Is it OK to use MoS grease on bearings

Hi Folks,

I am cleaning out and repacking the bearings for the band rollers on bandsaw mill. There are 3, 32 x10 x 1/2"ID bearings in the roller and they had become dry and contaminated with sawdust.

My question is, is it OK to use grease (containing MoS) for high pressure applications or should I use proper wheel bearing grease?

The rollers run at up to 4000 RPM.

Thanks
