Description
Klüberquiet BQ 72-52 Low-noise high-temperature grease for high-speed rolling bearings | N° 094150
- As a manufacturer of precision bearings, you have to meet customers’ stringent requirements on both bearings and their lubricants. Besides fault-free bearing operation, long relubrication intervals or even for-life lubrication are frequently requested.
- Modern technology has strongly influenced the requirements to be met by rolling bearings: extremely low-noise operation over a wide service temperature range, combined with high to extremely highly speeds, even at high ambient temperatures. With this extraordinary set of requirements, Klüberquiet BQ 72-52 offers optimal support.
- Temperature range: -50°C to +180°C
- Pack size: 1 kg can
- Also available in: 400 g cartridge, 25 kg bucket
Benefits for your application
- For-life lubrication enabled by good ageing stability and wide service temperature range
- Proven smooth running in noise-sensitive applications
- Increase in efficiency due to low friction values also at high speeds
- Cost savings due to long useful life of the grease
Applications
- Klüberquiet BQ 72-52 is preferably used for the long-term and forlife lubrication of capped or sealed ball bearings where the particular challenge is posed by high speeds combined with a wide temperature range and the demand for low-noise operation. Such bearings are often part of noise-sensitive, small electric motors, for example in office machines, household appliances like vacuum cleaners, or consumer electronics.
- Other applications are in fan bearings or electric drives and actuators in vehicles. Furthermore, sliding points in precision equipment as well as in vehicles, such as locking systems or seat adjustment mechanisms requiring low oil separation, can be reliably lubricated with this grease.
Application notes
- Klüberquiet BQ 72-52 may be applied by brush, spatula, grease gun or grease cartridge. We recommend removing any preservatives prior to greasing. The preservative to be used must be checked for purity and its chemical composition for compatibility with Klüberquiet BQ 72-52. Talk to us – we will be pleased to advise you.

Product description
Based on many years of experience in the field of low-noise technology, Klüberquiet BQ 72-52 was developed with these applications in mind. The low noise level attainable with Klüberquiet BQ 72-52 was proven on all standard test rigs. The carefully composed ingredients and the thermally stable synthetic base oil mixture of Klüberquiet BQ 72-52 offer you multiple benefits in the lubrication of rolling bearings. Examples are the reduction of friction through optimised oil release and the protection of the rolling bearing due to the product’s excellent antioxidative and anticorrosive behaviour.
