Green Bearings will work fine in 99% of the applications. The 1% that I know of is circle track or any heavy side load type racing. The green bearing will not live in that application. The tapered roller bearings are the only thing that can handle the side loads generated in this application. Before anybody chimes in and calls BS, don't, I build circle track cars and rear ends and have tested both bearings. The green bearings have failed in less than a year in this application. Some aftermarket axle companies actually make a different axle for circle track applications which comes the Timkin bearing. Moser is one of the companies, I Moser also has an option for a Timken tapered bearing on their other axles. Also even though the green bearing is an acceptable replacement bearing it is a fact not a myth that a tapered roller bearing will handle a higher load than a ball bearing. This is why the roller bearing was invented. Cars used to use ball bearings in the front hubs then they were converted to tapered bearings in the late 50's because they could handle more load. The reason you can't take an axle designed for green bearings and put Timken bearings on it is because the axles aren't long enough to make contact on the axle cross shaft buttons so you can adjust the pre-load. The green bearing to fit a Mopar axle came to life because of using spools. There is no cross shaft in a spool to adjust pre-load so a different bearing was need that did not require adjusting.
You shouldn't have any worries running a green bearing on the street. Also you guys shouldn't try and sell the green bearing with un-truths, it makes you sound un-intelligent.
If there is a myth at all it would be that a green bearing is just as strong as a Timken tapered roller nearing.
