Applications

Hospitality service carts and housekeeping trolleys Retail display racks and mobile shelving units Light manufacturing assembly line equipment Medical facility transport carts and diagnostic machinery stands Office furniture mobility solutions and audio-visual equipment stands Food service utility carts requiring hygienic and quiet movement Product Performance and Installation The 4-inch wheel diameter provides an optimal balance between maneuverability and obstacle clearance, allowing operators to navigate minor floor imperfections with ease. The rubber compound is formulated to resist wear while maintaining flexibility, which extends the service life of the caster under repeated use. Installation is straightforward due to the standardized M12 stem design, which threads directly into compatible receiving sockets or mounting plates. The 25mm stem length offers sufficient engagement depth to prevent loosening during dynamic loads. Users should verify that the total number of casters multiplied by the 90 lbs individual rating exceeds the total weight of the loaded equipment to ensure safe operation. These casters are particularly well-suited for facilities where floor preservation is critical, as the non-marking rubber tread prevents black streaks and surface damage common with harder wheel materials.
