What are the dimensions of flange screw bearings?

Flange screw bearings, also known as flanged bearings, are bearings with a flange attached to one side of the outer ring. The flange serves to accurately locate the bearing in the housing and provides additional axial support. Flange screw bearings are available in various sizes and configurations to suit different applications. The size of a flange screw bearing typically depends on factors such as the shaft diameter, bearing type, and load requirements.

Flange screw bearings dimensions

Shaft Diameter (Inner Diameter): Flange screw bearings are available in a range of shaft diameters, typically measured in inches or millimeters. Common shaft diameters for flange screw bearings include:

Metric sizes: 6mm, 8mm, 10mm, 12mm, 15mm, 20mm, etc.

Inch sizes: 1/4", 3/8", 1/2", 5/8", 3/4", 1", etc.

Outer Diameter: The outer diameter of a flange screw bearing depends on the specific bearing type and size. It is typically larger than the shaft diameter to accommodate the bearing housing.

Common outer diameters for flange screw bearings include:

Metric sizes: 16mm, 22mm, 28mm, 35mm, 47mm, 62mm, etc.

Inch sizes: 0.625", 0.875", 1.000", 1.375", 1.500", 2.000", etc.

Flange Diameter: The flange diameter refers to the diameter of the flange attached to the outer ring of the bearing. It is typically larger than the outer diameter of the bearing. Common flange diameters for flange screw bearings include:

Metric sizes: 22mm, 28mm, 35mm, 47mm, 62mm, 80mm, etc.

Inch sizes: 0.875", 1.000", 1.250", 1.500", 2.000", 2.500", etc.

Flange Thickness: The thickness of the flange varies depending on the bearing size and design. It is typically measured in millimeters or inches and can range from a few millimeters to several centimeters.

Bearing Width (Overall Width): The overall width of the flange screw bearing includes the width of the bearing itself plus the thickness of the flange. This dimension varies depending on the specific bearing type and size.

Bolt Hole Size and Spacing: Flange screw bearings may have one or more bolt holes in the flange for mounting purposes. The size and spacing of these bolt holes vary depending on the bearing size and design.

It's important to consult the manufacturer's specifications or datasheets to determine the exact dimensions and sizes of flange screw bearings for your application. Additionally, consider factors such as load capacity, speed, operating temperature, and environmental conditions when selecting the appropriate bearing size.
