N 228M Single Row Cylindrical Roller Bearing 140x250x42 Mm

N 228M Single Row Cylindrical Roller Bearing 140x250x42 mm

Cylindrical Roller Bearing, N 228M, 140x250x42 mm, Brass Cage, Single Row, No Seal, Outer Ring-Both Side Separable; No Snap Ring, Relubricatable, C3.

The N 228M is a single-row cylinder bearing with N design. The inner ring has two rigid ribs, while the outer ring has none. As a result, N bearings are only capable of supporting radial forces. This bearing type is commonly used as a floating bearing. Floating bearings allow axial displacement of the shaft relative to the housing in both directions. This is necessary in applications where the shaft material shrinks or expands due to temperature changes (thermal expansion).
