3. Why use a Bearing Gard?
Extend rotating equipment life and improve reliability with the Bearing Gard
Prevent contamination ingress
Extend oil and bearing life
Eliminate #1 cause of rotating equipment failure
Provide long term oil retention
Reduce bearing and lube operating temperature
Extend bearing and lubrication life
Improved housekeeping and safety
Added protection at shutdown
Shut-off O-ring blocks air transfer
Create a positive return on investment
An average investment of $400 per pump or motor can prevent maintenance or repair costs of $5,000 - $20,000 and more

4. Where do I use the Bearing Gard?
General bearing seal replacement (lip or labyrinth) in:
All types of non-flooded bearing seals in rotating equipment
Pumps: ANSI, ISO, API 610 and more
Electric motors: IEEE-841, severe duty, washdown and more
Gearboxes: non-flooded oil lubrication and grease

5. The Bearing Gard Completely Redesigned for World Class Performance

9. Key Features Unitization with axial runout
Improved unitization feature
Prevents shut-off O-ring binding
Axial runout up to 0.63 mm (0.025 in)
Exceeds competition’s standard axial runout of 0.13 mm (0.005 in)

10. Key Features Innovative shut-off design Improved static sealing
Tapered shoulder creates positive side wall sealing at all times
Dynamically lifts off to prevent wear at operational speed
Increased reliability by preventing O-ring binding
RPM

11. Bearing Gard A more reliable solution
Older design issues start at axial runout of 0.17mm(.007 in)
Minor binding with heat / wear
Major binding causes catastrophic drive o-ring failure
Extreme binding causes shaft damage and extreme heat

16. Bearing Gard Core Design
Core design easily retrofits where standard competitive designs were used

17. Bearing Gard Core Design
Ten questions to determine if the Bearing Gard ‘Core’ design is OK to use:
Is Shaft Diameter 0.875" " ( mm)?
Is Cross Section (Housing Bore - Shaft OD) 0.75" " ( mm) for shaft sizes up to inch (152 mm) or 1.00”-2.00” ( mm) for shaft sizes greater than inch (152 mm)?
Is Insertion of 0.325" (8.3 mm) for Housing Bore up to 5.375” (136 mm) or 0.375" (9.5 mm) for Housing Bore over 5.375” (136 mm) OK?
Is Protrusion of 0.375" (9.6 mm) OK?
Is the axial movement inch (0.63 mm) or less?
Is the radial shaft Movement inch or less (0.13 mm)?
Is the Shaft Speed less than 100 ft/s (30m/s)?
Is the oil Lubrication not flooded (oil level below shaft)?
Is the shaft Temperature less than 375°F (190°C)?
Are the Materials bronze and Viton?
If yes to all, the core design is OK to use
If no to any, contact Flowserve for an “Engineered” solution
