SUGGESTED CHEMICALS FOR OFF-ROAD CARS

 

#106220 HUDY Bearing Grease 

• extended-life multipurpose lubricant for ball bearings 
• direct replacement for the grease delivered in ball-bearings
• combines an optimized additive package with proven 

synthetic-base oils and a robust lithium complex thickener system 

• provides outstanding protection against wear, rust, high 

temperature degradation and demanding startup and heavy 
loading conditions.

#106221 HUDY Bearing Grease – Extra

• advanced lubricant incorporating both extreme pressure 

additives and finely dispersed graphite for load carrying

• advanced replacement for the standard bearing grease
• formulated to have excellent adhesion and resistance 

to “fling-off” under extreme conditions

• provides outstanding protection against wear, rust, high 

temperature degradation and demanding startup 
and heavy loading conditions

#106222 HUDY Bearing Grease - Premium

• supreme-performance lubricant for extreme overload conditions 

in highly-loaded bearings

• combines the unique features of synthetic-base fluids with those 

of a high-quality lithium complex thickener

• wax-free nature of synthetic fluids and low coefficient 

of friction provide very low running torque.

• reduces operating temperatures in the load zone 

of spherical roller- and ball-bearings

• lithium complex thickener contributes excellent adhesion, 

structural stability and resistance to water

• high level of chemical stability, formulated with special additive 

combinations to provide excellent protection against wear, rust 
and corrosion at high and low temperatures

#106210 HUDY Graphite Grease

• high-performance, advanced-technology semi-fluid
• special formulation provides outstanding load-carrying 

and anti-wear properties

• superior protection against wear, resulting in reduced 

gear replacement costs and increased part life

• efficient operation, good low temperature start-up 

and reduced energy consumption 

• very good protection against rust and corrosion
• very good adhesion reduces fling-off and consumption

#106211 HUDY Diff Grease

• high-performance, model racing car general-purpose silicone based 

grease, formulated to provide extra protection against wear, 
corrosion, and water

• excellent resistance to thermal, oxidative 

and structural degradation

• extended grease life and improved bearing protection
• excellent resistance to water wash-out and spray-off 
• assures proper lubrication and protection in wet environments
• excellent rust and corrosion resistance
• very good anti-wear properties

#106230 HUDY Bearing Oil

• high-quality HUDY Bearing Oil is used to lubricate bearings 

for ultra-smooth operation and long lifespan

• very good for use on dusty tracks and carpet tracks because it 

helps combat the effects of dust and carpet hair contamination

• super thin to help promote quick penetration 

and fast & easy coverage

• recommended for use immediately after bearing cleaning 

(e.g. with spray cleaner)

XRAY Premium Silicone Oils

• high-quality, lab-certified line of oils 

that will make "dialing in" quicker and easier

• created exclusively for XRAY by a specialized 

European silicone oil premium manufacturer

• each batch of premium oil is laboratory tested 

and calibrated to ensure the highest possible consistency 
and quality from batch to batch

• based on industry-proven CST rating
• smart bottle design for quick identification and easy shock filling
• entire range of oils from 100–300,000 cSt for shock absorbers 

and gear differentials
