Hi Jan,

This is what my GCC Spirit manual says (I use PS2 grease)

"In order to keep the motion system running smoothly, the X / Y rails of the motion system will need lubrication on a semi-regular basis. Use a small amount of light grade machine oil or PS2 grease to a paper or cotton towel and apply to the rails. You can purchase PS2 grease from NSK dealers worldwide"

Regards,
Hannu

Hello

Thanks for the reply. I buy lithium grease.
This is but for axis X. I still need to grease the ball bearings
and pulleys. It also lithium grease?

Thanks

It will be better idea to change the bearings to new than regrease those. The bearings are totally closed and those are not meant to grease again.

Hello

I can not find a seller "lithium PS2" in ČR.
In the store, I found this:

http://www.motorex.com/index.cfm?oid=1158&lang=en&webtoolDbTemp=eintragDetail&eintragId=168

It can be used?

Thanks

It must be cheaper in the Czech Republic, the local NSK distributor wants almost $90 USD for an 80g tube... If anyone has found it cheaper I'd sure like to know where!

Gary,

Amazon has 100g tube for 14.95 ----------------Google " Motorex White Grease"

Its hard belive that something is cheaper in CZ than in US because we have almost everything more expensive ;) From my point of view is price about 30 USD for grease is bloody expensive ... common white grease cost about 2-5 USD for 250g from CZ producer .. but we want the best for our laser pets :D

That's close but not quite the same, not all "lithium based" grease is the same. I bought some very similar to Motorex and the consistency is worlds apart from the PS2 lube from NSK, the NSK is very thin and the typical lithium grease is pretty thick, more viscous.
