Product Details

The QA1 SIB3 is a commercial-grade plain spherical bearing from QA1's SIB Series, featuring a 3/16-inch inner bore diameter. The SIB Series represents QA1's top commercial-grade spherical bearing line, engineered for superior wear resistance compared to traditional carbon steel alternatives.

Key Features:

  • Ball: 52100 bearing steel, heat treated, precision ground, and hard chrome plated for durability and smooth articulation
  • Race: Stainless steel, heat treated for corrosion resistance and long service life
  • Inner Bore Diameter: 3/16 in.
  • Improved wear characteristics over standard carbon steel spherical bearings
  • Available with or without optional self-lubricating PTFE liner (see SIB-T Series)
  • Suitable for a wide variety of suspension, steering, and linkage applications

QA1 SIB Series spherical bearings are designed for demanding performance and motorsport applications where precision, durability, and corrosion resistance are critical. The stainless steel race combined with a heat-treated, chrome-plated steel ball delivers long-lasting performance in high-load and high-cycle environments.
