Taper roller thrust bearings enable axially very compact bearing arrangements to be produced which can carry very heavy axial loads, Are insensitive to shock loads and are stiff ZWHZZ produces single direction taper roller thrust bearing and double direction taper roller thrust bearings. The screw- Down bearings constitute a special design of single direction taper roller thrust bearing and have a full complement of rollers. They are used for rolling mill screw- Down arrangements.
Cylindrical roller thrust bearings are suitable for arrangements that have to support heavy axial loads. Furthermore, They are relatibely insensitive to shock loads, Are very stiff and require little axial space. As standard they are available as single direction bearings and can only accomnodate axial loads acting in one direction. Cylindrical roller thrust bearings are simple in form and are produced in single row and double row designs. The bearings in the 811 and 812 series are mainly used where thrust ball bearings have insufficient load carrying capacity. The cylindrical surface of the rollers is slightly relieved towards the ends. The resulting contact profile virtually eliminates damaging edge stress. The bearings are of separable design: The individual components can be mounted separately.
