Why do you need to grease sealed bearings???

That depends on the purpose of the bearing and the environment you live in. I live down in the South where it is damp and the humidity is always lurking around. Therefore, you might want to have a grease fitting for your sealed bearings. If you are using these bearings on spindles on a lawn mower cutting deck I would definitely put grease fittings on the spindles and grease them often. Always blow your deck off with a blower, never wash your deck! Sealed bearings can be greased. On mower deck spindles with zirk fittings the seal is removed on the inside that face each other and the outside seal stays in place, therefore the grease can flow to all parts of the bearing.

Sealed bearings are just that....SEALED! They are greased when assembled and have "shields" on both sides to retain the grease throughout the useful life of the bearing. The shields consist of various materials relating to the intended use and longevity of the application. There are however some sealed bearing applications that do require r e g u l a r greasing. I have seen them mostly in farming equipment and they are identified by a small hole in the outer race. I have replaced thousands of bearings, and generally speaking, I will always upgrade to a premium sealed bearing if it is available, and if the cost and application warrant it.

If it is sealed on both sides you can't grease it. Open on one side you can grease it.

sealed bearings are just that, sealed, they can not be greased, and the seal keeps the grease in and imperfections out, when you think they make a noise, replacement is in order, good luck, Dick

You cannot grease SEALED bearings. You grease bearings to keep them lubricated. But if they are sealed you cannot grease them.

It is covered in machine oil but you need to provide your own grease/anti-seize compound for installation.

Should not have to add grease to the sealed portion of the housing for many thousands of miles but be sure the exposed needle bearings in the back side of the hub have plenty of grease packed between the needles. The only way grease can be added to the sealed portion of the hub is to remove the ABS sensor and pump grease into the opening. This can be done later when it comes time to repack the needle bearings. My original hubs had 172,000 miles without ever having grease added and were not noisy or loose. I completely disassembled them after removal and there was still a small amount of grease inside. Only 1 showed any sign of wear or heat build up.

Yes they do have sealed bearings, this pedal is strong I am using everyday on my MTB and they rock!

Just use the same grease as you would on your wheel bearings just use it sparingly. I love this system it just takes seconds to level my pop up.

Hi Mike, Great Question - I checked. The grease nipple is inserted into the top of the shaft and hole for the grease extends past the top bearing and is cross drilled below the top bearing. The grease fills the cavity between the upper and lower bearing. The lower bearing has no seal on the top side thus it would be lubricated and the grease would also help to keep the water and dirt out. The top bearing has seals top and bottom. I hope this helps.

I just winged it. I also used so bearing grease. It took me 3 hours and it hardly got used.

I am not sure that the bearings are sealed. I have not looked at mine to see if they are sealed. The seals on the inside of the bearings should be removed, this will allow the grease from the zerk to get into the bearing. Hope this help.Joe Storey

I used a good, high quality wheel bearing grease. By the way, they're working well! I hope that helps Kevin!

That's a good. ? Lol. I'm a tech of 10 + years and I never greased. I just push the ball of the fitting down and pour a few drops of lite oil in it.

It's mostly the outer bearing. I don't think it can easily push the grease all the way to the inner bearings, although I never had an issue with the inner bearings. If your inner bearing gasket isn't leaking it shouldn't be an issue anyway. As long as you re-pack your bearings once in awhile you will be fine if everything is installed correctly. These definitely help though, especially if you were to have a seal go out, it could keep it greased for awhile.

Good Morning Paulette, I have have not had the need to do this yet with my bike. But I can give you a word of advice that I have learned from other pieces of exercise equipment. Use a dry lubricant as the wet tends to hold dust which will build up in time. The dry lubricants. like used on outdoor bicycles, does not accumulate dust. Sorry I can't give you a procedure. I just haven't had the need to open it up yet.

my best assumption -from experience , is to always use the lubricant thats called for . when i used an oil other than what was called for on a seal , it ruined the seals . also remember to use the required oil sparingly ( follow the recommended anount and frequency)

It takes what is called a pin grease gun. Part # for the grease kit which includes grease gun,oil and grease is 105-LBK1. The 105 is just the grease that IR sells. They recommend to oil it every time it is put away and to grease it every 48 hours of use or 2 times a year. Moisture from the compressed air will cause damage if it is put away wet. Grease gun is needed because the grease has to be forced from the grease fitting to the chuck.

I'm not sure about the bearings but if I had to guess I would say Yes they are sealed. No squeaks ever, I've had the chair for 15 months. Let me tell you though, it's not that comfortable and it takes up a lot of room.

I have done that to another grease gun before. You would probably have to improve the seal on the plunger so that the oil wouldn't leak out. Hopefully no one ever pumped grease into those fittings on your machine.

It comes full sealed with all bearings and grease fitting ready to put on. I highly recommend that you grease it more upon replacement because they never put enough grease in from factory and it will wear out fast if you do not add your own grease to it. I have replaced two of these it is simple and well worth the time and money.
