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.

Food Industry Permanently Lubricated Stainless Steel Ball Bearings
Good for applications with incidental food contact, these 440C stainless steel bearings have a food-grade, solid polymer lubricant between the balls and ring that eliminates the need for additional lubrication. The solid 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.

Ultra-Thin Ball Bearings
These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.
Open bearings dissipate heat more efficiently than shielded bearings.

Threaded Track Rollers
Also known as cam followers, track rollers support loads while guiding and positioning work. Thread the stud directly into a component or secure with a nut for through-hole mounting.
Rollers with seal have end seals to protect rolling elements from dirt and contamination.
