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 extending inward from a perimeter of the housing, wherein the first spring is configured to bias a first bearing of the plurality of bearings toward a first portion of the track;
- 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.
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.
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.
