- Q: I'am reading a book written in the 20's and he mentions reciprocal bearings but google hardly recognizes the term. But after some hard-earned googling I think we refer to them today as internal shaft bearings. The way he describes them is: reciprocal bearings are used for reciprocating pumps, and similarly used in on the connection rods of large internal-combustion engines, and in many mechanisms operated by cams. Thanks.
- internal shaft bearing = internal shaft bearing JUST EXACTLY WHAT YOU WERE SAYING IN YOUR QUESTION !!!

- Q: What skate bearings are better? ABEC 9 ABEC 7, ABEC 5, OR ABEC 3? I DON'T UNDERSTAND WHAT THIS MEANS
- ABEC is almost meaningless for skates or boards. It is an industrial standard for VIBRATION (not speed) in bearings on high speed machines that run at speeds that would be over 200 mph on a board. It became important because the previous ones that were used (20 years ago) were a grade called precision which are really sloppy. You can actually see them move them if you twist the center to the side. ABEC bearings were a huge move up and came without the heavy grease the was needed to make the precision bearings not rattle like maracas. However, now that a number was involved, the marketing people get into the idea that they can advertise higher numbers because people assume that higher is better. Almost all the difference in how fast a bearing rolls is in what lubricant is used.
- Q: How do I work out this bearings problem?A helicopter flies 15km on a bearing of 053, then 7km on a bearing of 112. How far north is the helicopter from its starting position?
- This problem needs some thought since when you use directions North and bearing 0 degrees is at the top of the page But, in math, if you use degrees, 0 is usually to the right. To translate, so your calculator will give the correct answer, subtract the bearings from 90 degrees. So 90 degrees minus 53 degrees equals 37 degrees. The distance to the east is equal to cosine of 37 degrees times 15km = 12 km Sine of 37 degrees times 15km equals 9km So the first leg he ended up 12 km east and 9 km north of original position. Then to translate the 112 degrees, subtract it from 90 to get -22 degrees Cosine of -22 times 7km equals 6.5 km and Sin -22 times 7km equals -2.6km. The second leg took him 6.5km farther east and 2.6km south since the 2.6 was negative, it is in the direction south. Next, add the two together Cos + Cos for the travel east and you get 12 + 6.5 so he ended up 18.5km east of the starting point Add the Sines for the north/south directions. 9 -2.6=6.4 km north of starting position.
- Q: I know it all depends on preference, but is it worth upgrading from ABEC 5s to ABEC 7s?

- Q: I need at least a link because i got really good bearings
- You don't need to ask the same question in three areas, two of which aren't appropriate. Are you asking how to take the bearings out of the wheel to replace them or how to open them up to clean or oil them? Unlike a couple of people have said, inline skate bearings are NOT sealed. Sealed bearings have way too much drag for inline skate or skateboard use. The method of removing from the wheel that one of them posted is just as wrong. Please clarify your question. If you want to remove them from the wheel, are the axles 6mm (1/4) or 8mm (5/16)? If you want to open them up, do the shields have a rubbery surface or metal surface? If they have a metal surface, are there a row of visible notches around the outside of the shield? Then I can tell you what you need.
- Q: I currently own a 2009 Lightning Long SS, it has just a bit over 5000 miles on it. I was riding it down the freeway the other day and the rear end started to wag around and progressively get worse. When I got it to the shop I looked at the rear wheel and the bearings on the right side where the belt is were ground up and gone, just metal shavings. So my question is, should/could that have happened on its own without anyone screwing with my bike or a mechanic messing something up when I got my tires changed or during the regular maintenance? My riding habits are normal, I have never laid it down and it has been in for all its regular maintenance.ThanksScott
