Q:The guy at the auto shop said my wheel bearings have 'play'?
It used to be common practice to remove wheel bearings and inspect and repack with grease and replace and re-torque. This has become a thing of the past with the newer bearings being replaced as a unit with the abs systems in use now days. If your wheel has noticeable play top to bottom it a safe bet the wheel bearings are worn past there useful life but ball joints or struts can also cause play. If the play is front to back, the steering components should also be checked to determine if it is the steering or bearings. And yes it can be serious and dangerous. Any problem with the steering or suspension and rotating parts should be addressed immediately.
Q:where can i buy furnace inducer motor bearings?
You can swap out the entire motor in ten minutes. Why would you want to replace the bearings? Just change the motor. Google is probably your best option. Most local part suppliers will not sell to the public, at least here anyway.
Q:Where can i get new ball bearings for an airsoft 40mm grenade.?

Q:what kind of bearings are better for a skateboard???
dont let price fool you, reds bearings work well for a pretty inexpensive price
Q:Rear bearings vs differential, '05 Sport Trac?
Sounds like outer wheel bearings but it could be the differential bearings as well. The only way to know is replace the wheel bearings and see if the noise stops. I'd check the gear oil level as well since if you were low on oil that would kill the bearings and the differential. If it's low make sure you add the specific kind for your axle.
Q:how are wear limits on bearings determined?
General ideas only. In the case of journal bearings with forced lubrication (oil pressure), increasing clearance results in oil pressure drop. Ideally, journal bearings hold an oil film which supports the rotating shaft and minimizes metal/metal contact. Automobile engines run for hundreds of thousands of miles using this strategy. Radial ball bearings will tolerate excess clearance (depending on the load) but the shafts they support often will not. In cases where oil seals are used, excess shaft play damages seals and permits leaking. In the case of motor or pump shafts, bearing slack permits rotor/stator contact or impeller/involute contact. Rotating masses are never perfectly balanced or axially aligned. Bearing slack multiplies unbalanced force and consequent load.
Q:change bearings or hub ?
It would be easier to take it to a machine shop and have them press out the old bearing and press in the new or to purchase or rent a hub shark so you can do it yourself (provided you have a compressor and impact).
Q:What brand of abec - 9 bearings should i get for my roller blades?
$10 isn't bad for a set of bearings, especially ABEC-9's. However, bearings are overrated. Unless you are a pro, and can utilize any gains you get from top of the line bearings, you can get away with any old style of bearing. I get mine from my neighbor. He is a supplier of industrial bearings. I get them form him for about 25 cents each. I have gotten a bunch for my friends as well. They all say to a man they can't tell the difference. Spacers shouldn't wear out, so unless you have another set of wheels, you shouldn't need more that 8 spacers. I get second and third sets to make wheel changes easier. I play on wood, concrete, and sport court, and can't afford three pairs of skates, so I change wheels for each surface. Have a good one! Steve.
Q:how to replace wheel bearings on a 92 toyota celica 2.2 GT?
Those bearings are pressed in you need to take the spindle to a machine shop and have the old ones pressed out and the new ones pressed in I have used my air chisle to get them out and my bench vise to install them but its a pain in the a$$ good luck
