The invention relates to a blower pitch bearing lubricating grease which comprises the following components in parts by weight: 9.1-10.5 parts of 12-hydroxystearic acid, 3.9-4.5 parts of hydrogenated castor oil, 1.9-2.4 parts of lithium hydroxide, 75.9-82.3 parts of base oil, 1.5-3.5 parts of extreme pressure antiwear additive, 0.5-1.5 parts of antioxidant, 0.5-1 part of rust inhibitor and 0.3-0.7 part of metal passivator. Compared with the prior art, the invention can perform long-acting lubrication and protection on the generating equipment blade pitch bearing in low-temperature, high-temperature, high/low-temperature alternate variation, rain and snow, sand dust and other harsh environments, can perform dynamic repair on friction positions subjected to abrasion and pitting corrosion in the operation process, and solves the technical problems of limited service life, environmental pollution and the like in the existing wind power equipment lubricant.
