Thread: Spindle Grease
Threaded View

I working with a china vertical mill/drill, ZX50 clone.
The gearbox is a 4 speed unit.
The spindle needs lubricated with grease via a nipple on the front.
When i use the mill on it's fastest speed, which i need for steel.
Grease starts to egress via the lower bearing and drops on to the work.
The spindle is not getting hot - i read about 40C after it's been running for 30mins.
(i can imagine that the inner temps of the bearing will be higher)
Can anyone suggest -
a) a better grease that won't drop out
b) some other type of cure.
thanks
