The invention discloses a side bearing used for a bogie. The side bearing comprises a side bearing body (1) connected with a swing bolster of the bogie, and further comprises a top cover (2) and a partition plate (3) which are arranged above the side bearing body (1). The side bearing body (1) is connected with the top cover (2) through a rubber blanket (11), so a sealing chamber is formed. The partition plate (3) is arranged between the side bearing body (1) and the top cover (2) and separates the sealing chamber into a lower chamber (a) and an upper chamber (b), a throttling hole (31) communicated with the lower chamber (a) and the upper chamber (b) is formed in the partition plate (3), and vibration reduction liquid is filled in the lower chamber (a). The side bearing can reduce the transverse swing speed of a car body when the car body rolls laterally and further plays a role in vibration reduction, vibration reduction capacity of the side bearing is strengthened, and working stability of the bogie is further improved. The invention further discloses the bogie comprising the side bearing, and the bogie has corresponding effects.
