carrier bearings melting down at a constant 70mph?


Recommended Posts

So I have been working on a project that uses a banshee carrier and axle to turn a motorcycle into a trike. So far it is coming together perfect but I am concerned about the carrier bearings. I am using Bearings that feature low-drag double lip rubber seals on both sides and have seals that go on the outside of them to keep the dirt and dust out. I know that these are made for a banshee that isnt really driving a constant 70mph for hours on end. I was wondering if anyone knows anything about this? I would hate to put this all together then have it melt carrier bearings while driving it.

i dont consider a banshee carrier all that good of a choice but theres a few things you can do. mainly add a grease zerk to the carrier and remove the inner grease seal off both bearings to allow the grease to get in there. i dont know if they ever made a carrier that will take 4 bearings and fit the stock arrangement. might be worth looking into. and check them regularly!

 

I do alot of fast riding on country roads and have never had a problem but im going less than 10 miles usually.

x2 on removing the inner seal and greasing the shit out of it.

twin row stock style

Yep, I've got an alluminum twin row stock style carrier on my son's bike. It does not have a grease zerk though. Easy enough to fix.

 

As for the bearings......none of the bearings out there were designed with the banshee application in mind. Meaning that bearingsare bearings and they aredesigned to do what they are designed to do. You get what you pay for with bearings and correct lubrication is a must for their proper operation.

There are three things that will overheat a bearing, excessive force, excessive rpm, and grease. I know a lot of people recommend greasing the hell out of bearings but it is a fact that more grease causes a bearing to run hot. I agree with above that bearings are bearings....within their rating class though. The higher the precision class, the faster the rating BUT the better the mating housing and shaft need to be to take advantage of that.

 

All that being said, at 70MPH, a 22" tire would be spinning a massive 90rpm! Even the shittiest of bearings with about any grease could do this as long as there is not excessive force on the bearings from misalignment.
