Provides positive "quick close" by pulling grease back from nozzle tip after dispense
Minimizes or eliminates oozing or drooling of grease from nozzle tip
Makes use of nozzle motion for actuation of snuff-back
Causes positive "quick open" by instantly supplying grease to nozzle tip at start of dispense
Compensates for the compressibility of grease and swelling and bending hoses
Includes "tip to part" distance control adjustment with lock nut
BEFORE
System peculiarities cause messy nozzle tips and unacceptable grease dispensing.
After-bleed or oozing caused by hose or compressible grease
Grease may not stick to part because nozzle is too far from part
Grease sticks to nozzle that is too close to part
AFTER The snuff-back nozzle solves these problems by pulling grease back inside nozzle and precisely controlling nozzle "tip to part" distance. With the snuff-back nozzle, grease dispensing will look like this.
Perfect Dispense
Clean Nozzle Tip
The SBN-1000 nozzle has "tip to part" adjustment and includes spring loaded
piston to pull (snuff) grease inside nozzle as nozzle is moved away from part.
Nozzle has 1/8 NPT grease inlet and 1/4" OD (0.191" inside diameter) tip and functions
with NLGI 000 through 3 grease with volumes between 0.040 and 3.00 cc.
TYPICAL APPLICATION: Nozzle will mount on user's motion device
(often a non-rotating air cylinder) with a stroke of 1" or more.
As cylinder extends, snuff-back actuator contacts part and stops movement at
adjusted setting. When cylinder retracts, snuff-back causes clean break and clean nozzle.
