rose joints

I planning to use rose-joints at the Rear.

My IRS will have 2 M12 at the lower wishbone an 1 M16 at the top.

Which are best to use steel/steel, steel/bronze, or chrome/ptfe.

And are they in different shaft-lenghts?
In the book a have they are pretty short
M12 = 32 mm lenght of the tread
M16 only 37 lenght of the tread.
This doesnt' give me a lot of adjustable play.

Hi why use metric thread for suspension when every one else uses unf thread. Because it's a finer thread it allows for much more accurate adjustments to be made.

cheers matt

Spherical Rod Ends

Its difficult to say what is "Best"......

The metal on metal ones (steel or bronze) generally have lower stiction but any clearance will be felt as a rattle. They also require lubrication.

I prefer stainless / reinforced PTFE as these last a long time and do not rattle. I tend to use a larger joint (1/2" bore) for suspension as the bigger the joint the longer it will last (more surface area at the cost of increased stiction).

I use imperial because there is more choice and I can buy aircraft spec bolts very easily in imperial. I also have the left and right taps and reamers for the housings (if using spherical joints and not rod ends).

My favourite makes are Silver and Goldline, NMB E Type.......but there are many other good makes.

RE: MOT on a loose joint. Even a worn joint will have less play than a soft rubber bush, the problem is you an feel the play in a joint.
