NU2276-E-M1A

The FAG NU2276-E-M1A is a premium single-row cylindrical roller bearing engineered for demanding industrial applications. With main dimensions of 380 mm inner diameter, 680 mm outer diameter, and 175 mm width, this bearing is built to handle extremely heavy radial loads, boasting a substantial basic dynamic load rating (C_r) of 4,050,000 N and a static rating (C_0r) of 6,700,000 N. The 'E' suffix signifies an enhanced design with a larger roller set, maximizing its load-carrying capability without changing the boundary dimensions. Furthermore, the robust brass cage ('M1A' suffix) is outer ring-centered, providing excellent guidance for the rollers, which, combined with the bearing's open design, supports high-speed operation up to a limiting speed (n_G) of 1,420 1/min.

Designed in the 'NU' configuration, this bearing features two integral ribs on the outer ring and a smooth inner ring without ribs. This specific geometry makes the NU2276-E-M1A an ideal choice for use as a floating bearing (non-locating) in a shaft assembly. This floating function is crucial as it allows for the necessary axial displacement between the shaft and the housing in both directions, compensating for thermal expansion or minor mounting inaccuracies. Its separability simplifies the installation and dismounting process, a key advantage in heavy machinery maintenance across industries like gearboxes, large electric motors, pumps, and metal recycling equipment. Choosing the NU2276-E-M1A ensures high rigidity, enhanced operational reliability, and a long service life under tough operating conditions.
