Rolling bearing |
| abstract |
The acoustic characteristics and lubrication performance of a grease-lubricated small-diameter rolling bearing are improved. The surface roughness of a raceway surface 2a of an outer ring 2, a raceway surface 1a of an inner ring 1, and a ball 3 is 0.015 μm or less in terms of arithmetic average roughness. As a grease, silica particles having a hydrophobic surface and an average primary particle size of 100 nm or less are contained in a proportion of 0.01% by mass or more and 10.0% by mass or less, and the blending degree is 280 or more. A base oil having a kinematic viscosity at 40 ° C. of 20 mm 2 / s or more and 200 mm 2 / s or less is used. [Selection] Figure 1 |
