Benterm 2 4.5 kg – high-temperature grease for rolling and plain bearings
Benterm 2 4.5 kg is an industrial NLGI 2 high-temperature grease formulated with high-viscosity mineral oil and a bentonite thickener. It is designed for lubricating rolling and plain bearings operating at elevated temperatures, particularly between 100°C and 200°C.
The 4.5 kg package is a practical choice for industrial facilities that regularly use Benterm 2 during scheduled maintenance and servicing of multiple bearing assemblies. The grease provides resistance to hot and cold water, low oil separation and corrosion protection.
Applications of Benterm 2
Benterm 2 is primarily designed for:
- lubrication of rolling bearings operating at elevated temperatures,
- lubrication of plain bearings in industrial machinery,
- maintenance of bearing assemblies exposed to temperatures up to 200°C,
- lubrication of bearings exposed to water or steam,
- scheduled industrial maintenance and periodic machinery servicing.
The manufacturer identifies temperatures between 100°C and 200°C as typical operating conditions for bearing applications. The declared overall operating temperature range of the grease is -20°C to +200°C.
Key benefits of Benterm 2 4.5 kg
- High-temperature resistance up to +200°C – designed for bearing lubrication under elevated-temperature conditions.
- Bentonite thickener – provides the non-melting characteristics associated with this grease technology.
- NLGI 2 consistency – suitable for specified rolling and plain bearing applications.
- Water resistance – resistant to both hot and cold water.
- Corrosion protection – helps protect lubricated metal components.
- Low oil separation – an important characteristic during high-temperature operation.
- Ageing resistance – designed to withstand prolonged exposure to elevated temperatures.
- 4.5 kg package – practical for regular use in industrial maintenance operations.
When should you choose Benterm 2 in a 4.5 kg package?
The 4.5 kg variant is particularly suitable for facilities where high-temperature grease is regularly used to maintain several machines or a larger number of bearings. Having a larger quantity available in one package helps maintenance teams plan lubricant consumption during scheduled servicing.
It is a practical option for industrial maintenance departments and service teams requiring a grease with consistent characteristics and documented technical specifications.
Important considerations before use
The manufacturer does not recommend Benterm greases for bearings driven by low torque. The technical documentation for Benterm 2 also identifies limitations concerning bearings with small radial clearance.
Before use, check the bearing manufacturer's recommendations, operating load, temperature, rotational speed and lubricant specifications.
When replacing an existing lubricant, verify grease compatibility and any requirements for cleaning the bearing assembly.

FAQ – Frequently asked questions
Is Benterm 2 suitable for bearings operating at 200°C?
Yes. The manufacturer specifies Benterm 2 for rolling and plain bearings operating at elevated temperatures, particularly between 100°C and 200°C.
Is Benterm 2 resistant to water?
Yes. Benterm 2 is resistant to hot and cold water. Its technical documentation also indicates applications involving exposure to water or steam.
When should I choose the 4.5 kg package of Benterm 2?
The larger package is worth considering when grease is regularly used to service multiple bearings and machines. It makes planning lubricant consumption during periodic industrial maintenance more convenient.
Can Benterm 2 be used in every type of bearing?
No. The manufacturer does not recommend Benterm greases for bearings driven by low torque. Restrictions concerning bearings with small radial clearance must also be considered.
Does Benterm 2 4.5 kg have different properties from Benterm 2 400 g?
Both variants contain Benterm 2 grease with the same declared technical characteristics. They differ primarily in package quantity and format. The 4.5 kg variant is intended for applications requiring a larger amount of grease.
Can Benterm 2 operate at 300°C?
No. The dropping point of 300°C is a laboratory test value and does not indicate the permissible operating temperature. The declared maximum operating temperature is +200°C.
