Heavy duty polar mount prototype 1

Blimey your buggers:-rofl2, i will know more about these joints than anyone soon:-lol.

The best way to tell a ball joint from a spherical rod end is that the head of the ball joint stud is never visible in the assembly :-biglaugh.

That does surprise me. I used to do a fair few miles (16k a year) on my FZ600 and used either chain lube or a scott oiler and the chain still wore out after about 8,000 miles.

If WD40 works for you then continue what you are doing.

You know what you are doing wrong then ;) WD40 will make the chain more difficult for things to cling to. Spray on once evey other day, plus when you have returned from a rainy outing.

Scott oilers are good but only when set up well (the vacuum ones are the best but are still a pain to get right), chain lube collects all sorts of road dirt and if you haven't cleaned the chain off beforehand this acts as grinding paste, wrecking the links within a few hundred miles

That looks exactly like my pm that came with the PF Precision dish. Will probably use it for whenever I get the 1.8m CM... It's very sturdy.

My mistake, that is the Precision polarmount, I will get an image of the IRTE version sometime tomorrow.

Are you saying this new polar mount will go like 'Greased Lightning'?.....but is it the 'one that he wants'?
 
Tad expensive Martin, you could buy four sph......oh dammit...
 
Yes it is expensive pete, but I need quality and as we all know you have to pay for it, the steal for the mount and bolts only cost £30 so even if I paid £150 for two bearings its still only my time.
 
Not sure if that type of bearing is suitable for the direction of load that it will be subjected to. I think that type is for rotating shafts whose load is at 90 degrees to the shaft. The way, I guess, you would be using it it would be putting force in line with the shaft.
I think the joint you previously posted might be more suitable.

PS if you want that type of bearing then search for pillow bearing. They start at about £10 for one for a 1" shaft. http://www.wychbearings.co.uk/ucp205-16_housed_bearing_ldk.html?gclid=CP3RvJWUtr0CFdHLtAod-UEAHw

If Martin decide to use a http://www.amazon.com/UCP205-16-Pillow-Mounted-Bearing-Diameter/dp/B002BBQAK0
: The bearing has a dynamic (radial) load rating of 14 kN and a static (axial) load rating of 7.85 kN.
You have to use 2 of them , makes axial load 15.7 kN
That means ± 1600 kg . That wont be a problem .
UCF205 is the flange model .

Even a F204-12 will do: static (axial) load rating of 6.65 kN

That's great thanks, I will use them on all moving parts and re-design the mount, so all parts can be an easy fix and maintained for when I get older.
 
Loving the build buddy ..
A lot of thought going into it..and plenty overkill ..(which I like)
Should last you a lifetime..
I'm suitably impressed mate.

Axial loading is only additive if two bearings are on the same end of the shaft, i.e. supporting the same point. In this case the bearings are on opposite ends so radial load bearing is what is doubled, not axial.
 
Whats the difference ? they are on the same shaft , so both counts .
In practice the axial load can even be more since the bearings are tilted to the polar axis .

Sigh. If I got a lorry and put a lorry wheel on one end of the axle and a bicycle wheel on the other end the load bearing capacity before failure would only be as strong as the bicycle wheel. That is because they are on opposite ends of the shaft.

Also I think you need to look up the difference between static and dynamic load, because it certainly doesn't translate into radial and axial.
 
Martin! Maybe your son in law has something like this in stock? Could be expensive but replace mount and actuators.
