- Q: are Tensor Oust Moc 7 Bearings, Abec 9 Tolerance good skateboarding bearings?
- Never used the Tensor bearings, or Destructo ones either. For the same money, you can get Pig Swiss. I use them in all my setups and have had very good luck. Bones Swiss are a little less money and almost as good as the Pig. If you want to save even more money and have very good quality, go with Bones Reds. They are a very good bearing for the money.
- Q: Are they connected with the main bearings? Are the trust bearings only on the outer portions of the crankshaft?
- My 4-cylinder has a total of four thrust bearing parts. They set next to one of the main bearings. There are two upper and two lower pieces so it takes a total of four. Yes they can be a problem as the two lower ones have a tendency to slip out of place and fall into the oil pan as they near the end of their useful life. But most 4-cylinders have a single thrust bearing built into one of the main bearings so they are not separate parts.
- Q: What material used in bearings? Describe the composition of elements.?
- Sn % Sb % Cu % PbApplications 933.53.5-Light and medium IC engine big end bearings 8610.53.5-Light and medium IC engine main bearings 80113.06General purpose heavy bearings (lead increases plasticity) 601028.51.5Heavy duty marine engine bearings, electrical machines 40101.548.5Low cost, general purpose, medium duty bearings
- Q: I have 8 bearings like any other skateboard. all 8 are crappy because my bro takes it out in the rain. Damn. And one of the 8 is all smashed up(long story). So im riding to school and when at fast speed it starts to wobble ALOT even on flat smooth ground. Would buying new red bone bearings fix this?thanks
- Buying any new bearigns would fix this. Bones are the best brand and I recomend them always just because I've used them forever and they work better than any other brand i've used. There is no fixing the smashed one up you could fix it from being wet by taking them out and cleaning them and then relubing them. I lube my bearings at least once a week more if I skate everyday. Don't ever use wd-40 on bearings it leaves behind a residue that collect dust and dirt making your bearings even more crappy. If you buy some beaings get some lube for them also. Bones red and some lube would cost about $25 total at a skateshop and the lube will last years. If not then buy lube later bones bearings are about $15-20 online and at skateshops.
- Q: i have bearing that i want to use for my skates and i don't know if they will fit
- Yup, you sure can.
- Q: if someone has the LUCKY ABEC 7 bearings.....the black part/side of it and the silver side of it....which one goes outward? does it matter? if it does... please tell me how because i dont want to screw up my board. THE ONE FROM ZUMIEZ... with the green/silver/black tin
- if they look the same it wont, im pretty sure its silver side out. but to put them in just place them in the wheel, put the spacer, and squeeze. simple as that. =)
- Q: This is a technical question depending small losses for example in clean room applications (every particle matters...)
- I assume you have tried shielded bearings, where the grease is contained inside covers that prevent its loss? Or possibly you do not have the funds to replace the bearings? Etc. I do not know the size of your pump/motor or whatever the bearing is on. I will tell you I have seen in an industrial setting on what I would call a small pump, they actually put a bag around the bearing housing to catch grease. Of course, the shaft ended at the housing so the bag did not have to come in contact with the rotating assembly. You could probably get more useful answers if you re-ask your question describing the size and physical configuration of the bearings and their housing.
- 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.

- Q: and what are they used for?
- honestly i dont remember all to well, i had a boyfriend in hs that skated and he would take me to skate with him and i havent gotten on a board for years, lol. or go to ur local skate shop. :)
- 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.
