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.
