Product Details

The QA1 SIB6 is a premium SIB Series spherical plain bearing featuring a 3/8 in. inner bore diameter. Designed as QA1's top-of-the-line commercial spherical bearing, the SIB Series delivers superior wear resistance and corrosion resistance compared to traditional carbon steel alternatives — making it an excellent choice for performance suspension, steering linkages, rod ends, and other demanding applications.

Key Features:

  • Ball Material: 52100 bearing steel, heat treated, hard chrome plated, and precision ground for smooth, consistent operation
  • Race Material: Heat-treated stainless steel for exceptional corrosion resistance
  • Bore Diameter: 3/8 in. (0.375 in.)
  • No PTFE liner — metal-to-metal contact construction (PTFE liner version available separately as SIB-T Series)
  • Offers better wear characteristics than standard carbon steel spherical bearings
  • Sold individually

For applications requiring a self-lubricating option, QA1 also offers the SIB-T Series with an optional PTFE liner. The SIB6 is an ideal upgrade for motorsport, custom suspension builds, and any application where long bearing life and corrosion resistance are critical priorities.

Great Price fast shipping, I can't complain.

Great transaction. The bike rack was about $90 less than a local retailer, and shipping was faster than promised. I wish all internet retailers were this reliable and useful.

I ordered a part that did not fit, returned no hassles. I just ordered two items and hope they look great.

It was easy to order and the truck bed extender we bought was the lowest price we could find! However, the shipping charge was higher than what was posted on the comparison sight. Nevertheless, it still came in under the next highest price from a different vendor.

Order arrived quickly and was exactly as described. Great prices and service!

Very fast shipping and price is rite

User friendly

Fast service, great prices, highly recomended retailer.
