Needle-Roller Thrust Bearings
Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings. Because of the large contact area between the rollers and washers (not included), these bearings are great for medium to heavy duty, low-friction jobs. For use on hardened and ground surfaces.
Washers allow you to use the bearing on unhardened and unground surfaces.

Chemical-Resistant Dry-Running Sleeve Bearings
These bearings stand up to a wider range of chemicals than other dry-running sleeve bearings.
Fiberglass-backed PTFE are strong and vibration resistant. A layer of PTFE on the ID of the bearing reduces friction.

High-Load Oil-Embedded Flanged Sleeve Bearings
Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes these bearings to release a thin layer of oil onto their surface. Color is silver because of the iron.
863 iron-copper bearings are also known as Super Oilite® bearings.

High-Load Food Industry Oil-Embedded Flanged Sleeve Bearings
Support heavy loads that are often found in bottling and filling lines in food plants—these bearings contain extra iron and FDA-compliant oil. The oil is safe to touch food, though it shouldn’t regularly come in contact. Startup friction causes these bearings to release a thin layer of oil onto their surface. They’re flanged, so they handle loads both parallel and perpendicular to the shaft.
863 iron-copper bearings contain more iron than 841 bearing bronze bearings, so they’re stronger and resist failing if their load suddenly and drastically increases. They’re also known as Super Oilite® bearings.
