Objavljeno: 03.03.2006. 20:54      ako se ne varam ABEC je preciznost izrade lagera a ovo A ti znaci tvrdoca kotaca. sto veci broj stoji uz A to je kotac tvrdi.  Gost r3n@t0

Objavljeno: 09.03.2006. 10:53      Uglavnom uzimaj role koje ti imaju veci broj kraj ABECA....5 ili vise od 5,nemoj uzimat one kaj imaju 3 ili 1 ,al mislim da se te vise nit ne proizvode.Al opet imas u turbosportu set lagera abec 5 za 19 kn... A tvrdoca se izrazava s onim drugim brojem ,jedan ti je promjer kotaca (ono s mm) a drugi je tvrdoca( 76A,78A,80A,82A,...do, ja sam vidio max (86A) za role.Opet pise ti na njima outdoor ili indoor,i ovisno za koju vrstu rolanja....fitness,hockey,street...itd,itd. Za vanjsko rolanje najbolje ti je uzet 82A navise,nikako ispod,brzo ti se potrose... POzdrav  Gost Hrvoje

The system was developed by the Annular Bearing Engineering Committee or Council (ABEC) of the American Bearing Manufacturers Association (ABMA). The American Bearing Manufacturers Association was formerly known as the Anti-Friction Bearing Manufacturers Association. What Does ABEC Mean? The ABEC scale is a system for rating the manufacturing tolerances of precision bearings. The system was developed by the Annular Bearing Engineering Committee or Council (ABEC) of the American Bearing Manufacturers Association (ABMA). The American Bearing Manufacturers Association was formerly known as the Anti-Friction Bearing Manufacturers Association. Bearings rated under the ABEC system are typically called "precision bearings", and they are rated with a number from 1 to 9, with the higher number assigned to bearings manufactured against a higher standard of precision (high number = tighter tolerances = more expensive bearing). What Does Tolerance Mean? Tolerance is the amount of variation from an absolute exact measurement that is permitted during the manufacturing process. Other Bearing Rating Systems ABEC is only one system for rating bearing tolerances. The International Standards Organization (ISO) and the German National Standards Organization (DIN) use similar scales to rate the precision of bearings. In the ISO and DIN systems, a smaller number means a tighter tolerance and a larger number means a looser tolerance. This is just the opposite of the ABEC system. See the following table for equivalents. ABEC SYSTEM ISO SYSTEM DIN SYSTEM ABEC 1 Normal P0 ABEC 3 Class 6 P6 ABEC 5 Class 5 P5 ABEC 7 Class 4 P4 ABEC 9 Class 2 P2 Is ABEC Important for Skate Bearings? Here are comments about ABEC bearings from bearing manufacturers and other experts, including NTN, Miniature Bearings, Zero Drag, the Southeastern Skate Supply, and others.  Gost hadji
