Rapid-Air AIR FEED / RAPID MASTER WITH KEYPAD - Manual (Page 5)


For a general guide for the Rapid Master,
the lubricator oil release adjustment
should be set to one drop of oil for
each 50-80 strokes. (See insert on
lubrication of “O” rings.)
LUBrICATION Of “O” rINgS
The “O” rings furnished with Rapid-Air
feeds are made of a Buna N Compound
designed to give long life on service with
air, oil and water. This rubber compound
features high abrasion resistance and
good dimensional stability if the recom-
mendations listed below are followed.
A filter and lubricator should be used; the
filter to remove grit that would otherwise
act as an abrasive, and the lubricator to
provide an adequate quantity of oil. For
best results, avoid an excess of oil.
Paraffin base oils in general will give the
best service. The viscosity should be 140-
170 S.S.U., the API gravity 29.5 minimum
and the aniline point between 150 F and
210 F. Variation of the aniline point from
the limits given is likely to cause either
shrinkage or stretching of the “O” rings.
DETERGENT MOTOR OILS AND ALL
OTHER OILS DESIGNED FOR AUTOMO-
TIVE USE ARE GENERALLY UNRELIABLE
IN CHEMICAL MAKEUP FOR USE WITH
RUBBER COMPOUNDS. SPINDLE OILS
ARE TOO LOW IN VISCOSITY.
The group of oils listed below are gener-
ally recommended for Buna N compound
366Y “O” rings. This grouping is given in
good faith but, because of the constant
changes made in oils by the manufactur-
ers, we cannot guarantee any consis-
tency of chemical makeup. All of these
oils have an aniline point of 210, and API
gravity of 29.5 minimum and a viscosity of
140-1 70 S.S.U. The base stock is paraffin.
