I’ve seen on the forum off and on that with green bearings the inner seal is not needed. Seen different opinions on the subject, any ideas?
The green bearings are permanently lubricated, so they certainly don't need gear oil. Run it like you want. I know how I will run mine.Isn't the purpose of the inner seal to pack bearing grease in for the tapered bearing? Basically separating gear oil from the grease.
Technically, yes, but I think it is a mote point. There are many rear axles that use a "ball" bearing as OEM. Just as there are many rears that use a flat roller bearing that rides on the raw axle shaft, and has no resistance to side loading (uses the bearings on the carrier)Are not the Green bearings weaker on side load and not as desirable as
stock bearings for a street driver?
That is what I heard years ago.
I run them on the race cars and never had an incident and no seal.
Agreed. With green bearings, in my opinion, can't hurt to use the inner seal, but not required.We've been down this rabbit hole before. Think how many MILLIONS of vehicles use green type bearings. Purt near ALL front wheel drive cars do and a LOT of rear wheel drive vehicles, too. But let's keep this on track, because the OP wanted to know about the inner seals.
