TN=塑料保险架，允许运转温度：120℃连续地，150℃临时地，180℃短时地。1)对于脂润滑，允许值为表列数值的60%。
有档圈，无润滑油孔和槽，如需要油孔和槽时，需在轴承代号上增加ASR1。
TN= plastic cage, prescribed working temperatures, 120℃ in succession，temporarily when it is 150℃, quick when it is 180℃.
1) prescribed limiting speed of lubrication is 60% based on the table, with rib, without lubrication hole and groove, it needs to add ASR1 on the bearing designation with lubrication hole and groove
