Product Details

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.
