I was thinking about going with a linear ball slide Z-axis and was curious about some experiences from the users on the forum with regard to usage and durability.

My initial thought is a 20mm unit with 2 pillow blocks per rail and an approximate length of about 20". Something similar to theses (20mm Linear Shaft 55" Long 2 Slide Units 2 Shaft Supports Linear Motion Kit: VXB.com Ball Bearings)

What can I expect with regard to side-play and backlash?

Are bronze bushings a better choice?

Anything I'm overlooking that might tell me to look elsewhere?

Thanks as always for your input.
