Product Details

The QA1 MCOM18 is a metric COM series plain spherical bearing built for a wide range of performance and commercial applications. With an 18mm bore diameter, this bearing is constructed from premium alloy/chromoly steel — a step above the carbon steel used in many competing COM bearings — delivering superior wear resistance and extended service life.

Key Features:

  • Ball: 52100 bearing steel, heat treated, precision ground, and hard chrome plated for durability and smooth articulation
  • Race: Alloy/chromoly steel, heat treated, with a protective coating for corrosion resistance
  • Bore Diameter: 18mm (metric construction)
  • Outer Diameter: 42mm
  • Race Width: 16.5mm
  • No PTFE liner — standard dry-contact design (see MCOM18T for PTFE-lined version)
  • Sold individually

The MCOM series is QA1's most popular plain spherical bearing line, offering a traditional commercial grade design trusted in suspension, steering, and linkage applications across circle track, drag racing, street performance, and street rod builds.

I ordered an AEM intake for my F-150 on Christmas day and received it on the 29th. I would absolutely recommend this site to anyone looking for car parts - they had the lowest price by far and shipped fast. Great job!

very good price fast shipping

Great

Found Autoplicity by doing Google search looking for Corsa Sport Axle Back exhaust for my 2008 GT500. By far the best price, even cheaper than other big companies with free shipping by far. Ordered them on Thursday afternoon and got them 24 hours later in NY with the standard shipping. Could'nt be happier.

fast, polite service when we had a question

Ordering and paying with amazon was pretty painless.
