Technical specifications for the Omyoffice Heavy Duty Wheels indicate a mechanical-grade upgrade for standard office seating, utilizing a rollerblade-style polyurethane (PU) design. Material analysis confirms the use of high-grade transparent PU, which functions as a vibration isolator between the chair frame and hard flooring surfaces to facilitate acoustic dampening and surface preservation.
Structural integrity is maintained via a stamped steel bracket construction and a universal 11mm x 22mm stem. This architecture ensures compatibility with approximately 95% of ergonomic chair frames, with the notable exception of IKEA-proprietary sockets. Performance metrics demonstrate that the precision ball-bearing races allow for low-torque movement, although longitudinal data suggests these internal components are susceptible to debris ingress over an operational period exceeding 18 months.
Installation of these units results in an increased chair height of approximately 1 to 1.5 inches compared to standard twin-wheel nylon casters. This dimensional change requires verification of armrest clearance for fixed-height workstation surfaces to maintain ergonomic alignment.
Operational data confirms that the high-efficiency bearings can result in lateral drift on non-level flooring surfaces, requiring user awareness of the "zero-effort" movement characteristic.
Performance metrics indicate that these heavy duty wheels serve as a high-clearance alternative for users requiring superior floor protection without the use of secondary plastic mats.
This mechanical component is classified within the broader ecosystem of custom chair components, which provide the structural foundation for specialized ergonomic hardware.
