Thin Section Bearings

What is thin section bearing

Thin section bearings, also known as slim bearings, are specialized bearings with a compact design, featuring a small cross-section relative to their diameter. This unique construction results in a lightweight, space-saving bearing that is ideal for applications where space constraints, weight reduction, and low friction are critical. Characterized by their ability to support radial, axial, and moment loads, thin section bearings maintain accurate and smooth rotation while catering to a diverse array of applications, such as robotics, aerospace, medical equipment, and satellite systems. The combination of precision engineering, minimized footprint, and versatile functionality makes thin section bearings an essential component in various industries, contributing to enhanced performance and efficiency.

Thin section bearings are designed for applications where space is limited, achieve extremely thin bearing cross-sections, as well as miniaturization and lightweight of products. the inner diameter range from 1.000" to 40.000" and the sectional dimension range from 0.1875" × 0.1875" to 1.000" × 1.000"，3 kinds open type thin section bearings are available: Radial contact (type C), Angular contact (type A) and Four-point contact (type X). 

The makeup of the thin section bearing helps to contribute saved space, saved weight, great running accuracy, and design flexibility.  These bearings are designed from a limited number of widths and thicknesses/cross-sections. The cross-section remains the same as the bore diameter increases.

THIN SECTION BEARINGS APPLICATION

Thin section bearings also have a wide range of applications, including medical equipment, robotics, Machine tools, Semiconductor manufacturing industry, construction equipment, food processing and textile machinery etc.

Common types of thin section bearings

Thin section bearings are designed for applications with space limitations and low load capacities. They are characterized by their low cross-sectional thickness and lightweight construction. Here are five common types of thin section bearings:

1. Thin Section Deep Groove Ball Bearings: These bearings facilitate small amounts of axial load in both directions and can handle radial loads. They are composed of an inner and outer ring, as well as a set of ball elements separated by a cage or retainer. Thin section deep groove ball bearings are known for their minimal friction and high-speed capabilities.

2. Thin Section Angular Contact Ball Bearings: These bearings are designed to handle both radial and axial loads but are primarily used for axial loads. They consist of an inner ring, outer ring, ball elements, and a cage, but are configured in such a way that the contact angle between the balls and the raceways permits greater axial load carrying capacity. When mounted in pairs, they can support loads in both directions.

3. Thin Section Four-point Contact Ball Bearings: These bearings can accommodate radial, axial, and moment loads simultaneously. Featuring a unique design with split inner or outer rings, they only have a single row of ball elements. The four-point contact ball bearings allow for a more compact design and simplified installation process in applications where space is limited.

4. Thin Section Crossed Roller Bearings: These bearings consist of cylindrical rollers arranged perpendicular to each other and separated by spacers. This configuration enables the bearing to handle radial, axial, and moment loads with high accuracy and rotational stability. They are ideal for applications requiring precise positioning and compact designs.

5. Thin Section Tapered Roller Bearings: These bearings are designed to handle both radial and axial loads but are predominantly used for carrying axial loads. They consist of conical rollers and raceways that create a contact angle between the two, enabling greater axial load carrying capacity. Thin section tapered roller bearings are typically used in applications with space limitations where higher axial load capacity is needed.

6. Thin section radial contact bearings:Thin section radial contact bearings are a subset of thin section bearings specifically designed for applications with low axial loads and high radial loads in limited space. Their slim cross-sectional profile allows them to be used in applications where space and weight restrictions are crucial factors. Thin section radial contact bearings can be found in various industries such as aerospace, robotics, medical equipment, and satellite systems.

There are key factors that should be considered when evaluating the Thin Section Bearings specifications for an application:
