Screw-down Bearings

We offer two types of screw down bearings – type TTSV and type TTSX. Both types consist of a full roller complement design without cages. Tapered roller thrust bearings of this type mostly used to carry extremely heavy axial loads and also permit angular movement of the screw spindle with respect to the support. But the limiting speed is low.
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 as screwed hole or oil hole when we install and lift the bearings.
