Ceramic Ball Bearing Grease

Description:

SEIVIO Braolub F783 Ceramic Ball Bearing Grease is formulated with fully synthetic special base oil, complex soap thickening, and a unique polymer system. It is a special grease specially adapted to hybrid ceramic ball bearings (steel inner ring + steel outer ring + ceramic rolling elements, the most common Si3N4 silicon nitride ceramic balls).

Benefits:

Form a high-strength boundary film under high Hertz contact stress to avoid pitting and spalling;
No-load noise can be reduced by 3~5dB(A) when running above 5000rpm, suppressing high-speed friction temperature rise;
After long-term high-frequency compound exercise, the consistency changes little, and it does not soften, extrusion, or harden to failure;
No corrosion to silicon nitride ceramics, bearing steel, stainless steel and various engineering plastic cages;
It starts smoothly at low temperatures and does not produce oil or coking at high temperatures, allowing for a long maintenance-free period;
It has no adverse reactions with sealing materials such as fluororubber and nitrile rubber, and is suitable for closed systems.
