Thrust Needle Roller Bearings Thrust Needle Roller Bearings Thrust Needle Roller Bearings are a type of Needle Roller bearing with a cage.

The composition of bearing numbers is as follows: 1 and 2). The surface-hardened cage offers superior wear resistance and strength. Our integrated-type Bearings with raceway washer are designed for applications where a low profile is desired and can easily replace conventional Thrust washers. Different thicknesses of various types of raceway washers are available for these Bearings , which allow selection of the appropriate thickness suited to bearing mounting conditions (see Fig. 3). An integrated (unitized) bearing , which consists of a cage, rollers, and raceway, is also available (see Fig.)

Outside diameter (mm). Type Code Bore diameter (mm) Type Code Unique number For inch Bearings , each dimension is expressed with whole numbers in units of 1/16 of an inch. Integrated Bearings have their own unique bearing number configuration. Fig. 1 Fig. 2. 3. Accuracy Standards The metric FNTA type conforms to ISO standards. The fitting tolerance of the inner dimension of the cage is class E11, and the outside diameter is class c12 (see Table 3). The inch NTA type and dimension tolerance for Thrust raceways of both systems of measurement are provided in the dimension table. Roller precision is equivalent to grade 3 of ISO 3096.
