Rose joints - which?
Hi!
I'm considering using rose joint at rear IRS. Of course, it depends a lot on individual design, but which rose joints do you use? What diametter
should I aim for and what about those load figures? I can get bearings from SKF here locally, so this is my preferred options. They have a range of
maintenace-free rod end - are those good?
Thanx,
J.

Marc at MNR might be the man to ask as he uses them on his cars and is very helpful and knows his stuff.
HTH,
Rich.

If your going metric on them. These prices are very good.

I bought 16 14mm male rod ends including shipping from the States to Canada for 75$ Canadian --there was 25% sale at that point but it beats anything
up here.

For a start I would strongly recommend using UNF rod ends, not metric, simply because the price for the metric ones is so much more for the same
size.
"National" ones are cheap and decent quality, made in the USA (as they nearly all are!) and available in the UK through Rally Design,
Randall Motorsport, Racers Hardware and Trackstore, amongst others.
Use the basic clubman spec, teflon lined Chrome-Moly ones, plenty strong enough and not too much more than the mild steel ones.

Steer (pun intended) away from the "economy" rod ends unless you're prepared to do the sums on them.
Mild or CroMo steel bodies with PTFE liners offer good service and precision. The CroMo ones are usually two to three times more expensive than the
mild steel ones and stainless are more expensive again.
I haven't found much difference in price between metric and imperial, probably because more US makers like Aurora list a full compliment of them
in their catalogue. Aurora are probably the world's largest producer and they list ISO fine threads too.
As you're in Latvia though, you may have more luck sourcing European rod ends at the right price. There are dozens of German and Italian
manufacturers of high quality rod ends with extensive catalogues.
If you stick with SKF locally, (very high quality metric rod ends BTW), their rod ends are metric and I'd recommend their glass lined SAKB 10F
and SALKB 10F joints. They'll probably be more costly than other brands though.

Thanx guys!
I'm definately not going for imperial ones, although those might be cheaper. Well, anyway currenlty I'll mostly use polly bushes - I need
just two rose joints for places where bushes are not suitable (angle change). So cost is not a major issue. I already use SKF SAKB16F for front so I
suppose that my choice was not wrong.
Just wondering - will those 12mm ones will be strong enough? SKF site claims 13.2 KN dynamic load. Sounds pretty much although I don't know how
to calculate actual load
