Precision Ball Bearings
Shielded
For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings.
Shielded bearings dissipate heat more efficiently than sealed bearings.

Flanged Ball Bearings
The flange ensures proper positioning inside a tube or housing.
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.
