Technical specifications for the Suemisi Caster set describe a mechanical retrofit solution for 11mm stem chair bases. The architecture utilizes a dual ball-bearing system to provide 360-degree swivel rotation. Material analysis confirms the wheels are constructed with a soft polyurethane (PU) layer over a rigid nylon core, which functions to reduce the grinding effect on sensitive flooring surfaces.
The stem dimensions are 11mm x 22mm, which is incompatible with IKEA-proprietary 10mm sockets. Performance data indicates that while the PU layer provides surface protection, it is susceptible to the ingestion of hair and debris into the axle, which can impact rotational fidelity. Furthermore, the non-locking design may allow for lateral drift on flooring surfaces that are not perfectly level.
Load capacity is distributed across the set, and the analog nature of the hardware necessitates periodic lubrication of the stem and swivel race with lithium grease to prevent mechanical seizure.
These swivel caster wheels serve as a silent-operation alternative to standard-issue plastic casters for home office environments.
This hardware is classified as custom chair components designed for surface-specific mobility optimization.
