The advantages of stainless steel deep groove ball bearing:
1) AISI 440 Stainless Steel Which exhibit excellent toughness and hardness properties and offer good corrosion resistance. This material is used extensively in bearing applications where precise tolerances and surface finishes are required. Common heat treating may be in accordance with MIL6875. Stainless steel bearings are availabe in a variety of stainless steel material grade and compositions. Benefits of AISI 440c stainless steel bearings include: Withstand tough, corrosive conditions for extended service life, reduced maintenance costs and equipment downtime.The Corrossion resisteance is "very good",when 440 C Material is exposed to fresh water.(used in Fishing reel,Flying reel) and mild chemicals.This stainless steel material bearing is primarily used by world fishing reel manufacturers.
2) Miniature stainless bearins made from conventional 440 C stainless steel will be slightly noisy because the large carbides that normally concentrate at the grain bouldaries are exposed in the raceway fishing process.Bearings made from 440 series stainless steel can operate at higher temperatures than chrome steel,up to 250 degree continuous.Bearings made form this material are generaly 100% more expensive than chrome steel bearings.
