Cylindrical Roller Bearings FAG N228 -E-M1

The N228 -E-M1 cylindrical roller bearing, measuring 140 × 250 × 42 mm, serves as a non-locating bearing designed to accommodate high radial loads.

The N228 -E-M1 cylindrical roller bearing is a single-row radial roller bearing from FAG Wälzlager with a bore diameter of 140 mm, an outer diameter of 250 mm and a width of 42 mm. This version features a standard radial clearance and tolerance class P0/PN (ABEC 1). As a pure thrust bearing, the N design accommodates thermal linear changes in the shaft directly via the axial displacement capacity of the bearing. The brass cage guides the cylindrical rollers precisely and is designed for an operating temperature range of –30 to +150 degrees Celsius.

In which applications does the N228 -E-M1 cylindrical roller bearing prove its worth?

This single-row cylindrical roller bearing is designed for industrial applications involving high radial loads. Typical applications include general mechanical engineering and heavy-duty gearbox designs where axial shaft expansion must be compensated for without constraint. The outer ring’s flangeless design allows the bearing to move freely in the axial direction. Design engineers use this design where radial load-carrying capacity and rigidity are required in continuous operation.

What are the distinctive features of the N design and the brass cage?

The N design features two fixed flanges on the inner ring, whilst the outer ring is flangeless. This allows the inner and outer rings to be fitted separately, which facilitates assembly in the case of tight fits. The brass cage (designator M1) offers high mechanical strength under vibrations and dynamic accelerations. As the outer ring is manufactured without a groove or lubrication bore and no seals are integrated, the lubricant is supplied via the surrounding housing.
