A moving element for moving on a track of a conveyor system, the moving element including: a first set of bearings shaped to match with a first shaped guide rail; a second set of bearings configured to abut against a second guide rail; and a body supporting the first and the second bearing, wherein the body is shaped to allow the first bearing to at least partially overlap the body of an adjacent moving element.
1. A linear motor conveyor system comprising:
a track comprising:
at least one guide rail; and
a plurality of moving elements, each moving element comprising:
a body;
at least one bearing supported by the body and configured to move along the at least one guide rail; and
a bearing suspension system configured to provide suspension to the at least one bearing, wherein the bearing suspension system comprises a vertical rotary axis configured to allow the at least one bearing to pivot in relation to the at least one guide rail.
2. A linear motor conveyor system according to claim 1 , wherein the at least one bearing comprises two bearings mounted to the moving element such that the plurality of moving elements overlap along the direction of the track providing a reduced tooling pitch between the moving elements.
3. A linear motor conveyor system according to claim 2 , wherein the guide rail comprises a plurality of guide rails and the two bearings are configured such that different bearings can run on different guide rails to allow the bearings and moving elements to overlap.

a second set of bearings configured to abut against the second guide rail; and
the bearing suspension system is configured to provide a suspension to the second set of bearings.
5. A linear motor conveyor system according to claim 1 , wherein the bearing suspension system further comprises a thinned body of the moving element configured to bias the at least one bearing towards the at least one guide rail.
6. A linear motor conveyor system according to claim 1 , wherein the bearing suspension system further comprises the at least one bearing having a hollow area in the interior of the bearing.
7. A linear motor conveyor system according to claim 1 , wherein the bearing suspension system further comprises an arm, wherein the arm is configured to support the at least one bearing and bias the at least one bearing toward the at least one guide rail.
8. A moving element for moving on a track of a linear motor conveyor system, the moving element comprising:
at least one magnet for interacting with a linear motor of the track to move the moving element along at least one guide rail using electromagnetic forces;
at least one bearing;
a body supporting the at least one bearing; and
a bearing suspension system configured to provide a suspension to the at least one bearing, wherein the bearing suspension system comprises a vertical rotary axis configured to allow the at least one bearing to pivot in relation to the at least one guide rail.
9. A moving element according to claim 8 , wherein the at least one bearing comprises:
a first set of bearings shaped to match with and abut against a first shaped guide rail of the at least one guide rail;
a second set of bearings configured to abut against a second guide rail of the at least one guide rail; and
a body supporting the first set of bearings and the second set of bearings, wherein the body is shaped to allow at least one of the first set of bearings and the second set of bearings to at least partially overlap the body of an adjacent moving element.
10. A moving element according to claim 9 , wherein the bearing suspension system is configured to provide a suspension to the second set of bearings.
11. A moving element according to claim 8 , wherein the bearing suspension system further comprises a thinned body of the moving element configured to bias the at least one bearing toward the second guide rail.
