[HELP] Steering link question

[Mechbuilds]

What's the difference between the steering links with or without stoppers?



Does the stopper mean that the ball can't go trough the link? 
I'm asking because i need to buy these links and the one with the stopper is 50% cheaper. 

If i got this right, the non stopper version lets an axle go trough it and the stopper version is strictly for ball studs?

That with stoppers, have some limitations on angle.

Thanks!

Maybe that wouldn't be biggest problem in most cases, but in that link with stops, it is possible insert ball pins only from one side, on each end.

So, this won't be possible

[Jurss]

With force it is possible to do different things, that is not meant to do so ...

If the steering link is going to be installed so both the balls enter from the same side, will the stopper one be more durable? Especially when the steering linkage will be taking most of the weight?

[TechnicRCRacer]

Pretty sure they are the same strength. From my experience, the ones with stoppers can only have ball joints inserted through one side.

[Leonardo da Bricki]

There is no difference in strength, as far as I can tell, and I have used both kinds for years.

Shouldn't this topic be in the general parts discussion thread?

I'm currently trying to make a spider walker frame. My first idea was to make a 4 legged walker. That proved out to be difficult since the walker would be a nightmare to balance. So then i thought about an 8 legged frame.. Well the normal strandbeest style leg frames are always fixed to move in 2d.. Then i found the sariel mini octopod walker frame. The frame has very natural movement paths on the legs. Plus they're worm geared so they stay in place. 
But the weakness of the frame is the fact that the whole weight of the model is being supported only on the links. 

Since i'm going to build a big spider like tank, the walking frame needs to be 12 legged in order to handle the 2kg weight. 
And since the weight is so massive, the legs need to be close together to reduce stress on the links. 

I tried searching for a walking mechanism that would make the legs move forwards and backwards AND up and down to give that 3d feel but there just isn't any other frames build this way. If somebody wants a walker frame, they build strandbeest style legs. 
I myself just can't figure out a mechanism that works this way AND is durable enough to be built wider and handle the weight. Not to mention have longer legs too. 


I've already decided to put the model in a stand to reduce stress on the leg mechanisms.
