Cylindrical roller bearings

Bearings where cylindrical rollers are in line contact with raceways. Large load capacity, mainly bearings radial load .The rolling body has little friction with the guard edge of the collar, which is suitable for high-speed rotation

NU,NJ,NUP,N and NF single-row bearings, and NNU and NN double-row bearings are divided according to whether or not the collar is flanged .The bearings inner ring, outer ring detachable structure .Cylindrical roller bearings with inner ring or outer ring without guard, the inner ring and outer ring can be moved relatively as axial direction, so it can be used as free end bearings
A cylindrical roller bearings with two guard edges on one side of the inner ring or outer ring and a single guard edge on the other side of the ring can bear a certain degree of axial load in one direction. Double row cylindrical roller bearings, high rigidity to radial load is mainly used for machine spindle, generally used steel plate stamping cage, or copper alloy car cage. But some used polyamide forming cage
According to the cylindrical roller edge of the presence or absence, he is divided into the following situations
