Ball Bearings
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Bearings with retaining ring have a removable retaining ring that holds the bearing inside a housing.

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.

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.
