Product Details

Deep Groove Ball Bearings

Description
●The deep groove ball bearings are widely used in many industries.
●It mainly bears radial load and small axial load.
●Usually the material of the ring and ball is GCr15 (similar as AISI52100) chrome steel、AISI440c stainless steel or 20# (similar as AISI1020) carbon steel.
●For carbon steel bearings, after chemical carburization treatment, with a treated depth of 0.50~0.90mm, the surface hardness of the ring is about HRC58-61, while the cage is made of brass band (H62)、refined steel band (SPCC BQB402)、0.8F cold rolling steel band、stainless steel band AISI302、enhanced engineering plastics or phenol aldehyde.
●Shield is made of steel band (SPCC, ICr18Ni9) or cold rolling steel band.
●Seal is usually made of nitrile rubber, while fluorocarbon, silicone and teflon seals are commonly specified for high temperatures.
