The invention relates to the technical field of wind power generation, and particularly discloses a bearing oil injection device which comprises a main bearing installed on a bearing seat, an adapter with internal and external threads is installed on the bearing seat, the upper portion of the adapter abuts against an oil injection pipe flange so that the adapter can be screwed up and down, and an oil injection pipe can be adjusted to the preset height. And therefore, the contact part of the upper roller of the main bearing and the inner ring raceway is lubricated by oil injection. The bearing oil injection device is good in universality, can be used for different types of main bearing retainers, such as an integrated frame type retainer and a pin penetrating type retainer, and rollers and raceways with different contact heights, can avoid the problem of multi-structure configuration caused by different development progresses of different suppliers and different oil injection height requirements, and is suitab
