore diameter changes.
Typically the cross section is twice the ball diameter, and nominal
dimensions are given in inches.
RBC thin section ball bearings are most often found where space limitations,combined loading, and weight restrictions pose unique design
requirements.

Bearings of this type consist of the washers with raceways and an assembly of ball and cage. The washer that contacts the shaft is called the shaft washer, and the one attached to the housing is called the housing washer. Thrust ball bearings are designed to accommodate thrust loads at moderate speeds, for practical purposes their radial load capacity is nil. The mounting is relatively simple as the washers and the ball and cage assembly can be mounted separately as Thrust ball bearings are separable.
Bearings with a sphered housing washer can be used together with a sphered seating washer to compensate for misalignment between the support surface in the housing and the shaft as it’s important to keep the thrust bearings square with the shaft. However, the ability of the self-aligning seat to follow shaft wobble or misalignments is still quite limited.
Double direction thrust ball bearings characteristics are identical to those of the one-directional bearing, except it can accommodate axial loads acting in both directions and can thus serve to axially locate a shaft in both directions. To prevent adverse influence of centrifugal forces and gyration moments the single and double direction thrust ball bearings must be constantly subjected to a specific minimum load.

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.
RKB cylindrical roller thrust bearings are generally used to take over heavy pure axial loads, to carry shock loads and to be stiff into a little axial space with simple design.
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.

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

Thrust ball bearings consist of a shaft washer,a housing washer and a ball and cage thrust assembly.Th bearings are separable so that mountingg is simple as the washers and the ball and cage assemble can be mounted separately.Thrust ball bearings ,as their name suggests,can accommodate axial loads in one direction and thus locate a shaft axially in one direction.They must not be subjected to any radial load.

races: unless indicated as being polypropylene or polyethylene, all races are acetal.
balls: all balls are carbon steel. Other ball grades may be available upon request.

Thrust ball bearings are divided into single and double direction types. The former is able to accommodate axial load in one direction, while the latter is able to accommodate it in both directions. Neither is suitable for applications that involve radial load or high-speed rotation.
Bearings whose housing washer back face is spherical (with a spherical back face or aligning seat washer) are designed with a self-aligning capability and can accommodate the effects of inaccurate mounting.

Thrust ball bearings are separable axial bearings:
- Available in single direction and double direction designs
- Suitable for relatively high axial loads
- Low to medium speed ratings
- Standards: DIN 616, DIN 711, DIN 715
- Series: 51100, 51200, 51300, 51400
- Application examples: vertical shafts, etc.

Thrust ball bearings can handle axial loads only. Bearing rings mounted on the shaft are called shaft washers, and those mounted in the bearing housing are called housing washers. Both washers contain grooves for the balls. Thrust Ball bearings are of two types: single type which can support axial loads in only on direction and double type that can support bi-directional loads.
The central washer of double type thrust ball bearing is located in an axial direction by a shaft shoulder and sleeve. Thrust Ball bearings are not suitable for high-speed rotation since lubricant is expelled by centrifugal force. When used on a horizontal shaft, a minimum axial load must be applied. Pressed steel plate, polyamide resin, machined high-strength brass or mild steel are used for cages. Care must be taken in handling to prevent damage to the separable rings and ball assembly.
