or the implementation of the National Standardization Technical Committee of the rolling bearing technology file 20The implementation of national standards: GB/T307.1-2005 spherical roller bearing rolling bearing or the implementation of National Standardization Technical Committee technical documents: CSBTS TC98.52-1997
GB is recommended, usually in the enterprise standard shall prevail, because the standard GB is the lowest threshold. CSBTS can be regarded as an industry standard, and has certain regional or industrial nature when implementing.
First, we should understand the two technical standards about the content: GB/T307.1 rolling bearing radial bearing tolerances, CSBTS and TC98.52 parts of rolling bearing ring surface roughness conditions, that is to say the specific content of the two standard is different, the roller bearing, GB/T307.1 is for inside and outside diameter and width of finished bearings, bearing the rotating precision and other technical parameters, CSBTS and TC98.52 are components for bearing ring roughness, for spherical roller bearings, the bearing design, the two standard is to do reference, can be said to be complementary to each other, and for the end user, because it only needs to reference GB/T307.1 can only consider the bearing outer diameter width.
No what to say, bearing the implementation of national standards: GB/T307.1-2005! Just national supervision basis! In addition, in 2005 the standard time is 1997 new, must according to the new standards!
