The QA1 AIB-T Series spherical bearing is a heat-treated, chrome-plated chromoly steel bearing with a 1/2" bore and an internal PTFE liner for self-lubrication. It combines the wear characteristics of chromoly race construction with a low-friction PTFE lining to reduce maintenance in pivot applications. QA1's AIB-T option expands the AIB family where self-lubricating performance is preferred.
