Permanently Lubricated Stainless Steel Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

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.
Open bearings dissipate heat more efficiently than shielded bearings.

Self-Aligning Flanged Ball Bearings
No need to worry about precisely aligning these bearings—they swivel to compensate for up to 5° of shaft misalignment. The flange ensures proper positioning inside a tube or housing.
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.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.
Stainless steel bearings are more corrosion resistant than steel bearings.
