Lubrication on newer "dry head" machines

[R8R]

Same thing on the used LK-1900A I just got, but there are FOUR different recommended greases. WTF?

A decent alternative lube is TriFlo grease. It’s a touch thinner than white lithium, but soooo slippery. I like it for used machines because it will loosen up a dry head making it quieter and smoother. It also doesn’t get pushed out with rotating components like thicker lubes do.

Good to know. I am partial to Synco Super Lube ptfe grease. M&R specs it for their automatic screen printing presses, it's all I used for years, zero parts failures with it.

For a Juki...is four different greases really a required thing though?

Juki’s come out of many different factories. Some are still made in Japan, most in China. Garment machines require lube that can be cleaned out of fabrics with an atomizer gun and solvent. Most lubes don’t meet this requirement so you end up with a bunch of oddball stuff nobody recognizes. The dry head system was developed because the machining tolerances are poor on the Chinese units, they couldn’t keep oil in the heads and it was costing factories a lot of money for cleaning sewn goods. They sold the catch phrase dry head when it should be called “we can’t keep the oil in”. The different lubes are likely a result of regional factory locations. Juki A is your best bet, it’s the most common over all their many classes.

Thanks! So I can assume diagrams like this pointing to 3 different greases are being a little ridiculous. Do they really expect anyone to apply different lubes like this in the field?

In the past manuals of Juki, their lubrication and grease has been listed in several ways. Particulary I have noticed the manual would say: In assembly. In other manuals of operaters or their engineer tech manual they would have : In the event of disassembly and the “ reassembly “ use type ~

In my searching in the past these types have been brought up, but honestly I havent seen any great clarification on machine specifics covering all their machine line. Typically individual machinery.   

Although it is my experience with equipment you could relate the specific part number and its “qualified” alternative. This can possibly be easier to understand its placement usage in a machinery situation. 

I am a big promoter of a companies designed lube choice, as It was a costly expense for them to decide best for their machinerys durability.

 

Good day
