Low friction pulley for thrust stand

Low friction pulley for thrust stand

Low friction pulley for thrust stand

(OP)
I am in need of a relatively small, very low friction pulley.  It will be used to calibrate a thrust stand in real-time.  I saw an old thread on here that was talking about the same thing but it was closed. thread406-60789: low friction pulley  Any advice on what I could use and a site where I could get it would be helpful.

RE: Low friction pulley for thrust stand

Think about setting up your thrust stand to have the thruster oriented vertically.  Calibration then requires just placing/removing a mass (and knowledge of local "g").

But, you are probably working, as I once did, on an existing thrust stand.  www.wmberg.com has small low-friction pulleys and ball bearings, you may also find some at www.mcmaster.com

RE: Low friction pulley for thrust stand

You have to determine whether this is a THRUST LOAD application or RADIAL LOAD before you buy any bearings....
You can get low-friction, radial capacity, or thrust capacity.  NOT all 3 in same bearing unless load is VERY low compared to the bearing RATED load.
