The technology of thermal rolling expansion for large-scale bearing s forge pieces
whose outer diameter is less than 6 500mm, osmosis-promoting technology by chem-
cal heat treatment, and bearing s quenching technologies of Martensite and Bainite
with synthermal immersion of salt.
Advanced lathes, grinds, super-precise production line of numerical control and such
advanced technologies as combined grinding and one-off double raceway grinding
with a product precision higher than grade P5.
Testing equipment like three coordinates measuring instrument, optical profiler, round
ness instrument, etc, whose measurement accuracy is as precise as 2um. The type
test of bearings with a maximal outer diameter less than 3. 3m can be done.
Mastery of bearing s high-end coating technology by physical vapor deposition and
surface modification technologies like nitrogen treatment, vacuum vulcanization, etc
whose application dealt with the problem of early fatigue brought about by rolling sur
faces abrasion or burn due to the failure in formation of oil film when velocity is too
high or load is too weight instantaneously.
