Sorry that i cant help you as i dont have any experience in profiled rails and carriages.
The rails that i mentioned in my first post are the only one that i have ever bought
So no experience at all ( other than the price and the dimensions of the rails that i have bought
I havent even use them in my machine

Wish you good luck

Hi Istvan,

Those prices seem a little high compared to what you would pay from China. Chai at linearmotionbearings sells PDF brand linear rails which are IMO slightly better quality than TBI for much less. The Flanged bearings cost approx $20usd, Slim type $19usd and the rails approx $39usd/per mtr.

Only up side with buying these rails for you is they are in your country. With Linear rails this doesn't really mean much has they are such simple components that the only trouble you could have is to loose balls or damage the plastic ball holders while fitting. In practise this doesn't happen often unless your very heavy handed. (Bearings will arrive on the rails from Chai so this is not a problem.)

I was looking at this yesterday. I'm going to buy some 6mm brass/copper grease pipe and some male stud couplings, elbows and tees and make it so there is just one greasing point per axis. I was thinking of doing it so that when the home command was given the axis all returned to the home position where the Z connected to the Y axis grease system and the Y axis connected to the X axis system so that there was just one point to lubricate...
