Ball Bearings
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

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.

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.

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.

Precision Needle-Roller Bearings
Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
Open bearings dissipate heat more efficiently than sealed bearings.
Shaft liners allow you to use the bearing on unhardened and unground shafts.

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.
Crowned rollers have a slight curve, which is invisible to the naked eye, to stay centered on surfaces that are not perfectly aligned and/or not perfectly flat.
Rollers with seal have end seals to protect rolling elements from dirt and contamination.

Shaft-Mount Track Rollers
Also known as yoke-style cam followers, these rollers have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end. Lubricate rollers through a hole and groove in the inner ring.
Crowned rollers have a slight curve, which is invisible to the naked eye, to stay centered on surfaces that are not perfectly aligned and/or not perfectly flat.
Rollers with seal have end seals to protect rolling elements from dirt and contamination.
