STORAGE

 

 
Units shipped from Brawn Mixer are intended to be used 
within 30 days after receipt and presumed to be stored 
indoors in a heated building. Store mixers as packaged 
by the factory. If you intend storing units under adverse 
conditions or for a long period of time, special storage 
precautions will be necessary. 

 
1.  Store in a sheltered area away from chemical vapors or 

steam. 

2.  Cover. 
3.  Do not store in sunlight or near high heat. 
4.  Spray oil on exposed shafts and seals.  Remove oil on 

start-up. 

5.  Rotate output shaft 360º every 3-4 weeks. 
6.  Mixers should not be stored near vibrating machinery 

to avoid damage to the bearings. 

7.  If electric motors have been subjected to humid 

conditions, check the insulation resistance between 
phase and mass and between the different phases. 
The resistance should not be less than 100 
megohms. If the resistance is less, please consult 
the factory 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

BWG GEARBOX FEATURES

 

 

[SEE FIGURE ON PAGE 9] 

 

1. 

Rugged Cast Iron Housings

 provide superior 

strength and rigidity. 

Generous Oil Capacity

 assures lower operating 

temperatures and maximum gear, bearing and seal 
life. 

 

2. 

Hardened and Precision-Ground Worms

 are cut 

integral with the shaft.  High helix angles provide the 
ultimate in efficiency and torque capacity. 

 

3. 

Cast Iron Bearing Covers

 on the input shaft provide 

greater reliability when subjected to high start-up or 
reversing loads. 

 
4. 

Tapered Roller Bearings

 provide greater overhung 

load and thrust capability, ensuring maximum life. 

 
5. 

Chill-Cast Bronze Gears

 give you the long, trouble-

free life and high quality you expect from Brawn 
Mixer drives. 

 
6. 

Output Oil Seal

 keeps the lubricant in, contaminants 

out. Maintenance costs are reduced. 

 
7. 

Alloy Steel Output Shafts

 provide extra strength for 

your rugged applications. 

 

LUBRICATION 

Splash Lubrication

 provides positive protection for 

gears and bearings. 

 

Splash Guards

 are furnished to prevent oil from leaking 

through the vent.
