Rod end bearing without the angle movement?

[Wheazel]

Hi

I am looking for a similar thing to this:

BUT without the angular play. So basically a bearing on a stick. What is such a thing called? Still rod end bearing?

Thanks

try this link to IGUS rod ends

Why do you want it on a threaded rod?

In most cases, industrial manufacturers would use a pillow block unit rather than a stud mounted bearing. It's a lot more secure and imposes lower loads on the frame it's mounted to.

Those are sometimes known as Rose connectors and are used for tie rod ends in the steering mechanism. Both of our trikes have them for steering connections since they allow motion in 2 planes without slack. They go into threaded tubes, the tie rods. As Chalo states you would be better off using a fixed bearing for a guide that does not need flex, like for axle location with rotation.

thanks for the inputs, weight and size are the reasons for not directly settling on a pillow block.

I might lathe a smaller bearingholder and weld that to a rod as solution.
Also dont need it on a threaded rod, just a way to easily attach it to a chromo tube. Be it welding or screwing.

McMaster-Carr, maybe drill these out and press in a common bearing? (scroll down to "solid rod ends"):

putting a bearing on an end of a post like that would probably cause trouble. there is no suport for torque loads, and that style of rod end would still be heavy.

Pillow blocks Like CHalo showed are better because the wider base will support the bearing better from what ever side loads and torque the bearing would be under. The idea is to spread the load out over as much surface as possible for stability. But those blocks aren't light.

An alternative would be to use a flat piece of steel, cut to give support over a wide base, with a hole drilled to hold a flanged bearing like this: http://www.grainger.com/product/DYN...m/rp/s/is/image/Grainger/1ZFF7_AS01?$smthumb$

Those flanged bearings look like a great way to incorporate a lightweight bearing into the existing structure (maybe even into a CHS tube end).

If you do want a pillow (or flange) block bearing check out the pressed steel version - they're lighter and less bulky than the cast iron ones.

Thanks all, these suggestions solves my problems without excessive amounts of extra work and testing.
