Kluberquiet BQ 74-73 N

Manufacturer: KLÜBER LUBRICATION (Germany)
Low-noise rolling bearing grease for the long-term lubrication of high-speed rolling bearings
Kluberquiet BQ 74-73 N is a rolling bearing grease based on synthetic hydrocarbon, ester oil and urea. It was especially developed for the lubrication of high-speed ball bearings operating at high temperatures.
With its unique combination of carefully selected raw materials, Kluberquiet BQ 74-73 N offers:
  • low-noise operation proved in tests on noise test rigs such as SKF BeQuiet
  • long bearing life
  • wide service temperature range with excellent low-temperature characteristics
Benefits for your application
  • Lifetime lubrication of vertically mounted bearings subject to high speeds and/or with a rotating outer ring
  • Low-noise spindle bearing grease, also for motor spindles

Features, Application
Synthetic long-term grease for rolling and plain bearings, linear motion guides
ISOFLEX TOPAS NCA 52 is a synthetic long-term grease with good low-temperature properties. It has a good load-carrying capacity and ensures smooth running even at high speeds and accelerations.
The thickener made of special calcium soap ensures good adhesion to the component and good resistance to media. The additives contained in ISOFLEX TOPAS NCA 52 increase wear protection.
Special low-temperature greases
ISOFLEX TOPAS L 32 and L 32 N have been designed for extremely low temperatures. These greases consist of a synthetic hydrocarbon oil and a special lithium soap. ISOFLEX TOPAS L 32 and L 32 N are resistant to ageing and oxidation and provide good corrosion protection as well as water resistance.
ISOFLEX TOPAS L 32 N also contains a UV indicator, which ensures quality checking even with minimum quantity lubrication.
Synthetic low-temperature greases with a light-coloured solid lubricant
Klubersynth LF 44-22 and Klubersynth LF 44-32 are synthetic, dynamically light low-temperature greases containing anticorrosion and antioxidation additives. They are based on synthetic hydrocarbon oil and a special lithium soap thickener. The greases, which are designed for very low temperatures, are resistant to water and contain a friction-reducing solid lubricant.
Synthetic refrigeration compressor lubricant
Klüber Summit RAB 68 is based on synthetic hydrocarbon oils and special additives. It is very stable at high temperatures while providing excellent low temperature properties at evaporator temperatures below -45°C. The solubility with the refrigerants listed below is excellent and the deposit formation and foaming tendency is considerably reduced compared to naphthenic refrigeration compressor oils.
Electroconductive low-noise rolling bearing grease for long-term lubrication
Kluberlectric BQ 72-72 was developed as an electroconductive rolling bearing grease with added excellent low-noise characteristics. Due to the use of selected additives based on ionic liquids, the lubricant's electroconductivity was increased, attaining resistance characteristics resembling those of semiconductors.
Low-noise rolling bearing grease for long-term lubrication
Kluberquiet BQ 72-72 is made up of an ester oil, a polyurea thickener and special additives. These components have been combined such that Kluberquiet BQ 72-72 offers many advantages for the lubrication of rolling bearings.
