Abstract
The present disclosure relates to optical systems and related devices, specifically those related to light detection and ranging (LIDAR) systems. An example optical system includes a housing, a shaft defining a rotational axis, and a rotatable optical component coupled to the shaft. The optical system also includes a first rotary bearing having an inner race, an outer race, and a plurality of rolling elements configured to roll between the inner race and the outer race. The inner race is coupled to the shaft and the outer race is coupled to the housing. The optical system also includes a preload mechanism having a spring coupled to the housing and a preload distributor coupled to the spring and the outer race. The spring is configured to apply an axial preload force to the outer race through the preload distributor.
