Tha giùlan ball sreath dùbailte freagarrach airson luchdan radial meadhanach agus luchdan beaga axial gach taobh.Tha an dealbhadh agus an gnìomh aca coltach ri paidhir de ghiùlan ball aon-sreath.Tha na bearings sin air an cleachdadh ann an tagraidhean far nach eil comas luchdan giùlan aon-sreath gu leòr.Tha an aon trast-thomhas a-muigh agus trast-thomhas tollaidh aig giùlan ball sreath dùbailte ri giùlan aon-sreath, ach tha iad nas fharsainge agus tha comas luchdan gu math nas àirde na giùlan singilte. - sreath ball bearings den t-sreath 62 agus 63.
