a second spring extending inward from the perimeter of the housing, wherein the second spring is configured to bias a second bearing of the plurality of bearings towards a second portion of the track, wherein the housing defines a recess disposed at least partially between the first spring and the second spring; and
a dampening element at least partially disposed within the recess, wherein the dampening element is configured to dampen movement of the first spring.
2. The bearing assembly of claim 1 , comprising a frame defining a window, wherein the housing is disposed in the window of the frame.
3. The bearing assembly of claim 2 , wherein the housing is removably coupled to the frame.
4. The bearing assembly of claim 1 , wherein the dampening element is made of a plastic material, a rubber material, a silicone material, a polymer material, or any combination thereof.
5. The bearing assembly of claim 1 , wherein the dampening element includes a color, a geometry, a marking, or any combination thereof indicative of a function of the dampening element.
6. The bearing assembly of claim 1 , wherein:
the first spring comprises a first arm;
the second spring comprises a second arm;
the first bearing of the plurality of bearings is coupled to the first arm at a first end of the first arm; and
the second bearing of the plurality of bearings is coupled to the second arm.
7. The bearing assembly of claim 6 , wherein a third bearing of the plurality of bearings is coupled to the first arm at a second end of the first arm, and wherein the first arm is configured to bias the third bearing of the plurality of bearings towards a third portion of the track.
8. The bearing assembly of claim 6 , comprising a third spring including a third arm, wherein the third arm is configured to bias a third bearing of the plurality of bearings towards a third portion of the track.
9. The bearing assembly of claim 8 , comprising:
a fourth spring including a fourth arm, wherein the fourth arm is configured to bias a fourth bearing of the plurality of bearings towards a fourth portion of the track; and
a second recess disposed at least partially between the third arm and the fourth arm.
10. The bearing assembly of claim 9 , comprising a second dampening element at least partially disposed in the second recess, wherein the second dampening element is configured to dampen movement of the third arm and the fourth arm.
11. The bearing assembly of claim 1 , wherein the dampening element is removably coupled to the housing.
12. A bearing assembly for a mover of a linear motor system, comprising:
a plurality of bearings configured to interface with a track of the linear motor system;
a housing configured to retain the plurality of bearings, the housing comprising:
a first spring configured to bias a first bearing of the plurality of bearings toward a first portion of the track;
a second spring configured to bias a second bearing of the plurality of bearings toward a second portion of the track;
a cross-member disposed between the first spring and the second spring, wherein the housing defines a first recess disposed at least partially between the cross-member and the first spring; and
a dampening element at least partially disposed in the first recess, wherein the dampening element is configured to dampen movement of the first spring.
13. The bearing assembly of claim 12 , wherein the first spring comprises a flange, the flange including a flange head configured to retain the first bearing.
14. The bearing assembly of claim 12 , wherein the housing comprises a second recess disposed at least partially between the cross-member and the second spring.
15. The bearing assembly of claim 12 , wherein the dampening element is fixed to the housing.
16. A mover of a linear motor system, comprising:
a body defining a cavity;
a bearing assembly disposed within the cavity, wherein the bearing assembly comprises:
a plurality of bearings configured to interface with a track of the linear motor system;
a housing configured to retain the plurality of bearings, the housing comprising:
a first spring configured to bias a first bearing of the plurality of bearings towards a first portion of the track;
wherein the housing defines a recess; and
a dampening element at least partially disposed within the recess, wherein the dampening element is configured to dampen movement of the first spring.
17. The mover of claim 16 , wherein the housing comprises a second spring configured to bias a second bearing of the plurality of bearings towards a second portion of the track.
18. The mover of claim 17 , wherein the dampening element is configured to dampen movement of the second spring.
19. The mover of claim 16 , wherein the first spring comprises a first arm including a head configured to retain the first bearing.
20. The mover of claim 16 , wherein the bearing assembly is removably coupled to the body.
