Cylindrical Roller Bearings FAG NJ324 -E-XL-TVP2-C3

The FAG NJ324 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 120 x 260 x 55 mm, offers high radial load-carrying capacity and single-sided axial guidance.

The NJ324 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing manufactured by FAG for heavy mechanical loads. In the NJ design, the bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. This makes it suitable as a support bearing that absorbs radial forces and limits axial displacement of the shaft in one direction. The inner ring can be removed from one side, which facilitates the assembly of the separate bearing rings.

What is the NJ324 -E-XL-TVP2-C3 design suitable for in machinery?

This bearing is primarily used in applications that require the absorption of high radial forces whilst accommodating thermal linear expansion of the supported shaft. The integrated polyamide cage (TVP2) guides the cylindrical rollers quietly and is characterised by its low weight. As this is an open bearing, lubrication is provided by the surrounding structure.

What are the distinctive features of the C3 bearing clearance and the polyamide cage?

The design with a slightly increased radial clearance (C3) compensates for operational heating or tight fits without the rolling elements becoming jammed. The permissible temperature range is between –30 and +120 degrees Celsius and corresponds to the thermal stability of the polyamide cage. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied from the side. Manufacture to tolerance class P0 or standard tolerance ensures installation in accordance with standards in standardised bearing seats.
