SUS BEARINGS have higher resistance to rusting than SUJ-2 material bearings.SUS BEARINGS are good for high temperature environment uses.
 SIZE : SUS 600/6000/6200/6300 series.
Applications : machine parts which must endure high temperature  environments food machines,
for reasons of sanitation use in high humidity
environments prone to rust formation
