The MySit 2-inch Locking Caster is a mechanical component engineered for static-heavy environments. Technical documentation indicates a dual-bearing swivel race that facilitates 360-degree rotation under vertical compression. The contact surface consists of non-marring soft polyurethane, which functions as a vibration dampener to reduce acoustic resonance in high-fidelity environments.
Mechanical locking is achieved via a friction-lock "toe-press" lever system. Standardized testing protocols show that the 2-inch diameter provides higher rolling resistance compared to 3-inch alternatives, which optimizes stability on hard surfaces but may impede movement on high-pile textiles. The stem dimensions are specified as 7/16 inches by 7/8 inches (11mm x 22mm), conforming to universal standards for non-IKEA furniture.
Material analysis identifies the chassis as zinc-plated steel. While providing structural rigidity, this material is subject to oxidation in high-humidity environments. Additionally, the friction brake is designed to inhibit wheel rotation only; it does not prevent the swivel axis from movement.
Integrating caster wheels with brakes is recommended for tasks such as sim-racing where a fixed lateral position is a technical requirement.
These units represent a critical interface within the custom chair components category, offering specific mechanical constraints for controlled movement.
