<p>A grease-sealed bearing for inverter drive motor that is inexpensive and is capable of effectively inhibiting any damage by electric corrosion. Grease-sealed bearing (1) for inverter drive motor is a bearing comprising inner race (2), outer race (3), multiple rolling elements (4) interposed therebetween and seal member (6) covering the axial-direction both end openings of the inner and outer races, with grease (7) sealed around the rolling elements, wherein the grease (7) is one obtained by mixing an additive containing an electric corrosion inhibitor on at least a bearing rolling plane into a base grease composed of a base oil and a thickening agent, and wherein the proportion of electric corrosion inhibitor mixed is in the range of 0.05 to 10 parts by weight per 100 parts by weight of base grease.</p> |
