180 groove or 360 groove rod bearings with spin pin

[jnava]

I was looking at the various combos of rod bearings and I see that 360 groove has benefits but I have a spin pin on the rods. So the 360 groove wouldn't work right since it actually wouldn't benefit. Plus, I can't seem to find a manufacturer that sells bearings for rods with spin pin, not even ffwd has them. Machined Most likely?

Are you wanting grooved bushings for the small end????

By spin pin, do you mean the wrist pin?


Or are you wanting a fully grooved rod bearing for the big end? It is not needed on the 4g crank since it is a cross drilled crank and every rod throw has 2 oil points.

Now if you are wanting to take down Magnus record of 1400HP then I can understand why you are looking for such things.

No, spin pin for aluminum rods. Rod bearings would have to be drilled for the spin pin and I was wondering if there was someone offering that option and I have found that Jay Racing has that option of drilled rod bearings. I've contacted them but have not received a response. They have ACL trimetal with the drilled option.

Ok gotcha!

A bearing location dowel.



Darren Up at FFWD has them in ACL coated.

No grooves in the bearing tho.
