FAG N220E bearings are cylindrical roller bearings?
Example: 6207NR. Four point contact ball bearing with two retaining slots on the outer ring of the N2-. Example: QJ315N2. S- outer ring with oil groove and three oil holes bearing. Example: 23040 is. The outer diameter of the bearing D is greater than or equal to 320 mm spherical roller bearings are not marked S. X- appearance size conforms to international standards. Example: 32036X. Technical specifications for Z..- special structures. From Z11 down in turn. Example: Z15- stainless steel bearings (W-N01.3541). ZZ- roller bearing with two guide outer ring retaining ring 3, sealing and dustproof RSR- bearing with sealing ring at one side. Example: 6207RSR. ZR- bearing with dust-proof cover. Example: 6207ZR. 2ZR- bearing with sealing cover on both sides. Example: 62072ZR. ZRN- bearing with dust cover, and the other side of the outer ring with a stop groove. Example: 6207ZRN. 2ZRN- bearing with dustproof cover on both sides, with stop grooves on outer ring. Example: 62072ZRN 4, FAG bearing cage and its material (1) solid cage. After the A or B is placed on the holder code, the A indicates that the cage is guided by the outer ring, and the B indicates that the cage is guided by the inner ring. F- steel solid cage, roller guide. FA- steel solid cage, outer ring guide. FAS- steel solid cage, outer ring leading, with lubrication groove. FB- steel solid cage, inner race guide.
MPA solid brass cage FAG bearing outer ring guide type suffix means 1, the internal structure of A, B, C, D, E change the internal structure of 1 cases: angular contact ball bearings 7205C, 7205E, 7205B, C-15 of the contact angle, contact angle of E-25 degrees, B-40 degrees of contact angle. Example 2: cylindrical roller, spherical roller and thrust roller bearings N309E, 21309E, 29412E- type design to strengthen, improve the bearing load capacity. Full complement cylindrical roller bearing VH- roller self-locking (standard bearing roller round diameter different from the same model). Example: NJ2312VH 2 and FAG bearing shape, size and external structure DA- separable double row angular contact ball bearing with double inner ring. Example: 3306DA, DZ- cylindrical roller bearings with outer diameter. Example: ST017DZ K- taper bore bearing, taper, 1:12. Example: 2308K. K30- tapered bore bearing, taper, 1:30. Example: 24040K30. 2LS- double inner ring, double row cylindrical roller bearing with double dust cover. Example: NNF5026C.2LS.V- internal structure change, double inner ring, double side dust-proof cover, full roller double row cylindrical roller bearing. Bearings on the outer ring of the N- with stops. Example: 6207N. NR- bearing with stop and stop rings on outer ring.
