I have for sale a mint condition VPI TNT Mk V bearing. Arguably VPI best ever bearing and is a significant upgrade over the previous generation bearings.
The TNT Mk V bearing is made from 100% surgical grade stainless steel and weighs in at over 3lbs. Older TNT bearing assemblies weigh in at less than a 1lb and are made out of aluminum. Unlike the older bearings which utilize bronze bearing bushings, the Mk V bearing utilizes aerospace bushings made out of Rulon which is a self-lubricating PTFE material which results in less friction and a much quieter bearing. The MK V bearing is attached to the plinth using a 3 inch diameter stainless steel threaded collar that provides a much superior mechanical coupling over the older 3 tiny screw/bolts used in prior generations. In addition, the collar has a grounding screw to allow the bearing to be grounded thereby draining static electricity from the platter/album. You will LOVE this feature!
The Mk V bearing is a drop in replacement for previous generation TNT and provides a significant upgrade and is compatible with all former non-inverted bearing TNT platters.
I have provided pictures of the actual Mk V bearing for sale and for comparison, a Mk 3.5 TNT bearing.
The MK V bearing is no longer available from VPI and is rarely seen for sale. A must have for TNT owners.
