Specification :

Email : jiahebearing@ gmail.com We can produce the diameter from 15mm~ 360mm single row tapered roller bearings, Following is the internal structure of different product descriptions we produce. B Steeper contact angle than standard design CLN Reduced tolerances for ring widths and total ( abutment) width; corresponds to ISO tolerance class 6X CL0 Accuracy to ABMA tolerance class 0 for inch bearings CL3 Accuracy to ABMA tolerance class 3 for inch bearings CL7A High-performance design for pinion bearing arrangements ( superseded by CL7C) CL7C High-performance design for pinion bearing arrangements E Enhanced design. HA1 Case-hardened inner and outer rings HA3 Case-hardened inner ring HN1 Inner and outer ring with special surface heat treatment HN3 Inner ring with special surface heat treatment J Pressed window-type steel cage, roller centre. A figure following the J indicates a different cage design P6 Dimensional and running accuracy to old ISO tolerance class 6, better than Normal Q Optimized contact geometry and surface finish R Flanged outer ring TN9 Injection mould window-type cage of glass fiber reinforced polyamide 6, 6, roller centre U. U combined with a one-figure number identifies reduced total width tolerance. VA321 Optimized internal design VA606 Crowned raceway on bearing rings and special heat treatment VA607 Crowned raceway on bearing rings and special heat treatment VC027 Modified internal geometry for increased permissible misalignment VC068 Increased running accuracy and special heat treatment VE174 One locating slot in outer ring at large outer ring side face, increased running accuracy VQ051 Modified internal geometry for increased permissible misalignment VQ495 As CL7C but with reduced or displaced tolerance for the outside diameter VQ506 Reduced inner ring width tolerance VQ507 As CL7C but with reduced or displaced tolerance for the outside diameter VQ523 As CL7C but with reduced inner ring width tolerance and reduced or displaced tolerance for the outside diameter VQ601 Accuracy to ABMA tolerance class 0 for inch bearings W Modified ring width tolerance, + 0, 05/ 0 mm X Boundary dimensions changed to conform to ISO
