Wheel: Load Capacity 25-150 kg per caster

Q: What is the difference between a rigid caster and a swivel caster?

A rigid caster has a fixed wheel that only rolls forward and backward, while a swivel caster rotates 360 degrees, allowing omnidirectional movement. Swivel casters are common for furniture needing easy repositioning.

Q: How do I choose the right caster wheel material?

Select based on floor type and load: soft rubber or polyurethane for hard floors to prevent scratches; hard plastic or metal for heavy loads on rough surfaces; larger diameters for carpets or uneven floors.

Q: What load capacity do I need for furniture casters?

Calculate total furniture weight divided by the number of casters, then add a safety margin (e.g., 20-30%). For a 100 kg cabinet with 4 casters, choose casters rated at least 30-35 kg each.

Component Specifications

Definition

A furniture caster wheel is a specialized rolling component consisting of a wheel mounted on a fork and a swivel mechanism (often a ball bearing race) housed within a top plate. It is designed to be attached to the base of furniture legs or frames, allowing for omnidirectional movement with minimal effort. The assembly typically includes a stem or plate for mounting, a swivel joint for 360-degree rotation, and a wheel that contacts the floor surface. Modern variants may include braking mechanisms, load ratings, and floor-protective materials.

Working Principle

The caster operates on the principle of reducing friction through rolling motion and pivot rotation. The wheel converts sliding friction into rolling friction, while the swivel mechanism (using ball bearings or a kingpin) allows the fork and wheel to rotate freely around a vertical axis. This dual-axis movement enables the furniture to be pushed in any direction without needing to lift or drag it, distributing weight evenly and protecting floor surfaces.

Materials

Wheel: Polyurethane, rubber, nylon, thermoplastic elastomer (TPE), or soft tread rubber for floor protection; hard plastic or metal for industrial use. Fork: Zinc-plated steel, stainless steel, or reinforced plastic. Swivel mechanism: Steel ball bearings or bronze bushings. Top plate/stem: Steel, sometimes with zinc or chrome plating.

Engineering Analysis

Risks & Mitigation

Overloading causing wheel deformation or swivel failure
Incompatible wheel material damaging floors
Poor installation leading to instability or detachment
Wear over time reducing mobility or creating noise

FMEA Triads

Trigger: Exceeding load rating
Failure: Wheel flattening, bearing seizure, or fork bending
Mitigation: Use casters with appropriate load capacity; distribute weight evenly; consider heavy-duty models for high loads

Trigger: Abrasive debris accumulation
Failure: Swivel mechanism jamming, reduced rotation
Mitigation: Regular cleaning; use sealed bearing designs; avoid dirty environments

Trigger: Material fatigue or corrosion
Failure: Cracked wheel, rusted components, breakage
Mitigation: Select corrosion-resistant materials (e.g., stainless steel); inspect periodically; replace worn casters
