What the official reference establishes
The official JQR053 detail identifies a rigid, fixed-direction polyurethane caster, distinct from a swivel assembly. Its specification table lists JQR05300-80*40ALCPU010102, JQR05300-100*40ALCPU010102 and JQR05300-125*40ALCPU010102. Wheel diameters are 80, 100 and 125mm, with a 40mm width and published load entries of 250, 300 and 350kg respectively. These remain individual catalogue rows, not a universal load rating for the whole family.
Define the work before choosing a configuration
Keep diameter, mounting height, top plate, hole spacing, axle and wheel material together in the request. The table gives a 105 × 85mm plate, 86 × 60mm hole spacing and an 8.5mm hole entry for the listed rows. Confirm the current drawing and fit rather than treating a similar bracket as interchangeable. The clean gallery artwork also mentions a broader 250–500kg range and larger sizes; that graphic is not used to extend the three-row detail table to an undocumented configuration.
Keep the supply package explicit
The source-based illustration follows a single black wheel in a fixed steel bracket. The supplier lists JPZK03 polyurethane, a nominal Shore 93A±3 tread and an aluminium double-bearing core, but those material descriptions are not independently tested here. Ask for the exact offered compound, bearings, corrosion finish, wheel/bracket assembly and drawing revision. Printed ESD, RoHS or other marks on source graphics are not adopted as verified certifications or electrical properties.
Questions for the proposed product
Which full code and assembly are being offered?
State the exact diameter, width, mounting, material, bearings, mechanism and included components. Preserve every suffix and obtain the current assembly drawing.
What establishes the actual duty and fit?
Provide the equipment identity, load distribution, route, floor, interfaces and envelope. Ask the supplier to explain dynamic-load and environmental assumptions. Multiplying catalogue caster ratings does not establish equipment payload.
What is included in the quotation and support route?
Identify the legal supplier, quantity, condition, drawing revision, documents, samples where agreed, delivery and warranty terms. Stock, certification, fitment and application performance are not established by this reference.
From product research to a comparable request
Prepare one written component requirement around equipment identity, full caster code, load conditions, mounting dimensions, floor and travel route. Compare tread, bearings, swivel or fixed layout, springs, brake or leveling interfaces, drawing revision and support responsibilities. Keep unresolved differences visible. Existing supplier and procurement tools remain available below; browsing or following links does not itself send an enquiry.
Sources and evidence boundary
The official About page identifies Jujiang Intelligent Technology (Huzhou) Co., Ltd. as the operator of JP CASTER and publishes the southwest gate of No.2688 Nianfeng West Road, Nanxun District, Huzhou, Zhejiang, matching the existing supplier profile. The selected product bodies, parameter tables and labelled images were read directly. This is supplier-published information, not an independent factory audit, load test, material analysis or certification. Undated pages and upload-folder dates do not establish a product launch date. No stock, authorization, verified compliance, service life, fitment or application safety is claimed. Ask for the current exact-code drawing and written supply package. No installation, adjustment, electrical, brake-service or operating procedures are provided.
