Description
product introduction :Cylindrical roller and raceway are linear contact bearing s .large load capacity,mainly bear radial load .The friction between the rolling body and the rim of the ring is small, suitable for high -speed rotation .According to whether the ring has a guard ,it can be divided into NU,NJ,NUP,N,NF and oter single row cylindrical roller bearing ,and NNU,NN and other double row cylindrical roller bearings. The bearing is a sparable structure with inner and outer rings.
Cylindrical roller bearings with inner or outer rings without guards,whoes inner and outer rings can move relative to each other in the axial direction ,so they can be sued as free-end bearings .One side of the inner ring and the outer ring has a double guard, and the other side of the ring has a single guard cylindrical roller bearing, which can bear a certain drgree of axial load in one direction .Generally use steel plate stamping cage, or cooper alloy car solid cage. But some use polyamide forming cages.
Application field :Cylindrical roller bearings are suitable for large and medium sized motors ,rolling vehicles, machine tool spindles, internal combustion engines, generators, gas turbines, reduction boxes, rolling machines ,vibration screens and lifting and transportation machinery .
