Currently, our miniature stainless bearings contains the following
Metal Shield Stainless Bearing Rubber Seals Stainless Bearing Open/Without Shield Stainless Bearing
Flanged Stainless Bearing Teflon Seal Stainless Bearing Ceramic Si3N4 Ball Stainless Bearing
Stainless Thrust Bearing YoYo Stainless Bearing Sealed Ceramic Ball Stainless Bearing
Bearings manufactured from a variety of stainless steel materials :
AISI 440C
AISI304
AISI316
AISI440B
Most of our stainless miniature bearings and thin section bearings are also available in 440
grade stainless steel 9Cr18. These are popular in the food industry, medical industry and in
high-temperature applications. We can also supply a customsized 316 grade stainless steel
bearings.
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.
Miniature stainless bearins made from conventional 440 C stainless steel will be slightly noisybecause 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 thismaterial are generaly 100% more expensive than chrome steel bearings.
If you want the most complete protection from corrosion that we can offer for your ball bearings,we recommends the freerun stainless steel ball bearings.
