Ultra-Slim thin section bearings have the thinnest cross sections in the entire SKF bearing portfolio and are a very compact solution for applications where space is limited. They are available in three different bearing types:

• radial contact ball bearings (type C)
• angular contact ball bearings (type A)
• four-point contact ball bearings (type X)

Kaydon standard Ultra-Slim thin section bearings are made of stainless steel and include spacer balls as separators. The bearings can be customized to meet specific application needs.​

Features and benefits

• Extremely thin cross section
  In applications where space is limited, Ultra-Slim thin section bearings offer a very compact design.

• Lightweight
  Ultra-Slim thin section bearings can enable significant weight savings, which may result in cost savings for the overall application.
• Corrosion resistance
  Ultra-Slim thin section bearings are made of stainless steel and are therefore corrosion resistant when exposed to moisture and several other harsh environments.
• Low friction
• High stiffness
• High running accuracy

Applications

The small cross section, large bore Ultra-Slim thin section bearings are designed for industries, at top of the list, and applications where precise positioning and lightweight designs are important, including:​ ​

• Aerospace
• Robotics

• Inspection equipment
• Satellites
• Other similar light and medium-duty applications with slow or intermittent rotation
