Cylindrical Roller Bearings FAG NU234 -E-M1

The FAG NU234 -E-M1 cylindrical roller bearing, a single-row idler bearing measuring 170 × 310 × 52 mm with a brass cage, offers high radial load-carrying capacity under demanding operating conditions.

The FAG NU234 -E-M1 cylindrical roller bearing is a single-row radial roller bearing designed for heavy industrial loads. With a bore of 170 mm, an outside diameter of 310 mm and a width of 52 mm, the design can withstand high radial forces. Maintenance engineers and designers use the open design with standard radial clearance for bearing arrangements with external lubrication. Manufacture to tolerance class P0/PN (ABEC 1) contributes to dimensionally stable guidance in mechanical engineering.

What is the NU234 -E-M1 cylindrical roller bearing suitable for?

This roller bearing is primarily used as a support bearing in heavy-duty industrial drives, gearboxes and industrial plant. Thanks to the line contact between the rollers and the raceway, the bearing can withstand considerable radial loads. As the inner ring can be removed from both ends, the NU design compensates for thermal linear changes in the shaft relative to the housing without any forced alignment within the bearing. Furthermore, the ability to dismantle the bearing facilitates the separate assembly of both rings in large machines.

What is the function of the brass cage in this NU design?

The solid brass cage (designation M1) guides the cylindrical rollers precisely and withstands high accelerations and vibrations during operation. It performs well under demanding lubrication conditions and at elevated operating temperatures, as the bearing is designed for a temperature range of -30 to +150 degrees. The outer ring is designed without a lubrication groove or bore. Ensure external seals are fitted to keep contaminants out of the bearing interior.
