Flange Extended Ring Ball Bearings(Stainless steel)
Flange Extended Inner Ring Ball Bearings is also called Flange extended inner ring bearing or flange wide inner ring ball bearings, it is a extended inner ring ball bearing with flange. Runstar has a full demension of stainless steel flange extended inner ring ball bearing or stainless steel flange wide inner ring ball bearings for choice, the stainless steel material can be 440(9Cr18),420(9Cr13) or 316 in Runstar. Compared with ordinary flange extended inner ring ball bearings with chrome steel,stainless steel flange extended inner ring ball bearings can keep from corrosion caused by some acids or moisture.The precision tolerance of stainless steel flange wide inner ring ball bearings or stainless steel flange wide inner ring ball bearings from Runstar can be from ABEC-1 to ABEC-9 for choice, Customized stainless steel flange extended inner ring ball bearings or stainless steel flange wide inner ring ball bearings are accepted for special applications. All stainless steel flange extended inner ring ball bearings from Runstar are strictly controlled under ISO9001:2015,with RoHs and REACH compliance.
