Klüberlub BE 41-1501 is a heavy-duty grease for highly-loaded rolling bearings operating at low speeds
Product information
FAG FE 8 tests have confirmed the effectiveness of Klüberlub BE 41- 1501 under these conditions and it is approved by various bearing manufacturers, e.g. FAG, to be used for applications in low-speed rolling bearings subject to very high loads and shocks, for example in roller presses and bowl mill crushers.
If the lubricating film becomes adversely stressed under extreme conditions, e.g. during high levels of oscillation and friction, the solid lubricants MoS2 and graphite contained in Klüberlub BE 41-1501 ensure excellent emergency lubricating properties providing additional reliability in the event of starved lubrication.
The product also provides good corrosion protection and is compatible with seals, e.g. made of NBR elastomers. Klüberlub BE 41-1501 is approved by leading component OEMs, e.g. Flender and David Brown.
Features
Klüberlub BE 41-1501 is designed to meet the requirements of rolling bearings subject to extreme conditions. The appropriate ombination of base oil and additives enables improved wear protection.
Klüberlub BE 41-1501 was developed for highly-loaded large rolling bearings running at low speeds as well as toothed gear systems such as industrial and rail traction gear couplings.
Typical applications and requirements include: spherical roller bearings in roller presses, bowl mill crushers and rotary crushers in the mining and base materials industries. The operating conditions of roller bearings require use of a heavy duty grease with high base oil viscosity with suitability for the following conditions:
- low speed, n = 10-30 rpm
- high load, P/C = 0.25 - 0.50
- bearing temperature approx. 50-70 °C
- shock loading and vibration
Owing to its excellent lubricating properties, Klüberlub BE 41-1501 can also be used successfully for the lubrication of pivoting bearings, plain bearings and industrial gear couplings.
Benefits
- Excellent wear protection under the highest dynamic load conditions
- Good load-carrying capacity at low rotational speeds
- Reliable lubricant film formation at high service temperatures
- Emergency lubricating properties due to the addition of special solid lubricants

Directions for use
When using Klüberlub BE 41-1501 with automatic grease pumps, the ambient temperature should be ≥ 15 °C.
Klüberlub BE 41-1501 has been tested and verified for use with selected plastics and elastomers, however, we recommend checking compatibility prior to series application to ensure reliable equipment operation.
