Turntable Parts
 
Design:
-True Inverted construction. Ceramic ball bearing sits at the same plane as the drive belt, giving perfect alignment and bearing stability.
-Optimal lubrication. Oil feeder channels constantly push oil into the top section of the bearing for minimum rotational friction losses.
Hollow spindle allows adding lubricant from the top

Materials:
-nylon bearing plate at the top of the bearing case
-ceramic ball
-non-magnetic spindle
-non-magnetic phosphor bronze bearing case, nickel plating

the materials were chosen for their mechanical and tonal characteristics. This particular Japan-made phosphor bronze is very expensive and is used by a famous saxophone manufacturer, whose instruments are made from it in their entirety and are known for their deep rich tones. Remember that a turntable is a mechanical device and each material used contributes to it tonal balance - especially so the bearing.

Bearing fits 37mm thick platter, is 20mm in diameter and with a hollow spindle that extends 20mm from top of bearing.

Picture shows the bearing case before/after plating.

Includes: spindle, bearing casing, ceramic ball, nylon thrust pad, mounting bolt (extends up to 18mm for mounting in 1mm thick base)

I installed one in our well run-in demo BIX and had to turn back the speed a bit so very nice fit on these.

Re: Turntable Bearing
 
Brian,

have you computed prices for these yet? All I found was the blog entry on your website and no pricing or availability.

Thanks

Jeff

Brian do you have an image showing the mounting to a plinth, or at least a shot from the underside of the spindle with the mounting bolt fitted.

Thanks, very keen to try one in a new DIY deck.

This is what i can lay my hands on. 2 lengths of mounting bolts are available to allow different thickness plinth.
