Description
Klüber VARILUB NBU 15-300 – Spindle bearing grease –
Description:
VARILUB NBU 15/300 is a high-speed grease with good pressure absorption properties. It consists of ester oil, synthetic hydrocarbon oil and mineral oil as well as a barium complex soap. VARILUB NBU 15/3000 offers good corrosion and wear protection, resistance to water and media as well as ageing and oxidation stability.
Benefits for your application:
– Savings in costs for bearings due to the good corrosion and wear protection as well as pressure absorption capacity of the grease, therefore long service life and maintenance intervals
– Reduced wastewater disposal costs due to good water resistance resulting in a long service life and relubrication intervals
– Trouble-free operation of machines due to easy pumpability and metering in central lubrication systems
Application:
VARILUB NBU 15/300 has been especially developed for highspeed rolling and plain bearings, e.g. tool and textile spindle bearings, threaded spindles, ball screws subject to high loads, chassis bearings. It can also be used as long-term grease for bearings in cableways and precision engineering, or for the lubrication of tooth flanks in precision gears (e.g. bevel gears in milling machines, electromechanical actuators for valves).
Application notes:
The lubricant is applied by brush, spatula, grease gun or cartridge. Owing to the many different elastomer and plastic compositions their compatibility has to be checked prior to series applications.
The product can normally be applied by means of centralised lubricating systems. Please note, however, that due to different system configurations and application conditions the pumpability of the product has to be confirmed for each individual application. We will be pleased to provide assistance in this matter.
