SUMITOMO Swing Motor Seal Kit Precautions for storage Please pay attention to the following matters when storing seals: 1) Do not open the package when not needed. Otherwise, the seals may get "dusted", or "scratched". 2) Please store in a place with low humidity and avoid direct sunlight. Ultraviolet rays and moisture accelerate the deterioration of rubber materials and dimensional changes and deterioration of resin materials. 3) When storing the opened product, please be careful not to allow foreign matter to adhere or mix in, and repackage it as it is as much as possible. Nylon, in particular, may change in size due to moisture absorption, so please keep it sealed. 4) Do not place it near high temperature heat sources such as boilers and stoves. Rubber materials deteriorate rapidly due to heat. 5) Do not place near items such as motors that are prone to ozone generation. 6) Do not hang with nails, iron wires, ropes, etc., which will cause deformation of the seal or injury to the front end of the lip. 7) Discoloration or white powder on the surface (blooming phenomenon) may occur during storage, but these conditions will not affect the performance. 8) The PTFE slip ring of the combined seal is easy to be damaged due to drop shock or external hard force, etc., please pay attention when using it
