Features
Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings and cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling.
The cylindrical roller bearings have high rigidity, high radial load carrying capacity and, due to the cage, are suitable for higher speeds compared to full complement designs. Bearings with the suffix E have a higher capacity roller set and are thus designed for very high load carrying capacity.
Locating bearings
Cylindrical roller bearings NUP and NJ with HJ are locating bearings. Locating bearings can support not only high radial forces but also axial forces in both directions and can therefore guide shafts axially in both directions.
Bearings with rib washer
Type NUP has two ribs on the outer ring and one rigid rib on the inner ring. A loose rib washer is fitted on the opposite side.
L-section rings
L-section rings are advantageous where, under high loads, the seating surface of the inner ring in NUP bearings with a loose rib washer is too small to provide a sufficiently high bearing seat. In some applications, they make it easier to fit and dismantle the bearings.
Operating temperature
ingle row cylindrical roller bearings with cage can be used at operating temperatures from –30 °C to +150 °C. For continuous operating temperatures above +120 °C. Bearings with a plastic cage (suffix TVP2) are suitable up to +120 °C; the operating life is heavily dependent on the lubricant used.
