INNOVATION IN MOTION: Designed by the creative engineers at OMCO SUMO – a leading US ball bearing manufacturer since 1964. Backed by a 5-year manufacturer's warranty.
SAFE ON ALL FLOORS: Non-marring, medium durometer urethane tires are suitable for hard & soft flooring. Hygienic twin-wheel hubless design (no axle or blind opening to hold debris).
NEAR UNIVERSAL FIT: Standard 11mm friction sleeve stem mount fits most office and gaming chair sockets (not IKEA). Quick and easy installation in seconds.
EXPONENTIALLY STRONGER: Estimated load capacity of 200 lbs. per caster (5 casters = 1000 lbs.) – 2.5 times the load rating of typical replacement chair casters. Certified compliant with BIFMA X5.1 durability standards for office chairs.
BEARINGS MAKE ALL THE DIFFERENCE: Utilizes two large high-precision chrome steel radial ball bearings per caster.
