Q:what is the difference between sealed & unsealed bearings?
sealed bearings are encased and unsealed are caged or loose ball bearings. if you can see the actual ballbearings they arent seal. if they are enclosed they are sealed.
Q:tandem axel trailor bearings?
If the heat was caused by the bearings, they should be slightly discolored. On my tandem axle car hauler, I installed grease caps with zerk fittings on them. Before each long trip, I get out the grease gun and give each about 15 pumps. Since yours gets exposed to water, I would pull all and repack, looking for signs of corrosion, pitting or rust, and discoloration. Replace as necessary with new seals. Get the greasable caps.
Q:How do Bones Reds Skate Bearings compare to the ABEC Rating?
ABEC is a label.. and if you look into it the ABEC rating system you will see it is intended for industrial bearings for things such as machines in factories.. when your building something like a dumptruck or a machin that creates alluminum cans ABEC ratings matter because u dont want to have to change ur bearings for sumthing so complex so the rating system works great.. but for skateboards ABEC really means nothing because if u have ABEC rated bearings with a rating of 3 or 7 it doesnt matter because if you ollie a 8 set the shock from landing on the bearing is exactly the same. so wether u pay 30$ or 20$ for the 7 or 3 rated ABEC bearings theyr both going to break in the same amount of time. go with REDS becuase reds are cheap and theyr made by the best bearing company on the market (for skateboards)./// cheap is good
Q:When u need wheel bearings will your tire come off?
Yes it can. Steve is completely wrong. I had this happen to me today. I started noticing smoke coming from the wheel bearing and then it started getting loud and it felt like something was breaking off in the wheel area. The abs light came on and I drove it around the block and then the wheel just popped off. It was crazy. Never thought I'd have something like that happen to me. I was lucky that I wasn't going fast when it happened.
Q:1996 camaro bad rod bearings can i do the work myself?
sure okorder.com/
Q:What would happen if I don't do something about my Wheel Ball Bearings?
The ball bearings in the races if the wheels are not serviceable. The entire wheel bearing hub assembly must be replaced. When front wheel drive wheel bearings start to go bad they'll roar like a freight train getting louder as you drive faster. If they are not repaired you will ruin a spindle or a CV joint if your wheel doesn't lock-up or crash into a wall first. NAPA sells SKF wheel bearing hub assemblies and Carquest has Timken. Don't shoot yourself in the foot by buying off-shore wheel bearings.
Q:Is replacing the main and rod bearings in a 1988 thunderbird worth doing and how intense is it?
because of the fact's a extra cutting-edge gm engine, i might guess that's a collapsed piston. the skirt of a collapsed piston will make a knocking sound because of the fact that is hitting the cylinder wall. if the noise is loudest while the engine is first began in spite of the undeniable fact that it each so often is going away, i may be almost particular that that's a piston.
Q:What are the needle roller bearings with an inner diameter of 14, an outer diameter of 20 and a width of 20?
I didn't find a modelIt should be non-standard
Q:Does the Abu Ambassadeur 5000-C have bearings inside the spool?(early 90's model)?
the only bearings on the 5000C are the ones at the ends of the spool shaft. one external, underneath the tension adjustment cap and the other inside the opposite sideplate, held in place by a small metal clip. *the only BALL bearings. other turning contact points have bushings which to a nit picker, are, in fact, bearings.
Q:Give a detailed procedure of maintenance of electric motor bearings and the effects of overgreasing?
Motor manufacturers have recommendations which are specific to the device and service category (ambient temperature, load, duty cycle, air quality, dust, particulates, etc.). These vary for journal, roller, and radial ball bearings. In the case of electric motor bearings; cleanliness and free air circulation for cooling are critical. Ball bearing are generally sealed or shielded, and permanently greased. In cases where they are being restored as they approach the end of design basis service life; they can be cleaned in an oil bath (not to exceed 100C), rinsed in solvent, and regreased to ¼-⅓ of the free volume. Excess grease is universally regarded as destructive. Over greasing is said by motor manufacturers to create overheating which boils off volatiles and changes the properties of the grease. The vapors from condensation deposit nearby trapping dust, blocking air flow, and exacerbating overheating. Lubricant manufacturers cite degradation of lubricant due to shear.
