- Q:i have bones reds bearings and i dont know if there abec 5 or abec 7 tell me what you think?
- bones makes many types of bearings. Some are ABEC rated and the better ones are not. The ABEC rating is for vibration in high speed machines that run at speeds similar to skating over 200 mph. They are not the best design for skating but companies make a lot of them for other reasons and it is cheaper to get them than a design that is custom made. Bones, Twin Cam, Zero Drag, and some other companies have custom designs for their better bearings.
- Q:How many times have you had your front bearings go bad on your Alero, what approximate milage? I'm at 87k and am ready for my third set!
- what conditons are your vechicle put through every day,pot holes,bumpy roads all factor in to the life of your bearings,the next question is what brand of bearing are you using,Factory bearings tend to last longer,There has been alot of time and money spent to engineer these vechicles from GM.Hope i helped.
- Q:I'm getting a new board soon.I'm thinking about a zero deck with independant trucks bones stf wheels and bones super swiss six bearings.
- zero deck with venture superlite trucks ricta wheels reds precision skate bearings shake junt hardware black magic griptape
- Q:OK, so our ball bearings on our 2003 Hyundai tib went out pretty bad!! We bought new ones from auto zone and replaced them, within a week the bearings were destroyed again, so we brought our car to the base auto shop. The told us the bearings we bought were bad. They replaced them and we just spent $405 for them to replace them, put a new tire on and to do an alignment. We picked up the car monday! It is now only Thursday, 3 days later and the car seems to be making a grinding sound like it was before the 1st time the bearings went out. What are the odds we got 2 bad bearings? We do know that eventually the axle needs to be replaced but 2 mechanics have told us that it will be months before it NEEDS to be done! I just don't understand. The car is in fair condition and worth around 3,9500 as a trade in. We will prob. just trade it in soon bc it's not worth it. Has anyone else had this problem!??
- there are things to consider here. like are you getting them in straight and if they are tapered bearings they have to be packed before installing them and if they are adjustable maybe your adjusting them too tight.
- Q:Why do so many large railroads (ie,class I) flat out refuse to let rolling stock that has friction bearings, from operating or (at the very least) being moved across their system(s), even if the equipment is maintained in a better condition than roller bearing items of the same type/vintage?I appreciate all insight, -- Thanks in advance!
- Friction bearings are not illegal, but banned for interchange per AAR interchange rules. So the car owner can't force the railroad to take the car. Railroads could accept the car at their discretion, but lately the class I's have been very risk-averse. Probably because their railroads are darn busy. I have heard of a few interesting hospital moves of large blocks of heritage equipment including Shays on their own wheels. However this was done by someone very influential with the Class I involved, and at the least busy times (i.e. Christmas day).
- Q:I heard using mineral spirits is a good way to clean bearings, but I also heard some can end up damaging them
- Usually we do not clean them you simply pack new grease into them forcing the old crap out
- Q:nd which is betr bones reds bearings or minilogo bearings?
- FKD bearings seem to last longer and can endure flip tricks and such, but black panthers roll a little faster. I think it's all down to opinion though, it all depends what you personally prefer.
- Q:i want something thatl go fast
- I'll cover some basics with you about advanced longboarding. I'll first start by talking about trucks and bushings, then I'll move on to bearings. Longboarding can be divided into two sub-categories, that is downhill riding and free riding. Now each type of riding has different sets of parts which differ from each other to provide maximum performance for the style of riding. Downhill boards are usually at top performance with trucks that have a 42 degree base plate. You will sacrifice the maneuverability and carving ability of trucks with 50 degree base plates to sturdiness if you get 42's. However, you will be able to handle speed much better on 42's and the risk of 'speed-wobbles' will go down. Bushings are pretty difficult to choose. With all different hardnesses and shapes, it's hard to recommend anything that you will be satisfied with. Bearings are simple. Any bearings are basically the same but MAKE SURE you get completely sealed bearings. Ceramic bearings are pricey but supposedly improve performance. I recommend you look into Randall or Paris for trucks (180mm standard), Khiro for bushings (unnecessary), and Bones for bearings.
- Q:i was thinking about getting some pig wheels and either some black panthers, or some bones reds wat kind do u think i should get?
- Bones Swiss Ceramics are the best you will find. But it shouldn't really matter too much what bearings you get unless you get REALLY cheap crappy ones, then you may notice a difference.
- Q:Any suggestions? Been lookin around.. found arsenal abec 9s reeeeallly cheep but i cant find them anywhere to see how bad they are if i can get 16 for $10. Secondly my skates are about 4 years old should i get new spacers as well?
- $10 isn't bad for a set of bearings, especially ABEC-9's. However, bearings are overrated. Unless you are a pro, and can utilize any gains you get from top of the line bearings, you can get away with any old style of bearing. I get mine from my neighbor. He is a supplier of industrial bearings. I get them form him for about 25 cents each. I have gotten a bunch for my friends as well. They all say to a man they can't tell the difference. Spacers shouldn't wear out, so unless you have another set of wheels, you shouldn't need more that 8 spacers. I get second and third sets to make wheel changes easier. I play on wood, concrete, and sport court, and can't afford three pairs of skates, so I change wheels for each surface. Have a good one! Steve.
