重庆升降机轴承套圈承受的负荷类组不同，选择轴承配合的松紧程度也应不间。承受局部负荷的套圈，局部滚道始终受力，磨损集中，其配合应选松些。目的是让固定式升降平台套圈在振动、冲击和，攘力矩的带动下级转位，以充分利用全部滚道并使磨拐均匀。从而延长轴承的寿命，但配合也不能过松，否剧会引起套圈在相配件上淆动而使结合面磨扭。对于旋转精度有要求的场合，用不允许套圈转位，以免影响升降平台支承度。
Wenzhou lifting platform load on the bearing rings of different clusters, select the tightness of fit of the bearing should be no room. Ferrule to withstand partial load, force local raceway always wear concentrated loose some of its tie to be elected. The purpose is to allow the lifting platform rings fixed in vibration, shock and, Rang moment, driven lower translocation to take advantage of all races and mill turn evenly. Thus extending bearing life, but with not too loose, not drama will cause confusion ferrule fittings move on with leaving the joint surface grinding twist. For rotation accuracy requirements of the occasion, with ferrule indexing is not allowed, so as not to affect the degree of Wenzhou lifting platform support.
　
升降机承受循环负荷的套目，滚道各点循环受力，磨损均匀，其配合应选择紧些。因为固定式升降平台套圈与轴颈或外壳孔之间工作时不允许产生相对滑动以免结合面磨损，并且要求在全日周上具有毯固的支承，以保证负荷能最佳分布，从而充分发挥轴承的承级力。
Wenzhou lifting platform subjected to cyclic loading sleeve mesh points race cycling stress, wear a uniform, which should be selected with some tight. Because fixed lifting platform between the ring and the journal work or housing hole allowed to combine in order to avoid relative sliding surface wear, and requires a solid blanket support in all-day week, in order to ensure optimal load can be distributed, to maximize Cheng level force bearing.
