Hmmmm....Preload and class. Well it's a Chinese build water cooled head. Unsure what the preloads would be but until I strip it (Work is busy at the mo and can't afford the downtime) I'll not know.

Perhaps I'll seek out some anyway and try them out.


Thanks for the reply

Typically you will get the hybrid types on machines where the races are steel and the balls are silicon nitride or carbide. The balls actually condition the races somewhat and the whole system works smoother with less friction even at near dry conditions.

Best of luck.
