Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
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.

Flanged Ball Bearings
440C stainless steel bearings are more corrosion resistant than steel 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.
