Polyolefin caster wheels offer exceptional durability on smooth concrete, tile, and sealed floors. The hard plastic compound resists most chemicals and handles static loads without flat-spotting. Available in 2" to 8" diameters, rated 100 to 500 lbs per caster.
Polyolefin performs best on smooth concrete, tile, epoxy, and sealed wood.
The hard plastic compound rolls cleanly without leaving marks or residue. On rough concrete or outdoor surfaces, a softer rubber or pneumatic wheel is a better choice — polyolefin will bounce on expansion joints and generate noise on rough surfaces.
For smooth indoor floors, yes — polyolefin rolls easier and lasts longer under heavy static loads.
Rubber wheels cushion and grip but flat-spot under sustained weight. Polyolefin holds its shape and has lower rolling resistance. For applications with constant movement on smooth floors carrying 100–500 lbs per caster, polyolefin is the preferred specification.
Standard polyolefin is gray or black and can leave light marks on light-colored floors.
Non-marking (white or gray compound) polyolefin wheels are available for clean rooms, hospitals, and showrooms where floor appearance matters. Always specify "non-marking" if floor condition is a concern.
Yes — polyolefin resists most mild acids, bases, and cleaning solvents.
The compound is impervious to most industrial cleaners and dilute chemicals. For concentrated acids, strong solvents, or oils, verify chemical compatibility for your specific application — nylon may be a better choice for extreme chemical environments.
Per-caster capacity = total load ÷ number of casters × 1.25 safety factor. For static storage applications, increase safety factor to 1.5 since polyolefin does not creep under load like rubber, but impact stress from drops or bumps can exceed rated dynamic load.
