Topic: Roller Thrust Bearing Problem
Hi All,
I finally got the new Filastruder and Filawinder working together great.
After about five hours of nice 1.75 mm filament I heard sort of a
bang sound. The pin sheared and it stopped extruding. Just the
motor shaft was turning inside the coupling. I took it all apart and
discovered the entire roller bearing and washer races were covered
with rust. The rollers appeared to be scored up also. Shouldn't
it be lubricated? I rechecked the assembly instructions and
did not see mention of lubricating the thrust bearing. I have
a very dry basement. Maybe the moisture came from the plywood
support and rusted the unlubricated bearing. I guess there was enough
friction from the rusted bearing to shear the pin on the motor shaft.
