These deep-groove ball bearings are more resistant to rust and corrosion than bearing steel ones are, and they can handle temperatures of -30 to 120 ℃ in normal use.
The material used for the inner/outer rings is KS440, which has equal hardness and corrosion-resistance to those of SUS440C but with better noise performance than SUS440C.
