The INA CRB-XL series Y-bearing (insert) is a single-row insert bearing with a spherical outer ring and a shaft locking system, designed to be mounted in split or flanged housings. It is used in equipment where the shaft must be supported and rotate with simple alignment, such as conveyor belts, fans, mixers and agricultural machinery. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, and advises you on choosing the correct part number for your application.

The CRB-XL series designation reads in blocks: CRB identifies the INA insert bearing family; the first number after the slash indicates the shaft diameter in millimeters, and the second, the main outer ring dimension. For example, CRB20/76-XL corresponds to a 20 mm shaft with a 76 mm outside diameter; CRB25/83-XL, to a 25 mm shaft with an 83 mm outside diameter. The -XL suffix indicates the manufacturer's current standard design. With those two data points you can locate the part in the catalog.

These insert bearings are mounted in split, pillow block or flanged housings, and are common in belt conveyors, bucket elevators, mixers, dryers, fans and equipment for the food, chemical and agricultural industries. In Argentina you will find them in processing plants, mills, animal feed plants and material handling systems. Their spherical outer ring allows a certain initial alignment, which simplifies mounting on welded structures.

To select the correct insert, take into account the shaft diameter, the locking type (set screws, eccentric or taper), the sealing required for the environment (dust, humidity, washdowns) and the expected radial and axial load. Mounting requires thoroughly cleaning the shaft, verifying that the tolerance is suitable and tightening the locking without forcing it. Factory lubrication can be supplemented according to the operating conditions. Careful alignment of the housing extends bearing life.

Y-bearings are available under different brands and designations, and each manufacturer has its own nomenclature. Interchangeability between brands is not automatic: shaft diameter, outer ring dimensions, locking type and sealing must be compared. In the INA CRB-XL series, the complete part number includes the shaft diameter and the outside dimension, which makes comparison with other references easier. If you have the original part number, we can help you find the equivalent.
