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.

Electrically Insulated Ball Bearings

Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently. Shields keep out dust and contaminants.

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.

Mounted Ball Bearings

Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.

Bearings with eccentric lock have a collar that you twist in one direction to grip and the other to release. Compared to bearings with a set screw, they’re easier to install, require less adjustment over time, and are better for high-speed applications. But, they only work on shafts that spin in one direction.

Eccentric Lock Mount

Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.

Bearings with an eccentric-lock shaft mount are better than bearings with a set-screw shaft mount for high-speed applications, but only rotate in a single direction.

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.

Threaded V-Groove Track Rollers

External Hex Shoulder Drive

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.

440C stainless steel rollers offer better corrosion resistance than steel rollers.

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.
