LINCO polyurethane caster wheels provide an extremely durable, long lasting, and easy to sanitize solution for wheels. Made from extremely strong and corrosive resistant polyurethane, our polyurethane caster wheels are sure to withstand a multitude of abuse. Urethane caster wheels are best applied in medical, laboratory, and assisted living settings where an extremely sterile environment is required. Polyurethane wheels are an ideal solution to this type of environment as they can come with an all plastic bore making it difficult for microorganisms to live and to also easily sanitize. Our polyurethane caster wheels are also an ideal choice in a corrosive environment where rust can easily damage and cause a premature failure to a metal wheel.
