About Plain Bearings

Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

High-Load Oil-Embedded 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 them to release a thin layer of oil on the bearing’s surface. Color is silver because of the iron. These bearings are also magnetic due to the high iron content.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Ultra-Low-Friction Oil-Embedded Sleeve Bearings

For applications with frequent starts and stops, the oil in these bearings contains particles of slippery PTFE that lubricate the bearing during startup.

High-Load Ultra-Low-Friction Oil-Embedded Sleeve Bearings

With extra iron and filled with oil containing slippery PTFE, these bearings support heavy loads that frequently start and stop along shafts. Startup friction causes a thin layer of oil to release onto the surface. Their high iron content also means they resist failing if their load suddenly and drastically increases, but they won’t run as fast as standard bearings. As sleeve bearings, they handle loads parallel to the shaft.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Food Industry Oil-Embedded Sleeve Bearings

The oil in these bearings is suitable for incidental contact with food. Startup friction produces a thin layer of oil on the bearing’s surface.

High-Load Food Industry Oil-Embedded Sleeve Bearings

Embedded with oil that is safe for incidental contact with food, these bearings are suitable for use in high-load applications such as bottling and filling lines in food processing plants. They are also known as Super Oilite® bearings. Startup friction releases the embedded oil onto their surface in a thin layer. Bearings are made of 863 iron-copper, which makes these bearings strong and resistant to shock loads.

Bearings with NSF H1 registered lubrication comply with NSF standards for incidental contact with food.

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.

841 bearing bronze bearings run at higher speeds than 863 iron-copper bearings. They’re also known as Oilite® bearings.
