The utility model discloses a mute pressure bearing for a door hinge, which adopts the novel design that steel balls are uniformly embedded in an integrally formed plastic retainer, and the steel balls are enclosed and surrounded by upper and lower concave sheets outside the integrally formed plastic retainer to jointly support the movement of the steel balls, so that the noise generated by long-time use of the door hinge is greatly reduced, the service life of the bearing is effectively prolonged, and meanwhile, the mute pressure bearing is simple and convenient to mount and low in cost. The production cost is reduced. 本实用新型公开一种用于门铰静音压力轴承，通过一体成型的塑料保持架均匀内嵌钢球,外部由上下凹片封闭包围钢球,共同支撑钢球运动的新颖设计,大大降低了门铰长时间使用产生的噪音，有效提高了轴承的使用寿命，同时安装简便，降低生产成本。
