Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
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 Stainless Steel Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating 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.

Thrust-Load-Rated Threaded Track Rollers
These rollers are rated to handle radial and thrust (top and side) loads simultaneously. 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. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.

Threaded V-Groove Track Rollers
Thread the stud directly into a component or secure with a nut for through-hole mounting. Rollers are for use with Angle Rails for V-Groove Track Rollers. They handle radial and thrust (top and side) loads and work well in dirty environments because debris falls off the angled rail. Also known as cam followers, track rollers support loads while guiding and positioning work. All rollers are permanently lubricated.
Rollers with a seal block out dust and other contaminants better than shielded rollers, but they hold more heat. Their seal also helps retain lubricant.
