Cylindrical Roller Bearings FAG NJ324 -E-XL-TVP2

The NJ324 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager is a single-row support bearing with a polyamide cage, designed for shafts with a diameter of 120 mm under heavy radial loads.

The NJ324 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing with a cylindrical bore, designed for demanding applications in mechanical and plant engineering. With key dimensions of a 120 mm bore, 260 mm outside diameter and 55 mm width, this design can withstand high radial forces. The open bearing complies with the standard tolerance class P0/PN (ABEC 1) and has a standard radial clearance. Thanks to the removable inner ring, the bearing rings can be fitted separately with ease.

In which applications is the NJ324 -E-XL-TVP2 support bearing used?

This rolling bearing is primarily used where strong radial forces act on the shaft and single-sided axial guidance is required. As a support bearing, the NJ design absorbs axial forces from one direction whilst compensating for linear movement in the opposite direction. Typical applications include bearing arrangements subject to thermal shaft expansion. Thanks to its open design, the bearing can be flexibly connected to an external lubrication supply or a housing oil bath.

What features does the NJ design with a polyamide cage offer?

The version with a polyamide cage guides the cylindrical rollers quietly and with low friction within the bearing assembly. The permissible temperature range is from –30 to +120 degrees Celsius. The inner ring, which can be withdrawn from one side, facilitates assembly and ensures a precise fit within the housing. As the outer ring is manufactured without a lubrication groove or lubrication bore, the lubricant is supplied axially via the housing side. It should be noted that the axial force must always be directed towards the fixed edge of the inner ring.
