[0031] Example 1

[0032] In this embodiment, a nano-diamond roller bearing oil is composed of the following parts by weight:

[0033] 29.5 parts of metallocene PAO200C;

[0034] 21 parts of alkyl naphthalene;

[0035] 20 parts of high-performance complex calcium sulfonate grease;

[0036] 8 parts of nano-diamond dispersion with lipophilic surface modification;

[0037] Aromatic amine antioxidant 1.0 part;

[0038] 6.5 parts of polyisobutylene PIB1100;
