Product Details

The QA1 AIB12 is a commercial-grade AIB Series spherical bearing featuring a 3/4-inch inner bore diameter. Built from alloy/chromoly steel, this bearing delivers superior wear resistance compared to traditional carbon steel alternatives, making it a dependable choice for demanding suspension and rod end applications.

The bearing ball is manufactured from 52100 bearing steel — heat treated, precision ground, and hard chrome plated for smooth operation and long service life. The alloy/chromoly steel race is also heat treated and features a protective coating for corrosion resistance, with an oil coating applied at the factory. The AIB Series offers dimensions that differ from the standard COM Series, providing flexibility for a wider range of chassis and suspension builds.

Key Features:

  • Inner Ball Diameter: 0.75 in. (19.05 mm)
  • Inner Ball Width: 0.875 in. (22.225 mm)
  • Race Width: 0.687 in. (17.4 mm)
  • Receiver Race Diameter: 1.5 in. (38.1 mm)
  • Rod End Ball Diameter: 1.312 in. (33.3 mm)
  • Misalignment Angle: 10 degrees
  • Chamfer Reference: 0.030 in.
  • Ball Material: 52100 Bearing Steel — Heat Treated, Precision Ground, Hard Chrome Plated
  • Race Material: Alloy/Chromoly Steel — Heat Treated, Protective Coated for Corrosion Resistance
  • Sold individually

For applications requiring a self-lubricating option, the AIB12T variant includes a PTFE liner. QA1's AIB Series bearings are a proven upgrade for performance suspension builds where wear life and dimensional precision matter.

Excellent price and availability. Thank you.

Great experience with autoplicity. Fast shipping. Ordered on 5/31 got bed cover on 6/2. Fit truck perfect.

I was skeptical about Autoplicity since I hadn't heard of them before, and that their price was 12% lower than anyplace else I could find. Plus, I couldn't even find a store around here that carried the X-jack. Plus I got it delivered right This my door fast. You people are Excellent!

The best price found on the net for an Airtex fuel pump. Fast shipping via UPS. Received 08/09/2012<br><br>Autoplicity is now in my favorites. Order Number: <br>Ray J.

the shipping charges were high, but still cheaper than any place else with free shipping!

Very easy to order, updated regularly on status, great pricing and product
