Cylindrical Roller Bearings FAG N221 -E-M1

The FAG N221 -E-M1 cylindrical roller bearing, measuring 105 x 190 x 36 mm, offers high radial load-carrying capacity as a separable loose bearing.

The N221 -E-M1 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for demanding industrial applications. With a bore of 105 mm, an outside diameter of 190 mm and a width of 36 mm, this design can withstand considerable radial forces. The solid brass cage guides the cylindrical rollers precisely and is suitable for operating temperatures ranging from -30 to +150 degrees. The open bearing has standard radial clearance and a tolerance class of P0/PN or ABEC 1 for reliable use in mechanical engineering.

What is the N221 -E-M1 cylindrical roller bearing suitable for in mechanical engineering?

This single-row cylindrical roller bearing is primarily intended for bearing arrangements that must accommodate high radial forces. Typical applications include compact bearing arrangements with axial shaft displacement. As the outer ring is designed to be removable on both sides, the design functions purely as a non-locating bearing. It compensates for changes in shaft length caused by thermal expansion without any restriction within the bearing itself. The absence of a lubrication groove on the outer ring requires a targeted supply of lubricant via the housing design.

What are the advantages of the brass cage and the N-type non-locating bearing design?

In the N design, the inner ring has fixed flanges, whilst the outer ring remains flangeless and can be removed from both sides. This makes assembly considerably easier, as the inner and outer rings can be fitted separately. The built-in brass cage helps to ensure stable roller guidance, even under vibration. As this is an open bearing without an integrated seal, designers can tailor the lubricant and external sealing to the specific environmental conditions.
