Castor & Wheel Selection Guides

Use guides as decision tools

These guides are organized around questions that appear before quotation: what load each wheel may see, which dimensions control fit, which mounting style the equipment uses, how the floor affects wheel choice and how trailer support assemblies should be measured.

A consistent measurement language

Procurement teams often encounter castor wheel selection guides as a catalogue term, but the purchasing decision becomes clearer when the term is converted into measurable operating requirements.

In industrial procurement, the selection should therefore start with load, dimensions and operating environment. That keeps a dimensional or material choice connected to the job it must perform rather than to a generic product description.

The common failure is to treat one attractive parameter as the whole specification. Different teams may use the same product word for different assemblies. A better purchasing note captures one drawing or photo set, named dimensions and model-specific quantities, so suppliers can compare like with like and flag missing dimensions instead of guessing.

Use the guides with the catalogue

Once the application is defined, compare product families. If the issue is replacement, use the 測定ガイド. For trailers, combine the application guide with the jockey-wheel checklist.

Start with measurements, then use the guide that answers the next decision

A selection guide is most useful when it reduces one uncertainty at a time. If the existing part must be replaced, begin with measurement. If the equipment is new, start with load and supporting points. Once the physical envelope is known, material, wheel diameter, mounting type and control functions can be compared without mixing unrelated decisions.

Keep the measurement sheet next to the guide notes. This prevents a general recommendation from being mistaken for a dimension or rating of a specific product.

Separate guidance from product-specific ratings

The guides explain how to ask the right questions; they do not turn a generic wheel family into a rated assembly. Load capacity, material grade, mounting dimensions and compatibility should be confirmed for the actual configuration being quoted. This distinction lets the engineering pages remain useful without forcing unlisted values into product pages.

When a required value is not shown on a product page, include it in the RFQ rather than guessing. That keeps the technical discussion tied to the real equipment.

Build a reusable selection record

For fleets or repeat purchasing, keep the accepted wheel or assembly together with its application notes: equipment family, load assumption, floor or ground, mounting interface, dimensional drawing, material, finish and any brake or folding requirement. This small record often saves more time than starting from a product photograph for every reorder.

Recheck the record when the payload, route, floor, equipment frame or cleaning environment changes. A repeat part number should be a controlled baseline, not a substitute for reviewing a changed application.
