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.

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.

Ultra-Corrosion-Resistant Stainless Steel Ball Bearings
These 316 stainless steel bearings are more corrosion resistant than our other stainless steel bearings, but they have a lower load capacity.

High-Load Plastic Ball Bearings
With two rows of balls, these lightweight bearings have greater durability and load capacity—and a wider profile—than single-row plastic bearings. They’re commonly used in bottle-filling machines and other food-processing applications. The acetal body doesn’t absorb water, so it can operate in liquids or be washed down without losing strength. The balls are made of either glass or 316 stainless steel—both materials are corrosion resistant. Since there’s no metal-on-metal contact between the balls and the body, these bearings don’t require lubrication.

Oil-Embedded Sleeve Bearings
Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Needle-Roller Bearings
Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.
Open bearings dissipate heat more efficiently than sealed bearings.
