What is the proper lubricant for Graphotype Machines?

Black Gold, Texas Tea – Oil – Which is the right for me?

The Addressograph Multigraph Company said the ONLY lubricant that should be used with Graphotype machines was DURO-VIS.  DURO-VIS was oil that was produced for and marked by the A-M Company up until their closure in the 1980’s.

DURO-VIS OIL CAN

DURO-VIS OIL CAN

The official designation of this oil was:
AM INTERNATIONAL, INC., MULTIGRAPHICS DIV.
DURO-VIS/LUBRICATING OIL, PART #:MA-78A, MA-81A
NSN: 9150-00-953-7364

Ok, what is the point of all this information if Addressograph-Multigraph is no longer in business?  We visited with people that knew what DURO-VIS was and people that knew the chemical composition of DURO-VIS they indicated to us that the oil was highly refined 20 weight oil with several special additives that would not attack the bronze bushings and bearings in the Graphotype machine.

DURO-VIS has very similar properties of SAE20 – none detergent oil.

“ DURO-VIS is not Automotive Oil – it is not 10w30 or some other multi-weight oil.
“ DURO-VIS is not Sewing Machine Oil
“ DURO-VIS does not have tackifiers such as Lucas Oil – tackifiers used in this type of equipment will damage the bearings and will not lubricate the machine correctly.
“ DURO-VIS does not contain paraffin’s, wax or soluble wax based emulsifiers added to the lubricant.
“ DURO-VIS does not have additives that attack bronze or bronze based products such as bearings, gears, races, etc.

BUY DURO-VIS:

Where can I get DURO-VIS Oil for my precious Graphotype machine?  At present there are two sources of DURO-VIS Oil.  One is a printing press supply company that only sells it by the case with a minimum order of two cases or you can purchase it from Bruce in his eBay store (eBay – Username: TristateUSA).

TristateUSA Superstore
eBay Username: Tristateusa
Phone Number: 812-744-1060
Store Owner: Bruce

Currently Tristateusa is offering DURO-VIS in 6oz and 2oz bottles.  Please visit their eBay store for current pricing.

Graphotype.net recommends DURO-VIS oil at this time for all Graphotype machines until we can find a commercial equivalent available on the open market.

BRONZE THOUGHTS:

Bronze is considered a yellow metal and it has been used for years as a bearing surface because of it’s unique wear properties.  Just as bronze is a different color than steel it reacts differently to chemicals and lubricants than does steel.

It is important to note that Graphotype machines have many bronze bushings, gears and parts, these bronze parts can be attacked and destroyed by certain types of oils and lubricants available in the commercial sector.  All lubricants are NOT the same, oil is not just oil as many believe – if you care about your equipment you need to educate yourself and use the correct lubricants or you will damage or destroy your equipment.

SEWING MACHINE OIL:

It is important to note here that some sewing machine oils also contain additives that do NOT react well with bronze.  Do not use just any oil available.  Do not use sewing machine oils that have a paraffin base.  Not all sewing machine oils are bad for Graphotype machines but you as an operator must educate yourself to find out which ones are safe and which ones are not.  Don’t just ask the sales person at the local hardware store or sewing machine supply house, make sure you read the data on the sewing machine oil itself.  If in doubt ASK, or review the MSDS (Materials Safety Data Sheet) that should be avaliable with any and all chemicals and lubricants.

THE CLUTCH:

Another note is that there are 20 discs in the clutch, 10 of steel and 10 of Bakelite, the use of the wrong oil in the clutch can cause degradation of the Bakelite discs to where they will disintegrate.  No oil in the clutch is also a major cause of premature clutch failure.  With no lubricant in the clutch the steel discs will wear the Bakelite discs away.  You do not want to use an oil such as 3-in-one as this lubricant contains paraffin and it will build up on the surfaces of the clutch and discs and cause the clutch to not work correctly.

TAKE CARE OF YOUR GRAPHOTYPE AND IT WILL TAKE CARE OF YOU.
