JBL Mesh Belt / Small Radius Series
JBL Mesh Belt reviews turning geometry, belt width, link arrangement, drive interfaces and replacement evidence for compact spiral conveying paths. Final construction follows confirmed equipment data and an approved project drawing.
For new equipment, existing-belt replacement and repeat-supply projects. Start with a drawing, photographs or the measurements you can confirm.
Project route
The first review route depends on whether the belt is for a new machine, an existing-line replacement or repeat supply from an approved record.
New equipment
Review drum or cage geometry, belt path, turn direction, usable width, drive interfaces, product load, temperature and cleaning conditions before the belt construction is fixed.
Send first: Equipment layout, drum or cage dimensions, belt path and operating conditions.
Start this reviewExisting-belt replacement
A product name or nominal width is not enough. JBL Mesh Belt compares link layout, pitch pairs, rod and wire dimensions, edges, center links and drive details with the installed system.
Send first: Full-belt, edge and sprocket photos; caliper readings; drawing or sample if available.
Start this reviewRepeat supply
Use the previous approved drawing, reference dimensions and agreed inspection points as the starting record, then confirm any equipment or operating changes before release.
Send first: Previous drawing or order reference, quantity, required date and any changed conditions.
Start this reviewProduct family decision
These families can serve spiral or turning applications, but their drive and support logic differ. They are not interchangeable from the product name alone.
Compact spiral paths where pitch pairs, inner / center / outer link geometry and the project radius definition control the selection.
Confirm first: Turning geometry, link layout, belt width and drive interfaces.
Broader spiral freezing and continuous cooling projects using a reviewed spiral-belt structure and project-specific edges or accessories.
Confirm first: Drum geometry, turn ratio, edge route and support requirements.
Systems in which the side plates form and support stacked conveying tiers as part of the belt path.
Confirm first: Stacking height, side-plate geometry, tier clearance and drive route.
Systems where side or edge engagement is the primary drive interface.
Confirm first: Drive pitch, engagement geometry, sprocket or rail interface and edge clearance.

Drawing + mm / in table
Reference values below come from the current Small Radius technical specification. Listed options do not mean every combination is valid. Final dimensions, tolerances and combinations follow the approved project drawing.
Provide your equipment or belt drawing to confirm the named dimensions. O/A width means overall width.
Pitch pairs are inner / middle × outer. The 1.1 turn-ratio value is a reference under review; the formula, radius basis, belt-width definition and applicable structure must be confirmed for the project.
Send your drawing or old-belt measurements. JBL Mesh Belt will map the missing dimensions and interface data before quotation.
Start Technical ReviewDrive + replacement control
A compact turning path still depends on the complete system. Record these inputs before the replacement or OEM specification is approved.
Confirm the radius reference, drum or cage diameter, belt width, direction, inner / center / outer pitch relationship and available clearance.
Record the drive position, engagement surface, sprocket material, tooth count, bore and keyway. Existing sprockets must be reviewed with the belt rather than assumed compatible.
Use an old-belt drawing, labeled measurements, full and close-up photographs, sprocket details and a sample section when available.
Define the dimensions, edge details, finish, packing and any turning-trial requirement on the project record. Product photographs alone are not running-test evidence.
If a turning trial is required: agree the trial drum or radius basis, belt direction, load, speed, duration and acceptance points in writing. These project photographs do not document a powered running test.
Verified shipment evidence
The records below belong to one completed Small Radius project and are published in anonymized form. They confirm the photographed structure, measurements, finish and packing for that project only; they are not universal series specifications or operating-performance evidence.
19.05 mm pitch inspection
A caliper photograph from this completed project records the specified pitch point.
5.02 mm rod reading
The project record shows the actual caliper reading beside the nominal 5.0 mm rod specification.
Center-link structure
Close-up evidence of the project-specific center link, cross rods and spiral connection.
Protected belt sections in the case
An anonymized crop shows rolled sections, protective film and ties before the case was closed.
Wooden case with steel banding
An anonymized crop from the packing record. Customer, order, destination and shipment values are excluded.
Structure references
These white-background photographs show a three-link-row sample and its articulation. They are product-structure references, separate from the completed shipment evidence above, and do not establish an operating radius or compatibility result.
Customization
JBL Mesh Belt can review project-specific dimensions and structures. Customization remains conditional on the complete belt geometry, drive interfaces, operating conditions and approved drawing.
Reference ranges guide the discussion. Final values and valid combinations are released only after engineering review and drawing confirmation.
Buyer questions
Use these answers to prepare selection, specification, drive, replacement, installation and quotation data.
Engineering-controlled inquiry
Attach the equipment or belt drawing, old-belt dimensions, drive and sprocket details, operating conditions and available photos. JBL Mesh Belt will identify the next confirmation points for the project.
