    Oiling a Thai gate.

    First you have to understand that I have one of them rolling Thai driveway gates. You know the kind, the one where you want to keep the dog in and the other dogs out.

    Well every now and then the gates are sorta hard to open. This what I use the old standby WD-40.


    My neighbor (who I never see working) says that in Thailand the sprays are wrong. This is what he says is the stuff.


    This product can be bought at HomePro.

    Seems to work on his gate.


    Will have to wait and see how it works on my gate.

    Your neighbor is so right, the gate wheels has roller bearings and they need to be greased every now and then.
    Mine seems to need it more now than then.

    The spray will actually remove grease..
    It is good for removing rust though (maybe once yearly) but you have to apply grease afterwards.
    The voices in my head are mostly kind, I also like the music.

    The rollers they use are shite and corrode away to nothing in a year or so. Where can you get decent quality steel rollers?

    I agree, but it's not the wheels corroding, it's the bearings. For me at least..
    Chineese shite, but what to expect of a roller bearing which together with the wheel costs less than 100 baht ?

    I have bought Teflon wheels with proper bearings, they are said to last for 10 years, and they are around 500 baht.
    Still waiting to put them on, I have not been able to get proper bolts with the same size as the hole in the bearing.

    But smearing that peanut butter looking shit on the outside will not grease the bearings, they should have a zerk fitting in the end of the axle shaft or take em off and pack the cavity and bearings with grease em and put em back on.

    Thai will not grease any bearings, a friend repairs bicycles and he puts in new bearings in the fork neck, wheels and crank hangers, puts on a thin film of grease, if any, and put em back in, never any actually in the bearing or cavity, shit they be gone in a week.

    That's what I do when I replace my wheels, hoping that a lot of grease will keep the water away.
    I don't waste expensive roller bearing grease on them cheap bearings.
    Bought a jar of Castrol grease in the motocy shop , the same grease that I use on my motocy chain after washing it.

    Look at the roller and bearing, both cheap rubbish and look where they have to work. At ground level with rain water flowing over it and sand and dust every time your slaves sweep your driveways. You can't expect much and there isn't much you can do. greasing them just attracts more dirt. Loms got the right idea with teflon rollers and sealed quality bearings. I would be interested in seeing how that lasts.

    I don't think I would use that shit on my chain, I now have got some suppliers to get the regular chain spray lube that comes out thin and thickens in the air and it will get into the rollers on the chain and do a lot better job of lubing and staying on the chain.
    Also works to spray down in the housings and lube the throttle, clutch and speedo drive cables.
    Here it is called Kettenspray on the cans.
    Fact you might get some of that and spray into the bearings on your gate..

    Is that stuff a sort of copper colour?
    If so it is graphite grease and is very good for using in high temperatures, I used to use it in sealed bearings (pop off the seals and pack it full of the grwase)
    I think using it on a gate in thailand would be effective but slightly overkill.
    I would pack the bearing and use a teflon, silicone or PTFE lubricant on the runners mainly just to keep rust away.

    Homepro have a white grease that comes in a can, the solvent propellant evaporates leaving a film of very adhesive grease behind which is water and temperature resistant

    No, it's white-greenish.
    I know of the graphite grease but don't think it would do much better
    since the whole gate wheel construction has major flaws:

    A ball bearing is not designed for taking up force !
    A heavy steel gate will put all of it's weight on the bearing axises which in my case, and all other gates I've seen, is a normal bolt.
    The lower side of this bolt will transfer all the load into the bearing.. Stupid !
    My bolts even have a smaller diameter than the bearing so no chance for part of the force being taken up sideways. That's even more stupid !

    The bolt is threaded all the way, not only in the top.
    So the bearings rests on threads

    Finally, the metal pieces (on both sides of the bearing) making up the wheel assembly does not tighten to the bearings. So no "seal" to prevent sand and water getting inside.

    It's a typical example of Thai engineering , no thinking of tomorrow.
    Works today, fine..

    Still waiting to put them on, I have not been able to get proper bolts with the same size as the hole in the bearing.

    I just face this problem ! Went to the shop and the roll inclusiv bearings cost 100 Thb !

    I tried running it by hand and it locks and crotches and cratches, most prolly also only 4 balls inside in place of the 7 or 8 necessary...

    So i'll buy the rollers for a 100 Thb, throw the chinese bearing out and will fit proper SKF or another reknowned brand like FAG.... in replacement.

    The branded bearing must be choosen with plastic closing aside to avoid dirt going in and also that you do not need to grease it every month or so... 6302 RS for my need...

    1 Bearing is 75 Thb, there are 2 pcs in each roller, so it will be a 1k for the repair...

    the old rollers cannot be used, the seat for the bearing increased, problems would quickly come back if not exchanged...



    Anybody needs my brand new chinese bearings ? for free just pick it up...

    ^ Buy roller bearings instead of ball bearings.
    You can not expect a couple of balls to carry the load of a gate, the balls will get deformed and the bearing will lock.

    Single Row Taper Roller Bearings must be right choice.

    Great product called Super Lube in the spray on form will work wonders. I use on gate and motorcycle chain. It contains PTFE particles that not only lubricate but will not attract dust and dirt.

    Roller bearings with plastic seals will work, but taper [timken] bearings will not work the way the gate roller assemblys are made, a taper bearing has to be pre-loaded and there is no way to do that.
    But the ball or roller bearings will work as long as the outer race has a tight fit in the wheel and there is a way to lock the inner race to the mounting so it will not turn, with slim spacers or something.

    Unless one race is locked on the axel and the other turns with the wheel there is no need to have bearings.
