Abstract

A laser level includes a housing, a pendulum pivotably mounted to the housing, and a laser diode assembly disposed on the pendulum. A gimbal assembly is employed for pivotably mounting the pendulum to the housing. The gimbal assembly includes a frame connected to the housing, a first pair of bearings disposed on the frame, an axle extending through the first pair of bearings, a body disposed on the axle and pivotably supporting the pendulum, and a second pair of bearings disposed between the body and the pendulum. The first pair of bearings is disposed on one side of the second pair of bearings.
