Technical Definition A furniture caster is a wheeled component mounted to the base of furniture items to enable easy movement and repositioning. ## 2. Engineering Reasoning & Causal Matrix > **Operational Intelligence**: Designed for **50-150 N vertical load per caster, 0-0.5 m/s rolling speed, -10°C to 60°C ambient temperature**. Failure boundary: **Ball bearing seizure at 180 N static load, raceway plastic deformation at 200 N, swivel joint galling at 10⁶ cycles under 100 N radial load**, Mechanism: **Hertzian contact stress exceeding 1.5 GPa at ball-raceway interface causes subsurface fatigue spalling; adhesive wear at swivel pin-bushing interface due to boundary lubrication failure below 0.1 μm oil film thickness**. ### 2.2 FMEA (Failure Mode & Effects Analysis) | Event Trigger | Severity | Failure Mode | Mitigation Strategy | | :--- | :--- | :--- | :--- | | Abrasive particle ingress >15 μm diameter into ball bearing clearance | 8 | Raceway brinelling and torque increase >0.8 N·m | Labyrinth seal with 0.05 mm radial clearance and IP54 rating | | Repeated 90° directional changes under >120 N load at <1 second intervals | 8 | Swivel post fatigue fracture at thread root stress concentration factor Kt=3.2 | Cold-forged M8 swivel post with rolled threads and 600 MPa yield strength | ## 3.

Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the typical load capacity range for furniture casters? **A**: According to the directory reference, the load capacity ranges from 50 to 300 kg, as per ISO 22883. However, the actual capacity depends on the specific model and application. Always verify with the manufacturer. ### Q: What wheel materials are available? **A**: Common wheel materials include polyurethane (PU), polypropylene (PP), polyamide (PA), and rubber. Each offers different properties in terms of floor protection, noise, and durability. The specific material should be chosen based on the intended use. ### Q: How does the swivel mechanism work? **A**: The swivel mechanism consists of a kingpin and bearing assembly that allows the fork to rotate 360 degrees around a vertical axis. This enables the caster to change direction easily. The swivel radius, which is the distance from the kingpin center to the wheel center, affects the turning footprint. ### Q: What brake types are available? **A**: Brake types can be none, side, or total. A side brake typically locks the wheel, while a total brake locks both the wheel and the swivel. The choice depends on the application's need for stability and safety. ## 6.
