Let's get our bearings turning in the world

Better performance for maximum operation

Thin section bearings Manufacturer

Thin section bearings are a good solution for many modern product plans which require compact design and minimal weight. VDObearings is able to accommodate the shorter development time involved in the fast-paced nature of products implementing thin section bearings while maintaining a high level of quality and performance.

When a bearing has an inside diameter greater than four times the radial cross-section, it is considered a thin-section bearing. Special thin-section bearings are designed and manufactured when space constraints, combined loads and weight limitations are present. In any thin-walled bearing series, the cross-section remains constant as the bore diameter changes.

The thin-section bearings supplied by VDObearings have a small cross-section, multi-load capabilities, are lightweight, and have high stiffness.

Bearing data

The following is a small part of our company’s bearings, we also provide various types of thin-section bearings, if you need please contact us, and we will provide you with a special salesman to communicate with you.

Advantages of thin section bearings

Thin section bearings are designed to solve various design problems that cannot be solved by conventional ball bearings. Some of the advantages of VDO thin-section bearings are

  • Lightweight
  • Multiple load capacity
  • High stiffness
  • Variety of cross-sections and sizes
  • Small cross-section
  • Modified and custom bearings

The role of lubricated bearings

Lack of lubrication or inadequate lubrication is the most common cause of bearing failure.
Standard VDO thin-walled bearings are lubricated with oil or grease. The grease used for non-sealed bearings is different from that used for sealed bearings.

Lubricants have a number of very important roles in ball bearings, including

  • Protecting bearing surfaces from corrosion
  • Reducing rolling and sliding friction
  • Preventing metal contact between balls
  • Metal contact between raceways
  • Providing a barrier against external contaminants
  • Eliminates heat (oil)

Temperature conditions for thin section bearings

  • Standard VDO thin-walled bearings can operate at temperatures from -65°F to 250°F.
  • 350°F if the bearing is temperature stabilized.
  • By using special materials, VDO can provide bearings that can operate at 900°F.
  • Please contact your VDO sales engineer for advice on bearings that operate above 250°F.

Material selection for thin section bearings

Standard bearings are available with SAE 52100 steel rings and balls.
VDO thin-section bearings can be manufactured with other special bearing steels to provide corrosion resistance, high-temperature capability, high-temperature capability, or chemical compatibility.
VDO has fabricated thin-walled bearings from SAE 440C stainless steel to provide corrosion resistance, achieving a molecular bond that will not flake or separate from the base material.
Some special ball materials include 440C stainless steel, 300 series stainless steel, silicon nitride, M-50 steel, and nitride and M-50 steel.

Application Areas

Some typical applications for standard VDO thin-section bearings include. Thin-section bearings are often used where space, weight, and load constraints are encountered.

Other Features

Mounting Features

Thin-walled bearing itself high density, not suitable for strong stamping, not to mention the hammer directly hit the bearing, will directly damage the bearing.

Ultimate Speeds

The ultimate speed of a bearing depends on many different factors, including bearing size, bearing type, ball separator design, lubrication, and load.


The cage is to prevent the rolling elements from colliding and rubbing against each other during operation; VDO offers two choices of cage materials: brass cage as well as nylon cage.
