Outer Limits 4x4 Board

does anyone know if these come in 36mm o.d. approx 35 i.d in 60mm or 30mm long and does anyone know how expensive they are. Also does anyone know of a web site.

they come in most sizes, CBC bearings stock them.
Give them the seal number and they will supply the sleeve to suit.

Hey cplux,

I got some from Central Coast Bearings on Manns rd W'Gosford. Give them a call on, 4324 4777. I found they're pretty helpful.

Or maybe try Gosford Bolts & Bearings, unit 3/24-28 Glennie St west. Nth Gosford. Ph: 4325 4216 or 4323 4236.

Hope that helps.

Always happy to help a local out!!

Cheers
Brighty.

they are ultra thin so you use the original seal for a given application - nowhere near 0.5mm thick. not sure if they come in a variety of lengths but normally only about 20mm - long enough to cover the grooves from a worn seal.

whats a speedysleeve - skuze my ignorance, but it sounds like a bit of bodgery. I like bodgery.

No bodgery involved - they are a sleeve of special steel that you install over a shaft or similar item, to renew the seal running surface. On shafts and the like the seal surface can become grooved from the seals, the sleeve fits over this worn surface.

I was about to ask the same thing. Thanks

is it stuck on - what stops it spinning?

As dumbdunce said previously... the speedi sleeves are less than 0.5mm in thickness. So when you tap them on using the cup toolie thingy they give you with it, it's a nice tight fit. This stops the sleeve from spinning, and gives you back the flat running surface for the seal.

The easiest way to understand it, next time you have a slight groove, lets say (hypothetically), it's on the axle where the axle seal runs. Get your vernier calipers out (or take the axle with you so they can measure it) and measure where the seal would normally run (not where the groove is)

You should be able to buy speedi's in most sizes, so call up ??? (most bearing places sell them I think)and see if they can supply you with one that size. When you pick it up, get the guys to open it and explain how to put it on. It's alot easier to show you than to describe it!!! But it does come with instructions in the box if you get lost.

If you are putting it on an axle you may need to drill, then cut the hole in the end of the cup tool with tin snips so as it can slide down the axle to where the speedi sleeve will be tapped on.

Once the sleeve is tapped into place, the last part is to cut a small nic in the leading edge (where you tap it on with the cup tool)and tear it away, leaving a nice new flat surface for the seal to run on.

As I said before, if the guys show you exactly what to do when you buy it, you shouldn't even need the instructions. It's just basic common sense.

Hope that helps,

Brighty.

They are a tight fit on the shaft and normally do not need anything under them.
I have seen them leak oil between the shaft and the sleeve and if the shaft has bad wear marks from the seal I have also seen them distort to the shaft wear. Loctite under them will stop these problems.

This what they look like
