Q:and what bearings do you have? how long have you had them? have you done anything special to speed them up in any way to make them even faster then when you bought them (besides breaking in)?

Pig Swiss or Black Panther Swiss Spinning an unloaded wheel doesn't really tell much except if thed bearing is dirty or has failed. A larger wheel will spin for a longer period of time. Thicker lubricants will cause an unloaded bearing to spin for a shorter time, but won't be effected under loads. The only proper test is to use different bearings under identical settings. Have a rider ride down a ramp and see how far he/she goes. Unless you race longboards, skate pools or other transition skating, the need for a high speed bearing is diminished. The average street skate performs tricks around 2-3mph. Transition skaters can reach 30mph and longboards can exceed 50mph.

Q:how do i change my swingarm bearings on my 2004 rm 125?

Use okorder /.. Swingarm needle bearings are very easy to damage.

Q:We have a 1990 Plymouth Voyager and we need to put on new wheel bearings (well my husband says the whole hub)..does anyone know how to go about this?

heres what you do the 1st step: Get a screwdriver and hammer Step 2: positioned the screwdriver interior the process the bearing and wheel Step 3: positioned yet another wheel below the single you like the bearing is going in Step 4: Pound the real of the screwdriver with the hammer till the bearing is going each of ways in Step 5: Lather, rinse, repeat if nessecary

Q:So when the wheels don't turn too well its the bearing that need the cleaning right?If possible instructions on how to clean bearings would be nice.

Oooo guy, cleansing bearings is a tricky interest. ok 1st, dont pour a answer/water/something liquid on them. it can cause them to rust up and that wouldnt be relaxing. in case you pick to bathe the exterior of them whilst their nevertheless interior the wheel, what i do is take a toothpick and in basic terms scrape off the airborne dirt and dirt and grim. it works surprisingly darn nicely.

Q:what kind of bearings do i need for a1976 honda cb750?

Phillip missed it on several points. The crankshaft main bearings and con rod big ends are replaceable plain bearings, small end rod are non-replacable plain with full floating wrist pin, camshaft plain, tranny shafts are caged ball bearings, steering head are loose balls (really cheap crap), swing arm pivot are plastic bushings (really, really cheap crap) and the wheel bearings are caged balls. You should be able to replace the steering head and swing arm with tapered roller bearings, which will really improve handling.

Q:how long does crankshaft bearings take to replace on snowmobile?

After splitting the engine case the crankshaft must be pressed apart in sections to remove the roller main bearings and needle bearings on the big ends of the rods. This is not a job for an inexperienced person with the wrong tools. All the sections of the crank must be indexed properly in a fixture before they're pressed back together. Nowadays a *new high performance snowmobile crankshaft including the bearings and rods cost more than a crankshaft for your car!

Q:What are some fast skateboard bearings bearings?

If you can spend a lot of money, bones swiss ceramics are the best bearings out there, but run around $120-160. Any bearings that cost around $20 or more are fast, but brand-wise the highest quality are bones. By standards, bones reds are the highest quality for the price. Almost every skater uses bones reds. They cost $20 and are better than flip, panther, and other bearings at the same price. They are quite a lot faster, and a lot more durable as well.

Q:What is the reason the inner ring of some roller bearings are tapered, while others are flat-bored. What are some of the typical applications for roller bearings that are tapered on the inner ring?

tapered roller bearings not only can support a radial load, but they can also resist an axial load. This makes them useful on helical gearshafts because helical gears give axial loads. You can find these in transmissions, many types of gearboxes, many places that have rotating shafts which may require that the shaft be subjected to axial loads.

Q:thanks for your help

If okorder /... If you're talking about dismantling the actual bearing... Take off the shield with a needle or something, hit bearing multiple times until it breaks. Gather pieces.

Q:I recently purchased some hockey quad boots, but the bearings are slow so im looking to swap them with some abec 9s or red bones, but the axels on the skates are 7mm. Im used to 8mm axels and fast speed bearings, which are easy to find at that size. Are skateboard bearings suitable for quad skates with 7mm axels?

You would need spacers to make the bearings fit snug over the axles. If no one makes them, you could try some of the brass tubing that you can find in hobby shops. ABEC is meaningless for speed. It relates to how much the bearings can wobble in high speed machinery. If your bearings are really slow, they probably have a grease or heavy gel as a lubricant. Try cleaning out the lubricant and putting in a little oil.
