Self-Aligning Ball B. FAG 2319 -K-M

The FAG 2319 -K-M double-row self-aligning ball bearing, with a tapered bore and brass cage, compensates for misalignment with a shaft diameter of 95 mm.

The FAG 2319 -K-M double-row self-aligning ball bearing is an open rolling bearing made from standard bearing steel (100Cr6) with main dimensions of 95 × 200 × 67 mm. The design features a common hollow spherical raceway in the outer ring, which allows shaft deflection and misalignment to be automatically compensated for during operation. Fitted with a brass cage and standard radial clearance, this bearing is suitable for demanding industrial applications. It covers an operating temperature range of –30 to +150 degrees Celsius and complies with tolerance class P0/PN or ABEC 1.

What functions does the 2319 -K-M self-aligning ball bearing perform in operation?

The 2319 -K-M self-aligning ball bearing is recommended for use where shafts flex elastically or where manufacturing-related misalignment occurs between housing seats. Thanks to its double-row design, the bearing absorbs radial forces and allows angular adjustment movements without causing impermissible edge loads on the rolling elements. The brass cage guides the rolling elements stably under dynamic loads. Typical applications include general mechanical engineering and bearing arrangements with longer support spans.

What are the advantages of the tapered bore in the 2319-K-M?

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This design allows for direct mounting on a tapered shaft seat or for mounting on cylindrical shafts using a clamping or withdrawal sleeve. The axial displacement allows the bearing clearance to be precisely adjusted during installation. As this is an open bearing without an integrated seal, the type of lubricant and external sealing must be selected to suit the operating conditions of the respective bearing location.
