Bearings?

I'm looking at the VXB.com web site and can anyone tell me if the bearings are a fiber casting outside or a full metal bearing. Better yet does anyone have the part or kit number. I spoke with a sales rep and she asked if I needed a fiber outside or full metal bearing.

The Bears :-(.

Ok, this is a forum topic for Chicago Bears fans (and really, all sports fans). Who thinks that the Chicago Bears are the most depressing team to be a fan of? I just got done watching the Bears/Falcons game. That was depressing. They had their chance to come back... and they blew it! Oh well, there's always next week.

How would I secure a 1/4" id bearing to a 1/4"shaft? The bearing slides on very easily and is a little sloppy. I bought these from a supply co. thinking a 1/4" id bearing would fit properly on a 1/4"shaft. Any one have and ideas?

Bearing/fulcrum for a pendulum

I want to swing a locket on a chain like a pendulum and I want to minmise the friction experienced where the chain attaches to the supporting post. What sort of bearing or similar device should I use for this? Ideally it should be available in a bronze/dirty brass colour but I guess I can deal with it if it isn't.

Low friction "bearings"

For several of my projects I required some sort of bearing that would not only allow for a minimised free play but also very low friction.Before you get too exited: This is not a new type of bearing or anthing for heavy duty loads, not even for ongoing use without servicing.I found that even slightly heavier things rotated on makishift bearing far easier if the axle was verticall instead of horizontally.This gave me the idea to try a simple needle-bearing approach.This is how it goes:1. Grind and polish your axle to get a nice needle point - it must be perfectly centered!I prefer to do this with the axle in a fast spinning drill on a fine grinder.The polishing in a simlilar way, but please do not try it with a cloth in your hand on a spinning axle!2. The other part of the bearing is a screw or pin with a punch mark.I grinded and polished a punch for this so it has an angle of 60° and polished it to a mirror finnish.If alignment is of importance then of course the pin/screw must work for this purpose!If in doubt make it spind an use a pencil to get the true center.A drop of sewing machine oil and it spins nice and with very little friction.The key is to adjust the gap(s) between axle and punch mark to next to nothing.You don't want any pressure along the axle as you would "drill" a hole into your mounts.And you don't want it too loose to avoid wobble.I hope it might give you an idea for your next project.

What to do with Ball Bearings?

For some while I've had a pile of ball bearings sitting here on my lounge room table, and without knowing what on earth to do with them, I now ask you. I have found uses such as adding to my "mousetrap racer," a small car, run by a mouse trap, that can go up to 15 metres. With ball bearings it goes twice as far as it used to, so I have become curious... what to do now though? All ideas would help, and an instructable would be even better. Cheers

Difference between a 608zz and 608 bearing?

I have started the swap to go to this extruder on my 3D printer. As such, I am taking the time to go ahead and use new bearings. I have a set of eight that came from a [one week old] skateboard someone broke, but they are 608zz. The BOM of the extruder calls for 608. From what I can see, the only difference is that the 608zz have a plate that covers the ball bearings, versus 608 which appear to be open. Is this true? and if not, what is the difference? Can I use the two interchangeable? thanks in advance!

How to stop oil going into a motor from the attached pump?

