Often the original idler wheels have hardened rubber and a worn bearing. These newly machined idler wheels are a direct 

replacement for the early model Rondine B-12, B-12GH, and B-12H that have the original metal body idler wheel.      

Machined from delrin, oil-embedded bronze, with replaceable O-ring to match the profile of the original idler wheels  

(o-ring is tight to the wheel and will not move freely). The bronze bearing is bored to .250", from solid rod stock to ensure a

tight tolerance fit to the idler shaft, while still spinning freely, this process along with the delrin body will help with some of

the rumble issues known with these turntables.
