Default Re: NHBB Rod End's

i have done some more digging & found something that is interesting

i found this interchange chart for rod ends at the bottom of page 10 in the NHBB Catalog

http://www.nhbb.com/assets/pdfs/catalog/Racing.pdf

NHBB ................. Aurora

ARHT-ECR .............. PRXM-T


the load rating on the NHBB is 24,300 Lbs as we first had but the load rating on the Aurora is 25,909 Lbs

the Aurora info can be found here for the PRXM-T

http://aurora.thomasnet.com/viewitem...ned?&forward=1


it is the Aurora XAM Series that has a 40572 Lb rating that brings me to another question:

what is the better Aurora rod end to use for a 4 link the PRXM-T ot the XAM series rod ends

regards
rod

After some research I believe that the following applies: the Stainless Steel Materials used by NMB/NHBB are superior in terms of fatigue strength. SS also offers some corrosion protection. This is supported by the fact these materials are used in the aerospace industry extensively. The anomaly in strength differences for the XAM Series Aurora rodends stems from the fact that these ends use the larger size head with the next size smaller bearing while the NMB/NHBB use the smaller bearing head with a larger shank - hence the strength difference is due to the geometry not the material. In terms of strength I believe the two are basically equal - chromoly vs precipatation hardened stainless. In my opinion, a drag race 4 link, particulary the upper bars that are in tension, should address axial radial load strength and fatigue is a secondary consideration. This is the reason you see the recommendation by some that chromoly rodends be used in the upper links and lesser strength carbon steel can be used in the lower links although I wouldn't recommend this. Considering the expense of the NMB/NHBB I would say that the Aurora XAM series without the teflon liners (there isn,t much motion and no need to worry about pounding out the teflon) would be the best choice. Jerry Bickel uses Aurora bearings so they can't too bad. If a ladder bar front rodend then the bending load and fatigue would be the primary requirements: the bending maximum stress occurs in the threaded shank where it screws into the bar end so that radial strength would be a lesser concern - a NMB/NHBB would be my choice here. Certainly, a road race suspension application would require the maximu fatigue strength and thence the reason all major turn-racers run them. FK and QA1, as well as others sell rodends that are used apparently with success also. I hope I didn't drag this out too much - just my humble opinion!!!

Default Re: NHBB Rod End's

thanks for the info Leon

i have bought the NHBB rod ends for my car

i based my decission on a few things

1/ the car has run very successfull for the last 10 years with NHBB rod ends

2/ if the rods ends are stronger that the 4 link plates or bars it will damage them long before i hurt a rod end

3/ the old NHBB rod ends feel a lot nicer than a New Aurora ( not that there is anything wrong with Aurora )

4/ Lamb Components carry the NHBB in stock & they are great to deal with & will send parts to Australia

thanks again
regards
