1、轴·轴承箱用止动环-滚针轴承用为防止滚针轴承的套圈和带保持架滚针套的轴向移动，须采取定位措施。由于滚针轴承的剖面高度较小，因之往往不能使用一般的止动环。此时，可采用以下特别设计的WR型及BR型滚针轴承专用止动环。WR型轴用止动环及BR型轴承箱用止动环采用硬质钢线材制成，表面进行了化学处理。WR型及BR型滚针轴承止动环难于分解。故此，在需要分解和重新组装的场所，可根据滚针轴承的剖面高度，研究能否采用一般的C型（JISB2804）或同心式C型（JISB2806）止动环。允许转速所谓允许转速，是指WR型轴用止动环在轴旋

2、转时的离心力作用下，切口张开，有可能产生松动时的转速。使用时，不得超过尺寸表中所规定的允许转速。另外，为对保持架做轴向引导，推荐在止动环与保持架之间使用垫圈。但在线速度小的情况下，可以不用垫圈。轴用止动环型号尺寸及允许差mmd1d3bsd2最大±0.06下偏差允许转速rpmWR4WR5WR6WR7WR8WR9WR10WR11WR12WR13WR14WR15WR16WR17WR18WR19WR20WR21WR22WR2345678910111213141516171819202122233.74.75.66.57.
