- Q:Im paying $1,200 to replace rear differential bearings for a ?
- AS usual there is far more to this on the surface than might be as the differential bearings means this is to do with wear of the crown and pinion gears and the loading of the bearings this is a specialized job. it requires special knowledge and whilst doing this other bearings with in the differential need to be replaced hence the high cost so yes sometimes when the car is a newer model this is a cheaper option. but in cars of a certain age this repair is the only option so is the car really worth this expenditure.
- Q:Which one is the better of the two? im looking mostly for speed and for them to be waterproof
- I beleive they are the comparable bearing. Bones website calls the comparable bearing Swiss ceramic and Swiss ceramic labyrinth. Si, i could circulate with those that are the low-priced. in spite of the shown fact that, ceramic bearings are actually not cautioned for highway skating. The ceramic balls can not face up to the extreme results of touchdown from super heights. they are basically used for longboards the place speeds can attain in far greater advantageous than 50mph. in case you will concern your bearings to extreme landings, then decide for the labyrinth if used in a dusty or grimy ecosystem, and the standard Swiss if used indoors, or the place there is little dirt.
- Q:Okay so I'm buying 2 80mm/78a rink rat wheels and 2 72mm/78a wheels. But I need to buy some new good bearings that can go fast but arent to expensive. Please leave me a link or tell me what to type in the search bar to find them thanks.
- Pleasure okorder
- Q:like anything around the house or cheap
- graphite okorder )
- Q:same with the rods? '98 eclipse with a 420a engine, manual.
- Really you need to take the head off also.It would be hard getting at the piston end bearing by just dropping the sump.
- Q:ive been skateboardoing for about 1 year and my wheels are kinds slow so i would be pleased if you teach me how to clean bearings ty!
- yep, okorder /
- Q:What bearings should a beginner have on their skateboard?
- the free ones unless your looking for speed i remember my first skateboard, i had some bones reds and they were too fast so i tightened them up to make them slower lol and now their the worst ever. but if you want some good ones then you need to know how to clean them and take them off your wheels first.
- Q:well i thought my skateboard was lame but i figured out yesterday i had to loosen something,but the thing is, i don't know what, the bearing or trucks and what's the use for loosening or tighting each onep.s. what are some good skateboards for cheap and where can i buy themthanks in advance
- deffinatly okorder
- Q:I don't even know if the bearings are broken. The wheel is not spinning well and it feels like the bearings could be broken. How do i check if the bearings are broken? If they are broken, then how do i fix them or do i have to get new ones? If i do need to get new ones, then how do i know which ones to get? Or, do i just need to get a new hub? Which one would be the easiest. new hub, or try to fix/replace the bearings. By the way the bike is a BMX bike. specifically a Fit Tech 1. Thanks!
- It depends on what is actually wrong, and how bad it is. If there is a clicking sound coming from the hub as you spin the wheel, it could be a broken bearing. The clicking is caused by the remaining ball bearings rolling over parts of the broken one. Most cycles have cup and cone wheel bearings, but some later top end ones could have a cartridge bearing. If one or more of the ball bearings has broken, and the wheel hasn't been used much since it broke, then a new set of bearings could be fitted. The hub will need to be stripped, cleaned, checked for wear, and if there is no damage, re - built with the new bearings. If the wheel has been used for some time with a broken bearing, then the bearing surfaces in the hub may damaged, and it will probably be cheaper to replace the wheel, rather than fit a new hub. If in doubt, take the wheel to a reputable cycle store, and ask them to look at it, they should be able to advise you on the best solution.
- Q:All bearings are designed with tolerances to allow the moving parts to move, but how are wear limits determined? In other words, after time, the components will start to wear out and the bearing will become looser. Looking at some aircraft maintencance manuals, they provide wear limits in the radial and axial directions. But how are these wear limitis determined? Is there a particular calculation that is done or is an arbitruary number chosen?
- General ideas only. In the case of journal bearings with forced lubrication (oil pressure), increasing clearance results in oil pressure drop. Ideally, journal bearings hold an oil film which supports the rotating shaft and minimizes metal/metal contact. Automobile engines run for hundreds of thousands of miles using this strategy. Radial ball bearings will tolerate excess clearance (depending on the load) but the shafts they support often will not. In cases where oil seals are used, excess shaft play damages seals and permits leaking. In the case of motor or pump shafts, bearing slack permits rotor/stator contact or impeller/involute contact. Rotating masses are never perfectly balanced or axially aligned. Bearing slack multiplies unbalanced force and consequent load.
