Provided is a lubricant composition including a bicyclic liquid crystal of formula (1), and a tricyclic liquid crystal compound of formula (2), and having a mixing mass ratio of the bicyclic liquid crystal compound and tricyclic liquid crystal compound of 95:5 to 15:85. The composition is suitable for use in a clean environment, under a high vacuum, under high temperature and a bearing. R1 and R2 are the same or different from each other, and each is —OCH2CH2CH(R′)CH2CH2OR R11 and R21 are the same or different from each other, and each is —OR. R12, R13, R22 and R23 are the same or different from each other, and each is hydrogen or —OR. R is a linear or branched CnH2n+1, 1≤n≤20 and R′ is methyl or ethyl.
A lubricant composition which comprises a bicyclic liquid crystal component and a tricyclic liquid crystal component, wherein the bicyclic liquid crystal component consists essentially of at least one kind of a bicyclic liquid crystal compound represented by the following formula (1) and the tricyclic liquid crystal component consists essentially of at least one kind of a tricyclic liquid crystal compound represented by the following formula (2), and a mixing ratio of the above-mentioned bicyclic liquid crystal compound and the above-mentioned tricyclic liquid crystal compound is 95:5 to 15:85 in a mass ratio,
