Q:Questions about manual transmissions and bearings. Help?
Mainshaft bearings, countershaft bearings, input shaft bearing.....some are tapered, some are roller,some are needle bearings.........
Q:how to replace a 2000 audi a6 wheel bearings?
How many miles does your car have? If it's less than 100,000 it's odd that it would need bearings already.If it's the drive wheels, they are torqued on and you'll need to replace the bolt with the bearings. The new bearings usually come with the bearings. In the non-drive wheels, it's easier. If you don't have the proper tools, it may be best to take it to a garage.
Q:What tools are need to change wheel bearings?
Jack ,lug wrench alittle muscle caliber remover, bolts vary with different makes, pop caps off and remove cotter pin remove nut and pull rotor off, outer bearing will come out first and the inner is held in by a seal, you could just get new seals or be careful with the ones you have, pack new bearings with new bearing grease inner and outer, put bearing grease on spindle install inner and tap on new seal make sure you note which way you take off the inner seal. install rotor put nut on tighten nut tight and then back it off half turn. same to other side. Hint pick up a Haynes manual for your year car it will assit you start to finish.
Q:what brand of abec9 bearings should i get for my longboard.?
specific; in spite of the incontrovertible fact that, the ABEC score gadget has greater to do with the bearing's tolerance than the bearings velocity. save that for the time of concepts. the ABEC rated bearings are used for greater suitable than in basic terms skating; those bearings have been examined on a gadget.
Q:Which method should be used for axial fixing of needle roller bearing in stamping outer ring?
General stamping ring needle roller bearings are the outer diameter and the hole is fit to the location, so for stamping ring bearings have a pressing force of the technical requirements. Here I put it in the production process: stamping, heat treatment (about carburizing layer to control, otherwise the last edge will open - Cases) left - lips - cast oxide annealing oxidation layer, the holder on the needle sleeve ring, stamping edge (technical requirements: the rolling head edge within the height, diameter, (note that both ends and in the middle to be consistent) and pressed into the ring after the gage qualified).
Q:Which Skateboard Bearings Are Faster, Bones REDS or Rush Abec-7 bearings?
probably bones reds. bones has been making bearings almost as long as skateboarding has been around. and all that abec measurement stuff is all bull poop they are just measuring how long and how fast a bearing will spin for on some metal pole they aren't measuring it under pressure and the conditions of when your actually riding so go with the bones
Q:What is the best lubricant for a skateboard ball bearing, made for bearings or otherwise?
go to a skate shop and ask for lubricants and they will try and sale some regular lube but for my bearings i use bones lubricant. dont try and use grease lol that wont work. and if you buy pretty expensive bearings like ceramics or bones might as well get some good lubricant. dont over do it by spilling the entire bottle cuz ur gona get a lot of dirt in the bearings making it worse. another tip what ever you do dont use wd40 that will ruin ur bearings in no time. trust me iv dont it iv messed up some black panthers by using wd40, it makes them bust faster.
Q:what kind of bearings should i get for my skateboard?
Here is a link with a list of bearings out there. Also here is some info on selecting them. How to determine the correct size of bearings for your wheels. Bearings have different qualities and may not vary in size. The best bearings to shop for are the ones with a lot more sealing, has the inner ball-bearings with higher quality metals. Even though they can be costly, you are paying for the quality that’s worth the price. All skateboard bearings are the same size and will fit to any type of wheels.
Q:loose fits and bearings?
Bearings are matched to shafts and housings to a tolerance of .01mm (ideally). This fit permits creep to distribute wear over time, while providing uniform and stable support for the inner and outer races. Tighter (interference) fits are destructive. Loose fits, which permit chatter and impact, are equally destructive. If you are involved in maintenance you will get your money's worth from the attached link.
