Double row cylindrical roller bearing, full complement catalogue
Brass Holder Single Row Cylindrical Roller Bearing
254941QU(NNAK6/206.375Q4/W33XYA2) for pump F-1600
Description:
the cylindrical rollers are in linear contact with the raceways.
They have a high radial load capacity and are suitable for high
speeds.In which either the inner or outer rings has two ribs and
the other ring has one, are capable of taking some axial load in
one direction Double-row cylindrical roller bearings have high
radial rigidity and are used primarily for precision machine tools.
Some cylindrical roller bearings have no ribs on either the inner
or outer ring, so the rings can move axially relative to each
other. These can be used as free-end bearings.
NN Series
NN Series - Bearings of NN design are double row cylindrical roller
bearing and have three fixed ribs on the inner ring that retain the
rollers and cage and one smooth outer ring. This design allows an
axial displacement in certain limits, of the shaft in relation to
the housing. Therefore, N Series rolling bearings are used in
non-locating bearing units. Also, the NN Series bearings have no
virtually thrust capacity.
