CYLINDRICAL ROLLER THRUST BEARINGS NSK is a particular type of roller bearing. Like other roller bearings, they permit rotation between parts, but they are designed to support a high axial load while doing this (parallel to the shaft). Higher speed applications require oil lubrication. Generally, they are composed of two washers (raceways) and the cylindrical roller elements which are typically caged. As opposed to roller thrust bearings, ball thrust bearings can generally operate at higher speeds but at lower loads.
CYLINDRICAL ROLLER THRUST BEARINGS NSK consist of two hardened and precision ground plates, a top and bottom, a milled brass cage, precision ground rollers and a cage band used to retain the rollers. The inside and outside diameters of the thrust plates are precision ground for proper mounting. The TP roller thrust bearings are available in a metric ISO series and an inch series, both series being industry interchangeable. The ATP self-aligning roller thrust is available in an inch series only. This spherically ground bottom plate of the ATP bearing sits against an alignment plate to accommodate initial misalignment but is not recommended for dynamics misalignment. Applications include extruders, screw presses, rock crushers, coal pulverizing, lathe tail stocks and oilfield equipment.
