Axial cylindrical roller bearings
Axial cylindrical roller bearings comprise axial cylindrical roller and cage assemblies and shaft and housing locating washers.
The bearings have particularly small axial section height, have high load carrying capacity and high rigidity and can support axial forces in one direction.
Axial cylindrical roller and cage assemblies
Axial cylindrical roller and cage assemblies comprise axial cages with one or two rows of cylindrical rollers. The cage assemblies have particularly small axial section height, high load carrying capacity and high rigidity. They can support axial force from one direction and act as non-locating bearings in a radial direction. Axial cage assemblies are combined with housing or shaft locating washers or are integrated directly in the adjacent construction. If they are used without

Axial spherical roller bearings are single row, self-aligning roller bearings. They comprise solid shaft and housing washers and asymmetrical barrel rollers with cages. The cage holds the roller and cage assembly together with the shaft locating washer. The bearings can be dismantled. The parts of the bearings can be fitted separately.
Axial spherical roller bearings can support very high axial loads and permit relatively high speeds. Since the raceways are at an angle to the bearing axis, the bearings can also support radial loads. |

Cylindrical roller thrust bearings are separable axial bearings:
- Available in single direction as standard, double direction upon request
- Suitable for high axial loads
- Insensitive to shock loads
- Low to medium speed ratings
- Standards: DIN 616, DIN 722
- Series: 81100, 81200
- Application examples: injection moulding machines, presses, etc. |

In RKB spherical roller thrust bearings the load is transmitted from one raceway to the other under an angle of about 50° related to the bearing axis.
They can take over heavy axial loads and simultaneously they can accommodate radial loads with values of up to 55% of the axial load magnitude.
An important feature of spherical roller thrust bearings is their self-aligning capability, thanks to the design of the housing and shaft washer raceways with a large number of asymmetrical rollers and the proper conformity with the paths.
RKB spherical thrust bearings have a machined brass cage guided by a sleeve clamped in the shaft washer bore (suffix EM). The shaft washer and the cage with rollers form a non-separable unit.
The overall dimensions of the spherical roller thrust bearings are in accordance with ISO 104/1979, so that they are interchangeable with different designs, even the earlier ones (suffix B).
Where the cage guiding sleeve also serves as a spacer sleeve, the spacer sleeve needed between the shaft washer and the shaft shoulder has to be checked and, if necessary, remachined when substituted with different bearing designs.
These RKB bearings as standard are manufactured to normal tolerance class as specified in ISO 199/1997. However the tolerance for the total height is tighter than that specified by ISO. |

Tyson Tapered Thrust Bearings are used in applications where heavy loads are present. Tyson Tapered Thrust Bearings offer:
Sealed versions where lubrication is problematic or space constraints do not offer the luxury of a shaft seal
Unsealed versions available
Case carburized bearing quality steel
Size ranges from 1 inch to 3 inches bore diameters |

RKB taper roller thrust bearings have separable parts: shaft washer, housing washer and rolling element assembly.
RKB program includes the single direction type, the double direction type and the screw-down special type.
RKB bearings are manufactured in two constructive versions.
The rollers are radially guided by the rib of one washer (suffix ZB).
These bearings can also be produced in the version without the cage (suffix V).
The most common series are T, TK and 351 type.
Bearings made of case hardened carburizing alloy steels can be produced.
RKB bearings are used in the rolling mill applications associated.
RKB produces this type of bearing in two constructive versions, either with central plane shaft washer and taper raceways in both housing washers or with both plane housing washers and taper raceways in the central shaft washer.
A special sleeve is arranged, so no special adjustment of the bearing is required.
As the double direction taper roller bearings are usually mounted with loose fit on the roll neck, the shaft washer is normally provided with one or two locating slots that, engaged with key-way or similar devices, prevent the shaft washer from rotating on the seating.
The most common series are 350, 351, 353 and TTK type.
RKB screw-down bearings are a special design of the single direction taper roller thrust bearings used for rolling mill arrangements.
They are generally produced with case hardened carburizing alloy steels and with full complement of long rollers of large diameter.
The dimensions of taper roller thrust bearings are not standardized.
The main boundary dimensions are produced according to ISO 199/1979 |

Axial needle roller bearings
Axial needle roller bearings are units comprising axial needle roller and cage assemblies and axial bearing washers with a centring spigot. They can be combined with drawn cup needle roller bearings and needle roller bearings. The axial running surface for the needle roller and cage assembly must be hardened and ground.
Axial needle roller and cage assemblies
Axial needle roller and cage assemblies comprise plastic or metal axial cages with integrated needle rollers and have a very small axial section height. They can support high axial forces in one direction. Radial loads must be supported by separate means. Axial needle roller and cage assemblies require hardened and ground axial running surfaces for use as raceways.
