KLUBERSYNTH BM 44-42

Trouble-free function of component across their entire lifetime without relubrication is a frequently encountered requirement of highly-developed applications such as Drive by Wire technology. Klübersynth BM 44-42 offers both manufacturers and operators of such components and systems the matching solution for long-term lubrication.

Additionally, extreme requirements such as smooth operation at low temperatures and low-wear operation at high surrounding temperatures are to be met.

Klübersynth BM 44-42 offers a low start-up torque for trouble-free operation and enables energy savings.

Rolling bearings and other components can be operated at shortterm peak temperatures without severely affecting the product's lubricity.

Should your application be subject to vibrations or higher loads, Klübersynth BM 44-42 can protect your component against premature failure and wear. Its good sealing capacity and miscibility with conventional bearing lubricants makes Klübersynth BM 44-42 a versatile speciality lubricant for many applications

Klübersynth BM 44-42 is mostly used for the long-term lubrication of actuators and rolling bearings in automotive applications. It was also developed for low-wear idling operation and reliable indexing of free-wheels and override clutches. Klübersynth BM 44-42 shows good adhesion to the lubrication point, improving long-term lubrication especially in uncapped bearings or rotating outer rings.
Klübersynth BM 44-42 can be applied by brush, spatula, grease gun or automatic metering equipment. Pumpability in automatic lubricating systems is subject to tests and prior consulting. Please ask our experts for details.

Long-term grease for less maintenance and for-life lubrication
Extensive range of applications due to wide service temperature range
Longer component life due to optimised oil release and anti-wear additives
