1.376" ID Bearings | McMaster-Carr

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.

Oil-Embedded Flanged Sleeve Bearings

Startup friction causes these bearings to release a thin layer of oil on the bearing’s surface. They’re flanged, so they handle loads both parallel and perpendicular to the shaft. They’re 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.

Precision Needle-Roller Bearings

Bearing

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.

High-Speed Oil-Embedded Mounted Sleeve Bearings

With Oil Cup

A strong steel housing allows these bearings to handle higher speeds than standard oil-embedded mounted sleeve bearings. Startup friction causes the bearing to release a thin layer of oil on the bearing’s surface.

Bearings with an oil cup have a reservoir that distributes additional oil onto the bearing. A self-closing hinged cover keeps out contaminants.

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.
