I picked up some rails for a project, here are pics. That is a regular CD on the slide block. The rails are 7 feet long and weigh ~185lbs.

A better question is what sort of crazy machine are you using them on?

That must have been one great auction or someone was cleaning house.

I will be building a Bridge Saw for cutting granite slabs. Like on of these: saw

I only want to know two things about these slides, how much they costed new and the load rating?

[2muchstuff]

Are there any letters or numbers on the sides of the blocks.

[DennisCNC]

Yeah there are numbers:KA112006-2

I emailed THK they don't know what they are?

[2muchstuff]

If memory serves me right, THK uses 3 letters followed by a series of numbers.

It looks like SR series to me. Maybe a SR60W. I think these should cost from $4000-$6000.

I got the part number from THK they are SR85 and with a load rating of 27,000lbs

I remember reading in one of THK's pdfs that some of the applications for their rails include 'buildings'. These may be for just such an application.

Got a price on them also. One rail and one block is $2,200 made to order and shipping from Japan with 6 week lead time

You could make a small lathe out of one. Rail would be the lathe bed (cut down in length) and one bearing block would make a nice carrage.

[DennisCNC]

^^ Nice idea! But these things need to make me money first

Dennis, did you find the ballscrew yet?

If you want to see really big rail, check out THK JUP series. 9 inch wide rails, 780 tons per block. That`s like 2 Boeings 777

2k for rails like that isn't bad at all, it's easy to get over a thousand for one of the normal rails.

I was told by the THK western US sales manager that the Honda Motor Co. building in Tokyo Japan is mounted to THK linear guides for siesmic protection. each runner block is about the size of a 40gal oil drum, and the ball bearings are about 4" in dia.
