摘要:
The rolling device of the present invention is a rolling device that is equipped with an inner ring, an outer ring, and a plurality of rolling elements disposed between the inner ring and the outer ring so as to freely roll, and that is packed with a lubricant composition containing a gelling agent in which a difference between a worked consistency and an unworked consistency is 40-130, and this rolling device has low-torque characteristics, is excellent in terms of recovery property and heat resistance, is free from lubricant leakage, and has a long life.

摘要:
Ein synergistischer Effekt auf das Viskositätsverhalten von Ölen wird durch Zusatz einer Kombination aus 0,1-10 Gew.% eines hochschmelzenden Fettsäureglycerids von gesättigten Fettsäuren (C₁₄₋₂₄) mit einem Schmelzpunkt von mehr als 50°C (A) und 0,2-10 Gew.% einer hochdispersen Kieselsäure (B) im Verhältnis A:B= 20:80 bis 80:20 erzielt. Eine deutliche Viskositätserhöhung läßt sich mit relativ geringen Mengen von 0,1-1,0 Gew.% (A) und 0,2-2 Gew.% (B) erreichen; zur Erzielung pastöser Konsistenz sind Zusatz mengen von 1 Gew.% (A) und 2 Gew.% (B) erdorderlich (Mengenverhältnis A:B= 25:75 bis 50:50).
