What is a thin section bearing?

A bearing of small cross section related to its diameter is called a thin section bearing. The aim of these bearings is to save space, decrease the weight of design and reduce friction. Thin section bearings are available in both inch and metric sizes and can be made of various materials such as chrome or stainless steel.

Thin section bearings have one thing special about them; each series has a constant cross-section which does not change as bore diameter increases. Standard dimensioned bearings, on the other hand, usually increase their sections when bores become larger. Such an arrangement allows for more compactness and lightness in terms of load carrying capacity making them very suitable where space is at a premium.

Thin-section bearings are characterized by low noise during operation but high precision required for production process as well as great load carrying capacity should be provided by such type products too. They come in different designs mostly with square cross sections that could be modified according to specific performance demands set forth within particular applications if necessary while being able to supply three basic types of thin section ball bearings: radial contact ball bearings, angular contact ball bearings and matched bearing sets upon customer’s request. Where accuracy together with reliability counts much (e.g., aerospace industry), they find wide application areas like robotics or medical equipment among others

Do You Have Any Question?

What is a thin section bearing?

Thin section bearings are a type of rolling element bearing designed for applications where space is limited. They have a reduced section height compared to standard bearings, allowing for greater clearance between the bearing and the surrounding components.

How does a thin section bearing differ from a standard bearing?

Thin section bearings have a smaller overall height than standard bearings, which makes them ideal for use in tight spaces or where weight reduction is a priority. They typically have a higher load capacity per unit volume due to their design.

What materials are thin section bearings made from?

Thin section bearings are typically made from high-quality steel for the rings and rollers, with a variety of cage materials available such as brass, phenolic resin, or polyamide.
