Brand new drop-in replacement self-lubricating platter bearing system for Dual changers. A simple upgrade for increased playback performance.

The original bearing was designed mainly with record stacking in mind; a typical application of the era requiring a robust system to support records being dropped onto the platter. This multipoint thrust bearing system (as opposed to single point typically used today) was common and used by many manufacturers but in terms of audio performance however this design showed some drawbacks – the metal to metal contact between the hardened steel washers and ball bearing, rarely a good idea in hifi audio, required constant lubrication by the user and caused unwanted friction noise and rumble that can be heard during softer passages. To mask these problems one solution was to “seal” the bearing inside a cup filled with oil or grease which eventually oxidized and dried out.

Our changer bearings solve both these problems:

1. by eliminating any metal to metal contact within the system.
2. by being self lubricating (thanks to the MoS2 solid lubricant embedded within our bearing itself) without the need to add any lubricant by the user.

Combining this bearing kit with our idler wheel will improve two of the most influential mechanical noise sources and reduce low frequency rumble to its minimum.
