Blind installation of O-Rings and Backup Rings causes Pinching and cut. Help !!
Post Body
Hi All,
For one of our assembly we are installing the following combination :
- Backup Ring (split kind with scarf cut)
- O-Ring
- Backup Ring (split kind with scarf cut)
Over this, there is a mandrel that slides on top (so this basically becomes a blind installation) However sometimes in very few cases, the mandrel forces the cut backup ring to squeeze onto the O-Ring and cuts the O-Ring. Is there anything that can be done to reduce such kind of problems ?
Thanks !!
