Product Details

QA1 Precision Products spherical bearings, also sold as spherical rod end bearings or heim-style bearings, are built for suspension and linkage applications that need smooth articulation and precise motion control. Each bearing has a PTFE (Teflon) liner, which reduces friction and gives consistent, low-maintenance performance.

Key Features:

  • PTFE-lined spherical design for smooth, low-friction movement
  • Allows angular misalignment so suspension links, control arms and rod ends can move through their full travel
  • Precision-machined construction for tight tolerances and a consistent fit
  • Self-lubricating liner reduces the need for routine greasing
  • Suited to street performance, racing, off-road and custom chassis builds

QA1 is a well-known name in suspension and chassis components. This bearing line gives builders and racers a dependable way to improve linkage precision and reduce play.
