I have plastic trays that had bearings in them . Over time will the oil in the trays cause any chemical reaction ?
complicated thing. seek with google. it could help!
If bearing oil is petroleum-based, then yes eventually it will eat the plastic.
It depends on the oil and the plastic. Plastic and synthetics have very different tolerances to different oil types. Some plastic additives can make them much more tolerable to some chemicals. Temperature also can make a difference. If you know the type of oil and plastic, industrial supply catalogs list which ones are compatible.