I am fighting a little war with some oil pumps.Attached to a 1/2HP motor the construction is quite simple.To prevent leaking there is a spring loaded oil seal between pump and motor.But this seal is never 100% if you deal with 180°C hot vegetable oil....At these temps the stuff is literally thinner than water and sooner or later finds a way out.Main problem I am facing is the drying of the vegetable oil.Over time it turns intoa really hard resin.But before that it manages to creep all the way into the motor bearing in the front part of the motor.It drives out the grease and slowly replaces it with drying resin util the whole thing seizes.Rebuilding is a true pain in the back as it is a 180V DC motor with build in rectifier and regulator to run on 220V AC mains.Things I tried so far:Adding a good amount of high temperature grease bewtween oil seal and motor housing - only a marginal longer service time was achieved.Making a custom sleeve to go over the motor shaft that is glued onto it - worked well, or so I thought until I realised the silicone oil content in the oil slowly destroys all gues I tried so far.Adding a shim disk right on top of the bearing - this worked best so far and almost doubled the time until the motor failed. Downside is that it takes me over 4 hours to fully rebuild a motor just to get said dik in and I have no replacements anymore.It was suggested to me to set the back of the motor slightly higher than the front so the oil would not go anywhere near the bearing.This I tried to implement about 8 weeks ago and as the motor got noisy last week I took it all apart for a service again.Despite the motor mounted at an angle of about 5° the oil still creeped past the shim disk and into the bearing.So I did some simple tests with the hot oil and indeed it forms a slowly creeping film tha travels upwards on a shaft.I guess the rotation helps here as well to spread the drops around.And yes, last time I used "fully sealed" bearing with an build in cover and still it fails :(I would love to try something flexible but long lasting to seal the bearing against the rest.Something in the region of a rubbery stuff that can be applied like a sealant.But hard enough to survive a few weeks of shaft rotations.Are there any really sealed bearings available?Bearings that, for example would be fine working submerged in liquid without any liquid being able to enter?It is clearly a desing fault of the machine to make money through spare parts but that's not the point here.I can not replace the pump as it is an intergral part of other things attached.And not really that easy to find a pump capable of dealing with hot oil anyway.Is there any grease available that does not turn into a liquid at these high temps and would it be possible to get ito into a bearing?Running out of ideas here guys, so feel free to throw in whatever comes to mind even if it seems odd!I just need a way to keep highly viscous, boiling hot oil from entering a bearing ;)

Problem removing a glued on bearing from glass

I am a bit stuck and usually this does not happen too often :(Got a lazy Susan with two glass plates and the bearing sitting in two aluminium disks.The thing still works fine but the plates were never really centered properly.Starts to drive me nuts that it is always "wobbling"...My first attempt was to figure out if the glue might just be hot glue, so I gently heated it all up.Was a not go but didn't expect it to be that simple.Next try was to use some clay around the aluminum disk and then fill the dam with acetone to dissolve the glue.It did not even soften it a bit :(To make it complete I also tried it with Methye Ethyl Ketone as it never failed me but it seems the glue used is chemical resistant.In terms of echanic tried with a thin bladed tool but can't get it into the non existing gap between glass and aluminium.And even braided fishing line seems to fail as after about 20 minutes of trying to get in the glue I got nowhere.My last resort would now be to put it in the oven and slowly heat it up until the glue fails.Problem is that I highly doubt the Lazy Susan is meant to tolerate this and that it will crack.There is also the bearing and possible grease to consider as I have no clue yet whether or not I can take the disks apart to get to the bearing.Is there any good idea or tip that I missed that I can try before risking to heat it up?In case you wonder: The disk is about 5mm out of center...

Reduce steel tube diameter by 0.3mm Answered

I am trying to make a DIY CNC machine, using linear rails and the expert advice in the many awesome instructables out there on this topic.  I hit my first roadblock, and I need some help/advice please... The 16mm steel tubes I ordered for the sliding rails wouldn't fit in the 16mm linear slide bearings SCS16LUU that I ordered, they are ever so slightly too big. With a lot of force I could get the rail in the bearing, but it wouldn't slide without extreme force - certainly not the smooth sliding motion it's supposed to be! I've probably ruined the bearings by forcing it in, but I'm not worried about that so much right now (I have spare bearings). I broke out the digital callipers, and the rail diameter measured 16.3mm - that's .3mm more than expected, and more than can fit in the 16.0mm bearings. So now I need to reduce the steel rails by 0.3mm. I have only hand tools at my disposal, and no experience accurately reducing steel rod diameter. I guess another alternative is increasing the slide bearing diameter, but these are sealed bearing units and difficult to get at. Does anyone have any ideas ?  Would it be easier to order new steel? Please let me know any thoughts on this, I'm desperate here.  Thanks in advance,
