Despite their small list of avoidances, phenolic caster wheels boast the same strength as metal wheels and can insure the safe transport of any weight baring load across the oiliest of surfaces. They also serve as an excellent caster wheel for storage carts in oily greasy environments as they can withstand any spill or spray of such materials with very little damage to the wheel itself. LINCO also offers high temp phenolic caster wheels if the object that they are affixed to will often be carrying a high temperature cargo that could possibly melt or damage a lower temperature grade wheel. Our phenolic caster wheels come in a wide range of colors, bores, and sizes to meet any project or repair need. LINCO phenolic caster wheels are an excellent choice for a slip resistant wheel so long as the surface that it is being pushed on is a hard-flat surface.
