Is this Linear Slide capable of handling 100pounds

[pinakbeth]

Can someone decipher this specs for this slide and truck combo. I don't have any engineering competence. Can someone explain in layman's term?

1 What is Dynamic and Static load ratings?
2 How much pounds can this thing handle?
3 What is Static Moment?
4 If I use this on my self built steel frame, will it be rigid enough to cut steel?

ill respond just so you will look at the post again, something happened and as you can see your original post doenst show up.

I was wondering if this slide and truck capable of handling 100 pounds?http://www.vxb.com/page/bearings/PROD/LM/Kit7429



There is specs but I don't quite understand the abbreviations. I don't have engineering competence.

My goal is to build a very rigid machine to cut metal, both soft and hard.

I have read some of the caveats regarding a steel cutting mill, and I am not yet fully discouraged.

I am still doing my homework, so any help will be greatly appreciated.

Most of the comments I've read discourages one not to build a DIY steel cutting CNC. As for most DIY plans appear to be for would and aluminum.

I live in Hawaii and getting a mill is costly in shipping. And building my own may as well be worthed.

Thanks

yeah they are all there now. I looked at that link you included. those rails are plenty plenty for a home built machine. the weight rating of a rail like that is more in the thousands of lbs rather than the hundreds of lbs. any play that it had would be extremely small if any. It may not be the highest quality brand, but id feel safe to say that they will do what you want plus a few times more.

I'm no expert but I'll make a stab and someone who knows more can tell me where I'm wrong.

1 What is Dynamic and Static load ratings?
As far as I know, static = constant force. dynamic = force that is present then released again. So static is the weight of the machine, dynamic is weight of machine plus cutting forces.

2 How much pounds can this thing handle?
2600 static. You're fine.

3 What is Static Moment?
This is "turning force", specified around three different axes. Hard to say how this affects you without full specs for your machine, but you can calculate it by multiplying the force by the distance. This is 18 Nm worst case (about 13 lb feet in American).
Eg force = 4lb, distance = 2feet. That's a torque (turning force) of 8 lb feet on the truck, which is ok.
If you have a gantry type system, you'll get negligible torque loads so long as all your forces are between the trucks, your frame is nicely aligned, and everything is stiff enough. If your trucks are far enough apart, the torque loads become side or vertical loads and everything gets stiffer and stronger.

4 If I use this on my self built steel frame, will it be rigid enough to cut steel?
Depends on how big everything is. Bigger = sloppier = more problems. You'll have to figure out some way to guesstimate the stiffness of your frame.
The stiffness isn't specified for those trucks (as far as I could tell), but should be fine for home use I would think.
