This wheel for furniture caster project is positioned as a nominal 4-inch black rubber swivel caster with a top plate and brake, based on the current product record and the main image. The exact wheel diameter, tread width, overall height, plate pattern, brake function, materials and rated load must be confirmed for the quoted model.
It is intended for B2B importers, furniture-hardware distributors, display-fixture builders and light-equipment manufacturers that need a model-matched replacement or OEM caster rather than an unverified generic size.
Specification review for a furniture or fixture caster
| Specification point | Current product direction | Confirmation required |
|---|---|---|
| Nominal wheel family | 4-inch / 100 mm sourcing reference from the existing record | Verify the actual outside diameter on the drawing or approved sample |
| Caster configuration | Swivel top-plate caster with a brake shown | Confirm whether the requirement is wheel brake, swivel lock or total lock |
| Mounting | Top-plate direction | Plate length and width, hole centres, hole diameter and installation clearance |
| Overall dimensions | Model-specific | Tread width, overall height and swivel-clearance envelope |
| Wheel and bracket materials | Black tread and metal bracket shown | Required tread, hub, bracket finish and operating environment |
| Rated load | Not assumed from the nominal wheel diameter | Loaded furniture/equipment weight, caster quantity, layout and duty cycle |
| OEM program | Model, marking and packaging review available | Sample or drawing, order quantity, label, carton and destination |
Why the brake and mounting drawing matter
A brake pedal visible in a product image does not by itself define what is locked. Some models stop wheel rotation, while others lock both the wheel and swivel action. State the required function and check pedal access on the complete furniture or fixture.
Likewise, two nominal 4-inch casters can use different plate sizes, hole patterns and overall heights. Send the existing top-plate drawing and the available swivel clearance before selecting a replacement.
Information that speeds up a B2B quotation
- Application photo and total loaded weight.
- Number and layout of casters on each unit.
- Wheel diameter, tread width and overall-height target.
- Top-plate size, bolt-hole centres and hole diameter.
- Required brake function, floor type, travel frequency and obstacles.
- Order quantity by model, marking, packaging and destination.
Commercial value for importers and furniture-hardware brands
- Fewer fitment complaints: the plate pattern, overall height and swivel clearance are approved before volume production.
- Clear brake specification: the quotation records the required locking function instead of relying on a generic “with brake” label.
- Repeat-order control: the model, drawing, label and packing can be tied to a customer SKU.
- Evidence-based load selection: any load rating belongs to the exact quoted assembly and agreed test method.
Typical applications
Furniture, display fixtures, service carts, cabinets and light mobile equipment where a top-plate swivel caster and accessible brake are required. Final suitability depends on the loaded unit, floor, speed, impacts and mounting strength.
For other rigid, swivel, stem-mounted or industrial options, see the OEM caster manufacturer page and the industrial caster collection. The industrial versus furniture caster guide explains the main selection differences.
Frequently asked questions
Is every nominal 4-inch caster interchangeable?
No. Wheel diameter, overall height, plate pattern, swivel clearance and brake layout can differ. Approve the drawing or sample for the exact model.
Does the brake lock both the wheel and swivel?
That must be confirmed by model. State whether the project needs a wheel brake, directional lock or total lock.
How is rated load confirmed?
It is confirmed for the complete caster assembly and an agreed test basis, using the equipment weight, caster layout and duty conditions supplied by the buyer.
Can you match an existing furniture caster?
Yes, subject to review. Send the caster sample or a dimensioned drawing, clear mounting photos and the required quantity.
