Avoiding Rubber Component Design Problems

The unique aspects of rubber product design require care to prevent unforeseen problems in the performance or manufacture of a part. The following is a list of common problems sometimes encountered when designing rubber parts, and some suggestions for avoiding them.

  1. Attempting to compress rubber (or overfilling the groove)
  2. Designing a rubber part which cannot be manufactured
  3. Not providing installation tools and/or employee training
  4. Failing to consider all possible chemicals/processes which may contact the rubber component
  5. Not providing sufficient lubrication for a seal or other dynamic rubber part
  6. Not allowing enough room for a seal or rubber part
  7. Using too small a seal or rubber part
  8. Using a seal as a bearing
  9. Not considering rubber thermal effects
  10. Not accounting for seal friction and power loss
