Thin-walled bearings, also known as thin-section bearings or slim bearings, are designed with a smaller cross-section than standard bearings. These bearings are used in applications where space is limited and a compact design is essential. Thin-walled bearings are available in various sizes, primarily categorized based on their bore diameter, outer diameter, and width. The sizes of thin-walled bearings can vary widely based on the specific requirements of the application and the manufacturer’s offerings.

Common dimension ranges for thin-walled bearings

Thin-walled bearings

Bore Diameter: Thin-walled bearings can have bore diameters ranging from a few millimeters to several hundred millimeters. Small-sized bearings are suitable for delicate instruments and devices, while larger ones are used in industrial machinery.

Outer Diameter: The outer diameter of thin-walled bearings can also vary significantly, ranging from a few centimeters to well over a meter. Larger outer diameters are often used in heavy machinery and specialized equipment.

Width: The width of thin-walled bearings typically corresponds to the size of the cross-section. Thin-section bearings are characterized by their slim profiles, making them ideal for applications with limited space.

Thin-walled bearings

Series and Types: Thin-walled bearings come in various series and types, including radial contact, angular contact, and four-point contact designs. Each type is suitable for different load and speed requirements.

Material: Thin-walled bearings are commonly made from chrome steel, stainless steel, or other specialized materials, depending on factors such as corrosion resistance and load capacity requirements.
