Bearing designations / bearing part numbers Guide

  Lots of customers are very confused with the bearingdesignations / part numbers. They can not get enough exact information which they want to know by reading the bearing designations. Although there are some differences among the main bearings manufacters’ designations rules, like SKF bearing, FAG bearing, NSK bearing ect. They still all follow some principles. This article will show you some of these basic common regulations of bearing designations. After reading, maybe you can get the knacks.
 
  Bearing designations can be identified as the following table:
 
  xxPrefix
 
  xxxxxBasic Code(Bearing series & bearing core)
 
  xxSuffix
 
  The alphabet before the basic code is known as “prefix”, while the alphaber after the basic code is known as “suffix”.
 
  The basic code is the same for all brands as they are guided undr the ISO standard. However, for the prefix and suffix, each bearing manufacturer may have their own part numbers as this is not guided under ISO.
 
  Prefixes for parts of standardised bearings:-
 
  K
 
  Cage with rolling elements
 
  L
 
  Separable ring of roller bearing
 
  R
 
  Separable ring with rolling elements of roller bearing
 
  WS
 
  Shaft washer of a thrust bearing
 
  GS
 
  Housing washer of a thrust bearing
 
  Basic Bearing Code:-
 
  Type of bearings
 
  Bearing series
 
  Deep groove ball bearings
 
  160, 618, 619, 60, 622, 63, 623, 64
 
  Angular contact ball bearings
 
  72B, 73B, B719, B70, B72, 32B, 33DA
 
  Four-point bearings
 
  QJ2, QJ3
 
  Self-aligning ball bearings
 
  12, 13, 22, 23, 112, 113, 115, 116
 
  Cylindrical roller bearings
 
  N2, N3, N4, NJ2, NJ4, NJ22, NU2, NU3, NU4, NU22, NU23, NUP2, NUP3, NUP22, NUP23, NN30, NNU49, NCF29V, NCF30V, NNC48F, NNF50.
 
  Tapered roller bearings
 
  302, 303, 313, 320, 322, 323, 329, 330, 331, 332
 
  Spherical roller bearings
 
  213, 222, 223, 230, 231, 232, 233, 239, 240, 241
 
  Thrust ball bearings
 
  511, 512, 513, 514, 532, 534, 522, 523, 524, 542, 543, 544
 
  Cylindrical roller thrust bearings
 
  811, 812
 
  Spherical roller thrust bearings
 
  292, 293, 294
 
  Needle roller bearings
 
  K, HK, BK, NK, NKS, NKJ, NKLS, NA, RNA, NAO, RNAO
 
  Bore Diameter (d) in mm 
 
  Generally we can take the last 2 digit of the basic code to know the d (bore diameter of the bearing).
 
  For example, the part number 6205, the d (bore diameter) will be 5 x 5 = 25mm
 
  For part number 6011, the d (bore diameter) will be 11 x 5 = 55mm.
 
  There are however some exceptions.
 
  For the basic code ending with 00, 01, 02 and 03, the d is as follow:-
 
  00 = 10mm
 
  01 = 12mm
 
  02 = 15mm
 
  03 = 17mm
 
  For the basic code with /xxx, the d will be the same as xxx. For example, xxxxx/500, the d will be the same at 500mm.
 
  Samples of some suffixes:-
 
  K
 
  Bearings with tapered bore
 
  E
 
  Bearings with maximum load carrying capacity
 
  ZR; .2ZR
 
  Bearings with one or two metal dust shields
 
  M, M1
 
  Machined brass cage
 
  TN, TV
 
  Polyamide cage of PA66
 
  P2
 
  Precision tolerance < P4
 
  S1
 
  Bearings for operating temperature up to 200 degree celcius
 
  Examples of bearing designations
 
  629
 
  62 = Deep groove ball bearing, series 62
 
  9 = Bore size (d) 9mm
 
  6001
 
  60 = Deep groove ball bearings, series 60
 
  01 = Bore size (d) 12mm
 
  6304
 
  63 = Deep groove ball bearings, series 63
 
  04 – Bose size (d) 04×5 = 20mm
 
  NJ2211E.TVP2.C3
 
  NJ22 = Cylindrical roller bearings, series 22
 
  11 = Bore size (d) 11×5 = 55mm
 
  E = Bearing with maximum load carrying capacity
 
  TVP2 = Moulded cage of polyamide PA66
 
  C3 = Radial clearance larger than normal
