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
