What size casters do I need?

First calculate the total maximum weight and add a 33% safety buffer. Divide the result by the number of casters to find the required load capacity per caster. Then, choose a wheel diameter large enough to handle the floor type and obstacles, and measure your current mounting dimensions if replacing casters.

AI-Powered supplier vetting

SummaryThe supplier is identified as a caster-products company with an integrated R&D, production, and sales system. It offers broad customization and ODM services and has provided OEM services for well-known brands. However, its service-management documentation is incomplete: complaint-handling procedures and records are absent, and corrective-action records are not documented. It has no overseas warehouses, showrooms, agents, branches, or offline trade-show participation, and reports zero countries with overseas services. No certification information, production metrics, or customer case details are provided. R&D activity appears limited recently because no new products were reported in the past year, although the supplier states that it invests in R&D and has flexible design capabilities. Financial information is present only as coded values and cannot support a meaningful credibility assessment.

Supplier typeThe supplier is described as a caster-products company with a stated integrated R&D, production, and sales system. Its registered and physical addresses are both in Zaoqiang, Hengshui City, Hebei Province, China, supporting classification as a manufacturer rather than an overseas service provider.

After-Sales capabilityThe supplier has relevant service records and a partial approved-supplier list, but lacks written customer-complaint procedures and records; its corrective and preventive action mechanism has a procedure but no written records. It also has no overseas warehouse, showroom, agent, branch, or offline trade-show capability, although it reports lead times within 15 working days and accepts several service quotation and payment terms.

Production capacityThe company description states that the supplier has established an integrated R&D, production, and sales system for caster products and solutions. No capacity, equipment, output, quality-performance, or delivery-capacity metrics are provided, so the strength of production capability cannot be fully assessed.

Customization capabilityThe supplier explicitly offers customization from samples and designs, minor and flexible customization, full customization, and ODM services. It also reports OEM service for well-known brands, providing direct evidence of broad customization and contract-manufacturing capability.

Product Q&A

Q:What is a caster?

A caster is an undriven wheel that is designed to be attached to the bottom of a larger object to enable that object to be moved. Casters are used in numerous applications, including shopping carts, office chairs, toy wagons, hospital beds, and material handling equipment.

Q:What is the warranty period for your products?

18 months from the date of manufacture. Each product is clearly marked with the manufacturing date.

Q:Is it better to have 4 swivel casters or 2?

4 Rotating Casters: Best for environments requiring maximum maneuverability. 2 Fixed and 2 Rotating Casters: Ideal for heavy loads, straight-line movement, and stability.

Q:What is the weight limit for a caster?

Light Duty Casters: Ideal for loads up to 500 lbs, these casters are perfect for light equipment and everyday office use. Medium Duty Casters: With a capacity of up to 2000 lbs, these casters are suited for heavier equipment in industrial settings.

Q:Can I get some samples?

Yes, samples are available at any time. We charge a sample fee and will refund it with the next order.
