About Ball and Roller Bearings

Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
Open bearings dissipate heat more efficiently than shielded and sealed bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Bearings with extended inner ring provide additional shaft support.

Precision Flanged Ball Bearings


When speed and accuracy matter most, opt for these bearings. They’re made to tighter tolerances than standard flanged ball bearings. All are 440C stainless steel for good corrosion resistance. The flange ensures proper positioning inside a tube or housing.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
