608zz bearings for push chair

[Spare tyre]

Purchased a second hand buggy for my daughter, it’s been ok for 5 months or so. Something caught my attention re the front wheels, they are small 6 inch Jobbies where as the rears are probably 12 inch.

The buggy gets rough use, probably 4 miles a day, woods, fields, water mud etc

Each front wheel has two bearings, and one in each wheel has seized up, basically causing the whole bearing to spin in the axel, rather than acting as a bearing, the screw what holds the axle is has started to come loose from the buggered bearing

I took the bearings out and tried to improve things, but i can’t afford to immobilise it or I’m in trouble

Purchased these from amazon for delivery tomorrow, will they Be any good or are they cheap crap

Can anyone link me up with decent eBay / amazon bearings, ideally ones that are good with moisture


Going to lower it next, bigger rimz and a spoiler

You could try fitting a 608RS instead (RS = rubber seal, ZZ = metal seal).

Simply Bearings sell all sorts of brands including better quality stuff like SKF, FAG, INA etc.

Well the cheapies arrived

Wife took pram for maybe 2 mile walk, came home, noisy

Bearings had already seized, buy cheap buy twice

Off to Solent bearings in the morning i think!

Guess I need ones pre greased and with a rubber seal

Good skateboard bearings take a hell of a beating before they give up. I used to skate a lot when I was a kid, ollieing off 6ft high flights of steps, etc, and went through lots of bearings - but a set would last me miles and miles and loads of hard impacts. I'd look towards your axle, not the bearings - even a cheap set should last forever with a baby on it.
The axle used to be sleeved back when I was a nipper if the bearing had been slipping on it - just a bit of thin , tubular, slit stainless steel with a bevelled end, you slid it over pretty tight, then knocked on the bearing with a skate tool.
Or, you could be like my dad and insist on measuring tolerances etc. - then making me buy the finest Swiss bearings around, and removing them once a week and oiling them with white lithium grease... which of course he had researched ahead of time to find the right qualities.
Gret solicitor, great engineering mind, but ask him to actually DO something practical and he'd end up hammering screws through his thumb or something!

edit - "bearing savers" I think the sleeves were called, could be totally wrong though, it's been a while!

Edit2 - maybe "axle savers"?

Cheers for the info

So I went to the local bearing place this morning explained my problem.

They asked how much I wanted to spend, I asked for the mid range, which got me some rubber sealed jobbies that feel much nicer

Fitted them and did the same walk as yesterday and they are silky smooth

I opened up the internet bearings that seized after 1 outing and they appeared to be rusted up.

Buy cheap buy twice


I’m now considering replacing the rear bearings!

[guindilias]

Is there a spacer between them OK? You aren't squishing them apart by tightening them down? I remember skate wheels always had a bearing each side, with a metal bearing spacer on the inner races, so there was no sideways load on the inner race when tightening up.

The wheel acts as a spacer

Done another outing in the last couple of hours and it seems like problem solved

Think the initial replacement bearings had a good advert but poor product

Wish I’d just gone to the specialist first

Thanks all for your help
