About Ball and Roller Bearings

Ball Bearings

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.

Bearings with retaining ring have a removable retaining ring that holds the bearing inside a housing.

Permanently Lubricated Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the 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 Ball Bearings

Shielded

Sealed

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.
