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.

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.

Panel-Mount Ball Bearings
Unlike other ball bearings, these do not need to be fully inserted into a housing. A spline around the outside of the bearing creates a permanent, secure hold in thin panels. Bearings swivel to accommodate up to 5° of shaft misalignment. Shields keep out dust and contaminants. Not for use in plastic panels.
