Loading Diagrams with Related Spring Stresses注意此时轴承的安装方向建议轴承安装方法由微航动力翻译Suggested Methods for Installing C-Flex BearingsRadial Loading: Spring in Tension (Lt)径向受载（拉缩时）The following examples are a few of the possible methods for installing standard C-Flex bearings. Other techniques may provide satisfactory results. Special options, such as flanged or drilled and tapped sleeves may be provided upon request. Please contact C-Flex with questions or a review of mounting requirements. Set ScrewOne or more properly sized cup point set screws may be used to clamp bearing in place. Hole size should be .0005” to .0010” larger than bearing.

推荐用螺丝夹持夹紧Clamp ScrewClamping screw applies suitable pressure to retain bearing in place. Hole size should be .0005” to .0010” larger than bearing.Radial Loading: Spring in Compression (Lc)径向载荷孔径公差：+0.01~+0.03mmRadial or Axial PinsPins may be pressed into holes drilled through the mounting bracket and the bearing sleeve. Care must be exercised to orient the bearing properly so the springs are not damaged. Hole size should be .0005” to .0010” larger than bearing.

Axial Loading: Springs in Shear径向载荷Locator Flats

Locator flats with cup point set screws may be used to orient and securely clamp bearing in place. Hole size should be .0005” to .0010” larger than bearing.
