1 Scope

GB/T 25765-2010 is the Chinese national standard on rolling bearings - ball bearings for automobile transmission, in the field of mechanical systems and components. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 23 December 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 June 2011.

The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the manual gearbox with ball bearings for passenger cars (hereinafter referred to as bearing) code method, structure type, technical requirements, testing Methods, inspection rules, marks and rust-proof packaging. This standard applies to bearing the production, testing and acceptance.
