Sealed roll neck bearings havespecially designed sealing arrange- ments.This allows the bearings to endure harsh environments by helping to eliminate contamination from the bearing envelope, thereby extending bearing life. All Timken sealed roll neck bearings have spiral bore grooves with blended radii to eliminate roll neck damage.Types TQITS and TQITSE consist oftwo pairs of indirectly mounted bearings, two single and one double cone, four single cups and three cup spacers. Type TQITSE has an extension to the large bore cone adjacent to the roll body. This not only provides a hardened, concentric and smooth surface for radial lip seals, but also improves roll neck rigidity by eliminating afillet ring. This feature allows the centerline of the bearing to move closer to the roll body, and it also permits shorter and less costly rolls. The indirect mounting of both the TQITS and the TQITSE increases the overall effective spread of the bearing to deliver optimum stability and roll rigidity.

Type TQITS

Size range: 50.8 mm – 1,219.2 mm bore (2” – 48”) Some applications require a level ofprecision that cannot be achieved with astandard tapered roller bearing. Timken precision tapered roller bearings promote and maintain theoperating accuracy required of today’smachine tool industry and various related specialized markets. Precision class tapered roller bearings offer machine tool builders an economical design solution that exceeds most application needs for rotational accuracy and rigidity. Precision classes range from Class 3 (C)to Class 000 (AA).
