11:50 AM goppo: hi
11:53 AM goppo: i have a swinging shaft and the shaft rotates on its own axis. does anyone know of a good way to stop shaft from moving axially other than using thrust bearings?
11:54 AM goppo: are nylon washers good?
11:54 AM Tom_L: possibly
11:55 AM goppo: i suppose another option would be circ clips, but they certainly have very high friction
11:55 AM Tom_L: depending on the loads, nylon would be fine
11:56 AM goppo: it's about 3kg. might be a bit much for nylon?
11:56 AM Tom_L: axial load?
11:57 AM goppo: yeah
11:57 AM Tom_L: bronze
11:57 AM goppo: are thrust washers simply nylon washers?
11:58 AM Tom_L: depends on the application
11:58 AM Tom_L: there are regular steel thrust bearings
11:58 AM Tom_L: steel, nylon, bronze etc thrust washers
11:58 AM goppo: right
11:58 AM Tom_L: what rpm?
11:59 AM Tom_L: alot of factors...
11:59 AM goppo: very slow. about 60rpm
11:59 AM Tom_L: swinging indicates low if any rpm
12:02 PM goppo: are nylon thrust washers same as nylon washers? or are they made of slightly different materials?
12:02 PM Tom_L: nylon is nylon
12:04 PM goppo: i remember reading that some mix metal into the nylon
12:04 PM Tom_L: very possible
12:05 PM Tom_L: probably bronze flakes
12:05 PM goppo: yeah, something like that
12:12 PM goppo: are nylon washers easily worn by friction?
12:46 PM weyland|yutani: they are not selflubricating if you want that you need something like Ultra-high-molecular-weight polyethylene for example
12:56 PM weyland|yutani: well nylon is self lubricating but not as wear resistant as those special polyethylene
