tapered roller thrust bearings

Screw-down bearings are mainly used in the screw-down of rolling mills. This type of bearings has no cage and full of tapered rollers, so that can carry high axial loads and have low limiting speed. In order to improve the performance, the underside of the shaft washer is concave spherical surface (type TTSV00) or convex spherical surface (type TTSX00), they cooperate with the spherical side face of housing screws which have the same radius of curvature and are through precise finish, and both of them are uniform contact, so ensuring uniform stress of bearings when housing screws have obliquity relative to axial of bearings.
The bores of housing washers are screwed. The inner bores of shaft washers are also screwed for large-size bearings .These screw threads are used to install the lifting eye bolts.
The lube with extreme pressure additive should be chosen to form the lubricant film under heavy loads.
The lube with extreme pressure addictive should be chosen to form the lubricant film under heavy loads. On the spherical surface of shaft washer, dry film lubricant should be coated being well lubricated and aligned easily.

Screw-down bearings permit the angular movement of the screw spindle with respect to the support. It is suitable for very high axial loads and it is equipped with very long rollers of large diameter.

The shaft washer surface is ground to convex spherical surface TTSX type (4397/00 type) or concave spherical surface TTSV type (4297/0 type) to suit screw down spindle on the rolling mill, contact averagely the end face shape of screw down spindle. The bearing make sure the load on it average when some misalignment arises out of the axis and axis and screw down spindle. We must not mount the roller mixedly because the rollers of the bearing can’t been exchanged, and should make the bearings full of or grease.
