Lubricate track of straight line tracking tone arm


I have just set up a relatively mint condition Sony PS-X800 turntable with its straight line tracking tone arm.
What is the recommended lubricant for the track along which the short, straight tone arm slides?
WD-40 has been suggested, but I could find no reference in the online user manual as to any specific recommendation.
Any idea other than WD-40?
This unit is beautiful to look at, and is sounding surprisingly good with a seller-installed Grado Black "bottom of the line" cartridge.
The push button features are making it easy for any family member to play records.
But, need to get that track smooooth.

It occurs to me that graphite might be an appropriate non-gummy lubricant. I just Googled the Sony PS-X800 turntable and found it on vinyl engine where you can download the service manual. I just did and couldn't find anything about lubricating the bearing.
