Question: what is the inside diameter of these covers?
Document: I haven't installed these yet. I bought them as insurance against mine becoming lost at some point in time. I had another trailer which lost both covers and not only is there a risk of contamination from outside source, the grease came out the end and spread all over the rim. My granddaughter got grease all over her clothes. These are cheap insurance against contamination and ruined clothes.
These little covers are a great prophylactic against fluid leakage and loss of lubrication. Make sure you press them on fully before dipping your axle into any reservoirs. They come two to a package so you can do both ends at once, if you know what I mean and I think you do. I have no idea what I mean. Look, if you have a pair of Bearing Buddies - and really, who doesn't - then these help keep water and dirt out.
these are good covers, I leave out the cardboard piece because over time is falls apart and then you have to fish out chunks of cardboard out of the greese. I try to keep my bearing buddies full at all times (to the max) with tons of grease on the outside to minimize amount of space water can enter. I do suggest removing these frequently to make sure they haven't trapped any water and always top off your bearing buddies to make sure they don't seize, although I have the stainless ones which will never rust
just what i needed to fix my boat trailers brakes. and this was far better price than any other i found,.
i'll have to edit in a few years and let you know how they held up. working great for now!
easy to install. Hi quality of product making it one that is going to last as has several bought in past for other boats
couldn't get a good fit
Wish I knew that these came packaged with the Bearing Buddy. Now I have two sets because I ordered them when I ordered the Bearing Buddy, not knowing.
This product is just what you see and they work great. I would Definitely recommend for your all your maritime needs
These are very flexible and fit quite nicely, protecting the bearings from water and keeping the grease in the bearings.
Answer: no
