Precision Ball Bearings
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.
Sealed bearings block out dust and other contaminants better than shielded bearings.

Flanged Ultra-Thin Ball Bearings
Flanged and creating twice as many contact points as angular-contact ball bearings, these bearings ensure correct positioning within a tube or housing and resist radial loads.
440C stainless steel bearings are more corrosion resistant than steel bearings.
Open bearings dissipate heat more efficiently than shielded bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
