Selection Choices for Angular Contact Bearings

You are here: Home / Precision Bearings / Selection Choices for Angular Contact Bearings

Angular Contact Bearing Options

Applications have different bearing needs. Sometimes these requirements go above typical precision bearing specs.

For example, some may need:

  • Heavier load-carrying capabilities
  • Faster speeds
  • More flexibility for temperature fluctuations
  • So on and so forth

Applications with these needs probably won’t be satisfied by our stocked and “ready-to-ship” GMN angular contact bearings. That’s why we offer a variety of options to choose from in our angular contact bearing product line.

Our goal is to make sure every machine and application has the right precision angular contact bearing.

Find Your (Bearing) Match

Understanding our product label and part number will help spindle rebuilders, distributors and engineers recognize all the custom options available for order.

All customized options that aren’t widely available are manufactured at the GMN Germany headquarters and shipped to us in Houston, Texas. Our shipping turnaround times are very fast, usually the best turnaround times in the industry.
