Klüber Klübersynth BM 44-42
Special grease for actuators, rolling bearings and free-wheels
Application Klüber Klübersynth BM 44-42
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.
Performance, Features & Benefits of Klüber Klübersynth BM 44-42 are:
- 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

Product Description Klüber Klübersynth 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 troublefree operation and enables energy savings. Rolling bearings and other components can be operated at short-term 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.
