Semi-liquid grease for fifth-wheel and open gears
The GW-5 fifth wheel and open gears semi-liquid grease outperforms all other similar greases on the market.
Characteristics and Benefits
The GW-5 unique formulation includes the following elements:
- Graphite and molybdenum disulphide compound;
- Overbased calcium sulfonate complex;
- PROLAB's ANTIFRICTION TREATMENT;
- Adherence agents;
- Superior quality mineral oil base.
Its exclusive PROLAB formula brings the GW-5 fifth wheel and open gears semi-liquid grease to an exceptional level of performance: it is super adherent, it reduces friction, protects against rust, corrosion and oxidation, provides exceptional load, shock, impact and washout resistance and ensures excellent mechanical stability. GW-5 provides substantial savings by allowing for less frequent grease changes. Specifically developed for ground transportation, the GW-5 fifth wheel and open gears semi-liquid grease has been tested under the harshest performance conditions, including: extended service intervals, severe operating environment such as mining and forestry, excessively long hauls, redistribution network tractors, etc. In every one of these severe tests, the GW-5 demonstrated outstanding adherence and resistance to breakdown. It is available in semi-liquid form which makes it easy to apply.
Types of Application
The GW-5 fifth wheel and open gears semi-liquid grease is a must for trucking companies and for companies operating open gears equipment. It is ideal for greasing fifth wheels and landing gears and provides excellent results on open gears.
The GW-5 is compatible with Teflon linings and considerably extend their service life.
Directions for Use
GW-5 can be easily applied with a brush, a roller, an atomizer or by simply pouring. On fifth wheels: thoroughly clean the fifth wheel before application so as to ensure metal saturation. Application should be made in a garage with controlled temperature. On open gears: GW-5 provides excellent results in equipment with rotational speeds of less than 800 rpm.
Whenever performing a grease change, make sure to validate the compatibility of the various greases used (refer to PROLAB's grease compatibility chart).
