anyone know bearing size on ski trailers?

[tirone]

im going on a trip and would like carry some spares. i assume they are either 1" or 1 and a 1/6". i have a single- nationwide.

Mine are 1 1/16" but I bet they vary brand to brand.

Clean off the inner and outer bearing. There should be a series of numbers on there...something maybe like 624969. Take them to a bearing wholesaler or most local marine dealers even and match up the numbers. It's the easiest way to know you're getting exactly what you need.

My Triton trailer bearings are 1'' so be sure you get the right ones.

i went ahead and pulled one of the hubs and they are 1-1/16. walmart sells them for about 12 bucks a set with seal. made in china of course. one thing i noticed that i havent seen before, the grease fitting is screwed into the end of the spindle with a passage thru the center to get grease to the inner bearing. that seems like a pretty good design.
