- Q: what is the difference between alloy bearings and plastic bearings?
- Alloy bearings are med out of metal alloys. Plastic bearings are made out of plastic. The metal ones are more durable and last longer, but are heavier than the plastic ones.
- Q: After a wheel alignment my wheel bearings went bad, immediately.
- Not greased. If they are bad you will know when you see them. If they are on your rig fell the hub and if it is hot they are bad.
- Q: i saw some that said speed demons, abec 7 and some that just said ABEC 7 which ones are faster?
- Long board wheels are larger and wider than skateboard wheels. And because of it, longboards are faster for travelling compared to skateboards and it can even roll to rougher terrain. i haven't tried to put longboard wheels on my skateboard so i guess you had to try to put the longboard wheels on your skateboard and see if the wheels won't touch the board when you ride it. Else, you had to replace your skateboard wheels or use your longboard.
- Q: I have a 100 dollar budget on either trucks bearings or wheels. I have been riding my long board for a while but I dont really know to much on how most of the parts work. I want my longboard to go faster and stay fast for a while without slowing down. Should I buy new bearings or trucks. I have a sector 9 bob marley pintail longboard with bone reds trucks. If I buy knew bearings or trucks do I have to buy new wheels as well. But If I had to pick either buying new bearings or new trucks which one would be best for my longboard. thanks
- If you have $100 you can seriously buy both. But if you are looking for longer roll time, bearings are what you need. NEVER SPEND A LOT OF BEARINGS!!! Bearings should never cost more than $15. If you get a good set of bearings and keep them cleaned and lubed when needed, there will be no difference between $100 bearings and $10 bearings. I recommend MileHighSkate or Magic bearings if you can get them. They are high quality and $9. If not, Bone Reds are easy to find, but arent as nice and cost $15. I also HIGHLY recommend you get bearing spacers. They are $5 and go inside your bearings and allow you to tighten your wheels all the way, giving you a smoother ride. You should also have speed rings too (those 8 rings that come with your current trucks). Trucks will not help you go faster.

- Q: I need new bearings, a freewheel remover, and a cone wrench, I'm not sure what size on the cone wrench I guess 15 mm
- 1/4 cone 15mm rear 13 mm front or 16 and 14 you can get one wrench that does all 4 sizes yes true 13 14 15 16 one wrench to rule them all but then you need a pair ha grow one wle
- Q: My buddy bearing popped out. I think grease got all over the wheel. How do I clean the wheel and repack the beaing with grease once I put on the new buddy bearing.
- Just use old rags to wipe off the old grease. Then reinstall the bearing buddy and put the new grease in by pumping it into the bearing buddy. Don't disassemble the hub bearings unless they have failed and you are going to replace them. If that's the case, prepack them before installing. Check instructions from your parts supplier......I learned to do it by hand from a mechanic 45 years ago. Good Luck!
- Q: Anyone know the range at what I'm looking at for completely full ceramic bearings for a longboard?
- Assuming you are looking for not only ceramic balls, but inner and outer races as well. These bearings will run around $240 a set. Most bearings that called ceramic only use ceramic balls, but the races are still steel. Some cheaper 'ceramic' bearings only use a ceramic coating on the balls. You might want to think about stainless steel bearings. They are very resistant to corrosion and cost much less than full ceramic bearings, and only a little more than regular steel. SS Bearings with ceramic balls cost about double that of all SS bearings.
- 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.
