NTN Cylindrical Roller Bearing NN3008 nn Models
NN3008 Cylindrical roller bearing Single row cylindrical roller bearings depending on the ring wall structure is divided into N-type, NU type, NJ-type, NF-type NN-type: no outer wall, inner pairs of ribs; NU type: outer pairs block side, the inner ring without ribs; N-type and NU type bearings allow the shaft for bi-directional axial movement relative to the housing within a certain range, suitable for non-locating bearing. NJ and NF type bearings can withstand an indefinite degree of individual axial load, allows the shaft in one direction, the axial displacement of the NUP bearing can be used for bi-directional positioning bearings. Based on the use of different occasions, NU NJ-but also with HJ thrust collar combination
NN3008 Bearing Details (1)Shield / closure: Open bearing roller(2)Tolerance code: ABEC-1, ABEC-3, ABEC-5, ABEC-7 (3)Vibration level: V4, V3, V2, V1 (4)Radial play: C0, C2, C3, C4 (5)Material: stainless steel (6)Retainer: PTFE, nylon, PEEK or (stainless)steel
(7)High precision and high speed bearing general use 15degree contact angle
Cylindrical Roller Bearing Main use:Large and medium motor, Locomotive, Spindle, Engine, Dynamo, Gas turbine, Gear box, Rolling mill, Shaker and Hoisting and conveying machinery etc.Can be withstand radial load and axial load.Can be work at higher speed.The bigger contact angle,the higher axial load capacity.. Under the action of axial force, the contact angle will increase.Single row angular contact ball bearing can withstand axial load in one direction, Withstanding radial load will cause additional axial force.And can only limit shaft or housing axial movement in one direction.If paired double installation, To make a pair of bearing outer ring relative face to face,that is wide face to wide face,narrow face to narrow face.This can avoid additional axial force, but also in both of directions to make shaft or housing limited in axial clearance range.
