F4-9G (F4-9M) Miniature Thrust Bearing 4mm x 9mm x 4mm
A thrust bearing is a particular type of rotary bearing. These bearings consist of three parts, a shaft and housing washer which have annular grooves machined into them and a caged ball bearing assembly which is sandwiched between the two washers. Assembly and mounting is quite simple as the parts are able to be separated.
