What the supplier catalogue establishes
Jiangsu Wanda lists MGxxA1-x as a straight cylindrical mast-roller family using a single row of balls. The parameter table contains numerous complete references, including MG20A1-1. The letters and placeholders in the family code are not a complete order number: the specific catalogue reference and any suffix must remain attached to an enquiry.
Read the published size in context
The supplier’s MG20A1-1 row gives a dimensional string of 20 × 65 × 20/15 mm under its d × D × C/B heading. That row is a useful identification example, not a dimensional specification for the whole family. Request the current drawing and confirm the meaning and orientation of each dimension. A similar outside diameter does not establish the same bore, shoulder, width, contact profile or installed clearance.
Keep the supply package explicit
Ask whether the proposal covers the complete mast roller or only a bearing element. Keep the installed mast identity, the roller reference and any shaft or mounting hardware as distinct records. A quotation should identify the supplied assembly and any excluded items. The catalogue’s other reference numbers are discovery aids; this page does not approve an interchangeable replacement or transfer a load rating to a truck application.
Questions for the proposed component
Can the family code be used as the order number?
Not by itself. Ask for the complete variant, suffix and drawing revision, and keep them on the quotation and delivery identification.
What should be photographed?
Provide the existing roller marking, its full outer profile, visible mounting arrangement and the machine or mast identification. Do not rely on a cropped bearing number alone.
Does the dimensional example confirm a replacement?
No. The current drawing, installed assembly information and supplier’s matching explanation still need to agree.
From product research to a comparable request
Prepare an identification pack with the truck model and serial information, mast or attachment identity, complete installed component reference and clear photographs. Include available drawings and preserve their revision identifiers. Ask shortlisted suppliers to state the exact proposed item, supplied assembly scope, condition, origin statement, matching basis and unresolved differences. Keep quantity, destination, packing, delivery and warranty questions separate from the technical identity. A catalogue picture or similar dimension does not by itself establish a suitable replacement.
Sources and evidence boundary
The company-controlled product page establishes the named family and the selected published parameter example. It does not establish stock, authorization, a confirmed interchange, certification, an allowable wear limit or suitability for a particular mast. Published load-rating, service-life, market-position and performance claims are not independently verified or used as purchase assurances here. Obtain the current component drawing and a documented matching explanation for the actual assembly. This page gives no adjustment, repair, dismantling or return-to-service instruction.
