A useful medical caster RFQ gives suppliers enough information to propose a defined configuration, rather than a wheel that simply looks similar. For hospital bed and medical trolley projects, the drawing, operating conditions and acceptance checks matter as much as the unit price. Use the following checklist before requesting samples or a production quotation.
Start with the equipment and operating environment
State whether the caster is intended for a hospital bed, treatment trolley, equipment stand or another application. Describe the route: room floors, corridors, lift entrances, joints and thresholds. Include the maximum loaded equipment mass and explain how the equipment will move and park. A caster selected for occasional repositioning may face different conditions from one used repeatedly along a busy route.
Build a specification sheet suppliers can answer
| RFQ field | Information to provide |
|---|---|
| Equipment load | Empty mass, maximum payload, load distribution and number of supporting casters |
| Dimensions | Wheel diameter, overall height, wheel width and space available for swivelling |
| Mounting | Dimensioned stem or plate drawing, thread details, fasteners and tolerances |
| Brake function | Free swivel, wheel brake, total lock, directional lock or a central locking interface |
| Environment | Floor type, thresholds, operating temperature and cleaning procedure |
| Order requirements | Sample quantity, expected annual demand, delivery location and required documents |
Ask how the load rating applies to your project
Do not compare load figures without checking their conditions. Ask whether a quoted rating is static or dynamic and request the applicable test conditions. Give the supplier the complete operating scenario, including uneven support and threshold crossings, so the proposed configuration can be assessed for your equipment. A component rating alone does not establish the capacity of a finished hospital bed or trolley.
Define the brake and mounting interface
Brake terminology can vary between catalogues. Describe the required behaviour in each pedal position and request a drawing. For central locking systems, include the linkage arrangement and the equipment manufacturer’s interface requirements. DYU’s CC series central lock caster range is a starting point for a configuration discussion; confirm the exact model before ordering.
Compare quotations on the same basis
Ask each supplier to identify its offered model, deviations from the drawing, sample lead time, production lead time, packing and quotation validity. Keep freight, tooling and testing costs visible. Request evidence for any certification or performance claim that is important to your project. Treat a broad claim such as “medical grade” as a question to resolve, rather than a measurable acceptance criterion.
Agree on sample acceptance before bulk purchasing
Record what the sample must demonstrate on the actual equipment: fit, clearance, movement and the specified brake functions. Use representative loads and routes under an approved evaluation procedure. Keep the accepted drawing and sample identification with the purchase record so future orders refer to the same configuration.
Browse DYU’s DS series double wheel casters and single wheel caster range, then send your RFQ and mounting drawing. A clear specification helps our team discuss suitable options and identify details that still need confirmation.
