Special Dimension Bearings

AST can supply special bearings of all types including those with integral shafts that help reduce the tolerance buildup of mating components. Our engineers have designed bearings in a variety of configurations, special geometry, advanced lubrication, and high tech materials.

We can also provide precision assemblies manufactured to our customers' specific requirements. Other special bearings too numerous to catalog can be supplied such as:

  • Wire guide bearings with a radius (U Groove Bearings) or V grooves (V Groove Bearings) on the outer diameter
  • Bearings with split inner or split outer race (to control axial movement)
  • Spherical outer diameter bearings
  • Gyroscope quality bearings
  • Full ball complement bearings
  • Flush ground bearing pairs

Custom Bearings

The heart of AST Bearings is our ability to work with our customers on unique designs and applications. Since we provide only precision devices and related products, we are truly the precision bearing experts. Our team of design engineers and specialists offers more than a century of combined expertise.

We'll be happy to come to your facilities. We invite you to visit ours. Together we can create cost-efficient solutions to your most demanding specs, often with tolerances measured in millionths of an inch.

Our technical laboratory is equipped with the most up-to-date precision instruments and computerized equipment to evaluate bearing applications quickly and effectively. The unique "AST Bearing Analysis System" evaluates bearings from several perspectives, including load and speed requirements and environmental factors that may affect performance.

Our bearing engineers and designers can tackle virtually any custom bearing project including:

  • Custom ball bearings
  • Custom roller bearings
  • Custom bushings
  • Custom spherical plain bearings
  • Custom pillow blocks or flanges
  • Custom linear bearings
  • Custom rod ends
  • Custom thrust bearings

Let Us Help You

Send us the specs or samples of the bearings you currently use. We welcome the opportunity to evaluate the pros and cons and make recommendations accordingly. It is not infrequent that we can offer superior quality plus cost savings. This special program has been so effective that many bearing manufacturers themselves have used our services.
