Cylindrical roller bearings are assemblies consisting of integral inner and outer rings, cylindrical rollers, and a cage. They are separable bearings, making installation and disassembly very convenient. Because of the linear contact between the inner and outer ring raceways and the rollers, edge stress is eliminated, allowing them to withstand large radial and impact loads. Cylindrical roller bearings have a low coefficient of friction, low operating resistance, and can be used at high limiting speeds.
Based on whether the rings have flanges, common types include:
Single-row cylindrical roller bearings: N, NU, NJ, NF, NUP
Single-row full complement cylindrical roller bearings: NCF, NJG
EISENBERG cylindrical roller bearings are mainly used in large and medium-sized electric motors, locomotives and rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, speed reduction devices, rolling mills, vibrating screens, construction machinery, large agricultural machinery, and loading and unloading machinery.
Common suffixes for cylindrical roller bearings:
N – Flanges on both sides of the inner ring, no flanges on the outer ring
NJ – Flanges on both sides of the outer ring, flange on one side of the inner ring
NU – Flanges on both sides of the outer ring, no flanges on the inner ring
NUP – Flanges on both sides of the outer ring, flange on one side of the inner ring, and a movable flange on the other side
NF – Flanges on both sides of the inner ring, flange on one side of the outer ring
M – Double-assembly machined brass cage, roller-centered
NCF – Two integral flanges on the inner ring, one integral flange on the outer ring
NJG – Comprising heavy-duty size 23 series, for heavy-load, low-speed applications. These bearings have two integral flanges on the outer ring and one integral flange on the inner ring.
CV – Modified internal design, full complement of rollers
VH – Full complement of rollers (without cage), self-locating rollers
V – Full complement of rollers (without cage)
