Quality starts with an agreed requirement
A conveyor component can only be assessed meaningfully against a defined specification. Before production, the customer and supplier need a shared understanding of the product, application, drawing revision and acceptance requirements. For a replacement part, fit is as important as the general product description. For a new installation, the component must also reflect the conveyor’s design basis and operating duty.
Our quality approach covers material selection, production and the finished product. It connects the information provided at enquiry with the checks relevant to the order. The exact inspection scope depends on the component being supplied: a roller, pulley, frame and belt do not have the same construction or acceptance criteria.
1. Confirm the technical basis
Provide a drawing or dimensioned specification and identify the document revision. Explain where the component is installed and the operating environment. If a standard is required, name the applicable document and edition along with any additional project requirement. General statements such as “heavy duty” or “international standard” should be supported by the dimensions, duty and acceptance criteria that matter to the actual order.
Important review points can include material or construction, interfaces, finish, identification, inspection and packaging. Where a change is agreed after the first enquiry, the updated information should be identifiable so that the production team and the customer are working from the same requirement.
2. Review materials and preparation
The material and component requirements follow the confirmed specification. For rollers and pulleys, this includes the shell or drum, shaft and associated assembly details. For belts, the carcass or reinforcement and cover requirements are part of the review. Any request for supporting material documentation should be raised with the enquiry, including the form of record and the item to which it must apply.
Preparation is an opportunity to identify obvious discrepancies before they pass into assembly. Dimensions and visible condition can be checked against the agreed requirements. The aim is to make the relevant control points clear rather than substitute a generic checklist for the actual product.
3. Check dimensions and interfaces
For replacement rollers, distinguish working length, overall length and the dimensions of each shaft end. For frames, mounting centres and the roller arrangement need to match the intended structure. For pulleys, face width, shaft details, bearing positions and the drive connection can all be critical. A component that looks similar may still be incompatible with the installation.
Where tolerances or fit requirements are important, show them on the drawing. The inspection discussion can then identify what will be measured and the acceptance limits that apply. If the customer needs dimensional records, the requested format and coverage should form part of the order review.
4. Consider assembly and functional checks
Depending on the product and agreed scope, checks may address the assembled condition, roller rotation, sealing arrangement, surface condition or runout. Belt inspection depends on the selected construction and order requirements. Any performance test, sampling plan or special test method needs to be agreed specifically; it should not be assumed from a general product family name.
Additional project requirements may include witness inspection or an independent inspection organisation. Raise these before production so that the timing, responsibility and documentation can be discussed. Agreeing the inspection point early is more useful than requesting an unavailable record after the product has been packed.
5. Confirm identification and protection
Item marking, drawing references and package identification help prevent confusion where similar components are shipped together. Tell us if your stock code, item number or project reference needs to accompany the goods. Discuss any special handling, separation or destination requirement as part of the packing agreement.
Certificates and project documents
Our company information refers to ISO 9001 and SGS-related quality documentation. If your purchasing process requires evidence, request the applicable documents for review and check their scope, issuing details and current status. Company management-system documentation is different from a product-specific test report or a project approval. The documents required for your order should be identified individually.
