Only guaranteed quality can satiate customer’ needs, KMR stick to “best services derived from best quality” as the motto, cherish the bearing quality as the lifeline, never cut some slacks on QA/QC since day one.
KMR is authorized by ISO9001:2010, Each piece of bearing from KMR meet DIN standard;
KMR bearing steel procured from xingcheng special steel works co., which is the largest special steel rod, wire, plate manufacturer in the world, the main bearing steel supplier of SKF, SCHAEFFLER, NSK, JTEKT, NTN,TIMKEN etc. The purity: adulterant length<10μm; fatigue load limit>900MPa, 3 times of normal bearing steel.
49棋牌app Nevertheless, each piece of KMR bearing will undertake 18 testing procedure in the production. KMR will test the bearing material from appearance to slice cutting in physic & chemical analysis laboratory, analyze the element composition and structure grade to avoid the material flaw, each testing procedure will undergo twice testing, before and after the procedure to assure the quality.
AICHELIN heat treatment line is imported from Austria which is also used by SKF, the state of art heat treatment equipment secured the hardness, and anti-friction, increase the fatigue load limit, extend the bearing service life.
