NSK deep groove ball bearings 6312 ZZ 2RS Automotive bearings
60*130*31mm
Description:
Materials for bearing rings and parts largely determine the
bearing's performance and life. FLATE/FUDA puts more efforts to
select materials for bearing rings and part suppliers in a rigorous
manner.
Materials and components of bearing rings for FLATE/FUDA bearings
are provided by the world's top suppliers special for serving
bearign manufacturers, fundamentally solvign the issue that our
bearings lag behind imported bearings in terms of materialsfor a
long time.
FLATE boasts a set of strict and polished incoming goods inspection
system. Before being put into storage, every batch of steels and
parts is under systemic inspection, including analysis of material
composition, metallographice analysis, accuracy check, assembly
test, etc.
