Product Details

The QA1 MCOM20 is a metric COM series plain spherical bearing built for a wide range of suspension, steering, and performance applications. Featuring a 20mm bore, this bearing is constructed to commercial-grade standards while delivering enhanced durability over standard carbon steel alternatives.

Unlike many COM bearings made from carbon steel, the MCOM Series uses alloy/chromoly steel for the race, resulting in improved wear resistance and longer service life. The 52100 bearing steel ball is heat treated, precision ground, and hard chrome plated for a consistent, low-friction fit.

Key Features:

  • Ball: 52100 Bearing Steel — Heat Treated, Precision Ground, Hard Chrome Plated
  • Race: Alloy/Chromoly Steel — Heat Treated, Protective Coated for Corrosion Resistance
  • Bore Diameter: 20mm
  • Construction Style: Metric
  • PTFE Lined: No
  • Superior wear and longevity compared to standard carbon steel COM bearings
  • Stainless steel race available as manufacturer's option

The QA1 MCOM20 is the ideal choice for builders and fabricators seeking a reliable, long-lasting metric spherical bearing with proven alloy steel construction.

QA1 Suspension Bearing MCOM20

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

This is my second time ordering from Autoplicity and both times they had the lowest price on the items I was looking for (brake pads and CAI filter). Fast shipping, my filter was at my door two days later. Overall very satified.

I was amazed to find the air intake I wanted at the price offered by Autoplicity. No one else came close and the item was shipped very quickly. This store has been added to my favorites list........Thank You!!!!

I ordered a universal Hurst Pistol Grip "shift knob" for my '12 Mustang GT. It squeezed to a perfect fit right where I need to grip it. It improved shift time and accuracy greatly and feels and looks great! Autoplicity had the best price on the web and I got this in 3 business days. I recommend this product.

I received my Corsa exhaust for my Sequoia today; I had issues with Autoplicity with regard to the order/availability which once brought to their attention was rectified; in the end I had to wait a little longer than expected to receive my order but it was resolved and hopefully the management learned something from this experience.
