A roller assembly for a sliding vehicle door configured for moving in relation to a track member of a vehicle, the roller assembly comprising a bracket structure comprising a first inner horizontal guide roller and a second inner horizontal guide roller arranged to interact with an inner vertical surface of the track member, wherein the bracket structure further comprises at least a first vertical guide roller and a second vertical guide roller arranged to interact with a first inner horizontal surface of the track member, a resiliently arranged rotatable member arranged to interact with a second inner horizontal surface of the track member and at least one outer horizontal guide roller arranged to interact with an outer vertical surface of the track member.
2. The roller assembly according to claim 1 , wherein the resiliently arranged rotatable member is arranged between the first vertical guide roller and the second vertical guide roller on the bracket structure, wherein the resiliently arranged rotatable member is essentially aligned with a vertical plane of rotation of the first vertical guide roller and the second vertical guide roller.
3. The roller assembly according to claim 2 , wherein a first hub of the first vertical guide roller, a second hub of the second vertical guide roller and a contacting point of the resiliently arranged rotatable member are arranged in a triangular relationship essentially in the vertical plane of rotation of the first vertical guide roller and the second vertical guide roller.
4. The roller assembly according to claim 1 , wherein the resiliently arranged rotatable member comprises a ball bearing arranged in a spring-loaded seat attached to the bracket structure.
5. The roller assembly according to claim 1 , wherein the at least one outer horizontal guide roller comprises a first outer horizontal guide roller and a second outer horizontal guide roller that are each arranged to interact with the outer vertical surface of the track member.
6. The roller assembly according to claim 1 , wherein the at least one outer horizontal guide roller is arranged in an outer horizontal plane of rotation separated from an inner horizontal plane of rotation in which the first inner horizontal guide roller and the second inner horizontal guide roller are arranged.
7. The roller assembly according to claim 1 , wherein the at least one outer horizontal guide roller is arranged on an outer horizontal guide roller bracket arranged to be attached to the bracket structure.
8. A vehicle door comprising the roller assembly according to claim 1 , wherein the roller assembly is rotatably attached to a roller assembly arm.
9. A vehicle body comprising the roller assembly according to claim 1 , wherein the roller assembly is rotatably attached to a roller assembly arm.
