INDUSTRY COMPONENT

Swivel Fork

Swivel fork is the rotating component in furniture casters that enables 360-degree directional movement.

Component Specifications

Definition
A swivel fork is the structural component of a furniture caster assembly that connects the wheel to the mounting plate or stem. It contains a swivel bearing mechanism that allows the wheel to rotate freely around a vertical axis while supporting the load. This component is essential for providing omnidirectional mobility to furniture pieces, enabling smooth movement in any direction without requiring the entire piece to be turned.
Working Principle
The swivel fork operates on a bearing-based rotation principle. It contains a raceway with ball bearings between the fork's upper mounting section and lower wheel axle section. When lateral force is applied to the furniture, the bearings allow the fork to rotate around the vertical axis while maintaining load capacity. This separates the wheel's rolling motion (horizontal axis) from the caster's directional change (vertical axis), enabling true omnidirectional movement.
Materials
Typically made from stamped or forged steel (SAE 1010-1020), zinc alloy (Zamak), or engineered plastics (polyamide, polypropylene). High-end versions may use stainless steel (304/316) or aluminum alloys for corrosion resistance. Bearing components are usually carbon steel or stainless steel balls with brass or polymer retainers.

Frequently Asked Questions

What is the difference between a swivel fork and a rigid fork in casters?

A swivel fork allows 360-degree rotation for omnidirectional movement, while a rigid fork is fixed and only allows forward/backward movement. Swivel forks contain bearing mechanisms that rigid forks lack.

How do I maintain a swivel fork mechanism?

Regular cleaning to remove debris, periodic lubrication of bearing surfaces (if not sealed), and inspection for wear in the raceway or bearing components. Sealed bearings typically require no maintenance.

Can swivel forks be replaced separately from the entire caster?

Yes, most quality casters allow swivel fork replacement. However, compatibility with the wheel axle and mounting system must be verified. Some budget casters have integrated designs requiring full unit replacement.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
