Product Specifications

Technical details and manufacturing context for Furniture Caster

Definition
A furniture caster is a wheeled component mounted to the base of furniture items to enable easy movement and repositioning. It consists of a wheel mounted within a swiveling fork assembly that allows 360-degree rotation. These components are essential for office chairs, mobile cabinets, hospital beds, and other furniture requiring frequent relocation. They are manufactured as standalone B2B parts for furniture assembly lines.

Typical construction includes a polyurethane wheel, a steel fork, ball bearings, and a zinc alloy housing. The wheel material can vary among PU, PP, PA, or rubber, affecting durability, floor protection, and noise. The bracket material is usually SPCC zinc-plated steel, with stainless steel available for corrosion resistance.

Key parameters to verify for a specific application include load capacity (50–300 kg per ISO 22883), wheel diameter (40–100 mm), total height (50–150 mm), swivel radius (60–120 mm), mounting plate size (60×60 to 100×100 mm), operating temperature (-20 to 60 °C), swivel resistance (5–15 N), rolling resistance (10–30 N), and noise level (≤50 dB(A) at 1 m). Brake types may be none, side, or total.

These values are reference ranges; actual performance depends on the specific model and application. Always confirm model-specific specifications and compliance with relevant standards with the legal manufacturer or supplier before procurement.
Working Principle
The caster operates on two independent movements: the wheel rotates around its axle for linear motion, while the swivel mechanism, typically a kingpin and bearing assembly, allows the fork to rotate 360° around a vertical axis. This combination enables the furniture to be pushed in any direction without lifting. The swivel radius, the horizontal distance from the kingpin center to the wheel center, determines the turning footprint. Lower swivel resistance (5–15 N) makes directional changes easier, while rolling resistance (10–30 N) affects the force needed to keep the caster moving. The load is transferred through the housing, fork, and bearings to the wheel. Proper selection of wheel material and diameter influences floor protection and noise. Brake mechanisms, when present, lock the wheel or swivel to prevent movement.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Bearing seizure or excessive wear
Cause: Accumulation of dust, hair, and debris in the bearing mechanism, combined with lack of lubrication, leading to increased friction, overheating, and eventual binding or catastrophic failure of the rolling elements.
Wheel tread degradation or delamination
Cause: Chemical exposure (e.g., harsh cleaners, solvents), UV radiation, or abrasive contact with rough flooring surfaces, resulting in cracking, chunking, or loss of material that compromises rolling efficiency and floor protection.
Maintenance Indicators
  • Audible grinding, squeaking, or irregular clicking noises during movement, indicating bearing contamination, lack of lubrication, or internal component damage.
  • Visible wobbling, uneven rolling, or erratic directional tracking of the caster, suggesting worn or damaged bearings, bent axles, or uneven tread wear.
Engineering Tips
  • Implement a regular cleaning and lubrication schedule: Use compressed air or a soft brush to remove debris from the wheel and bearing area, then apply a light, non-greasy lubricant (e.g., silicone-based) to the axle and bearing surfaces to reduce friction and prevent corrosion.
  • Match caster material to the operating environment: Select wheels with tread materials (e.g., polyurethane for durability, rubber for floor protection) and bearing types (e.g., sealed ball bearings for high-load applications) suited to the specific flooring, load capacity, and exposure conditions to minimize wear and chemical degradation.

Frequently Asked Questions

What is the typical load capacity range for furniture casters?

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.

What wheel materials are available?

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.

How does the swivel mechanism work?

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.

What brake types are available?

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.
