Mesh belt dimensions should specify width, length or circumference, seam type, installation orientation and the measurement state. A width-by-length figure alone can omit information needed for correct installation. Measurements from a used belt should not automatically become the manufacturing dimensions for a replacement.

Use an approved drawing and technical agreement to define the dimensions, measurement method and allowable range. Then compare the new belt, the old belt and the equipment information on the same basis.

Define width, length and circumference clearly

For width, identify whether the measurement includes edge treatments or other special features. For length, identify the form and condition of the belt being measured.

An endless belt requires an agreed circumference measurement. Do not mix an open-belt dimension, a pre-joining length and a dimension measured after installation without explaining their relationship.

The seam may affect the dimensional definition and assembly arrangement, so confirm it with the dimensions rather than adding it later. Keep the dimensional drawing and seam instructions consistent.

When discussing a replacement with YIHENG, provide the equipment information and original drawing if available, then add the used belt's measured dimensions. This distinguishes the design requirement from the belt's condition after service.

Include these fields in a mesh belt inquiry

Tolerances must come from the applicable agreement and technical documents. Do not transfer them from an unrelated belt or machine.

Measure consistently before comparing results

Agree on the method first. Use suitable measuring equipment and support conditions, avoiding twists, folds or unexplained external forces that could affect the reading.

Record the measurement state. A relaxed measurement and a tensioned measurement should not be compared as though they were obtained under identical conditions.

Measure at the agreed locations and retain individual readings rather than relying on one point to describe the whole belt. If readings differ, record their positions and repeat measurements before deciding whether the cause is the measuring setup, the belt's condition or an actual dimensional discrepancy.

Do not stretch the belt merely to obtain a value closer to the order. The purpose is to produce a repeatable measurement, not to force the material to a target number.

Can the old belt be used as the replacement template?

A used belt is a useful reference, but its measurement needs an operating history. Tension, temperature, maintenance and structural condition may affect the measured result. The current dimension is not necessarily the original manufacturing requirement.

Supply the following where available:

• Original order, approved drawing or model reference.

• Used-belt readings, measuring method and measurement state.

• Machine tensioner position and relevant installation information.

• Records of mistracking, local distortion, seam damage or width changes.

• Confirmation of whether the replacement will serve the same product and conditions.

If the original records are missing, ask the belt supplier and machine provider what additional information is needed. Do not rely on a single used-belt length as the complete specification.

Why check the seam if the dimensions are correct?

Dimensions establish only part of the installation fit. The seam construction, connection condition and any orientation markings still need to match the belt and equipment instructions.

Not every seam has identical directional requirements. Check the actual design rather than applying a rule from another belt. If markings are missing or conflict with the drawing, resolve the discrepancy before installation.

If a delivered belt appears dimensionally incorrect, preserve the packaging and measurement records. Do not attempt to make it fit by forcing, cutting or carrying out an unapproved modification.

Frequently asked questions

Is width and length enough to confirm an order?

No. Confirm the dimensional definitions, measurement condition, seam and installation position as well.

Are endless circumference and open length interchangeable terms?

Not without qualification. Their relationship depends on the belt construction and agreed drawing. State the measurement method explicitly.

Does one acceptable width reading establish dimensional conformity?

Follow the agreed measurement locations and method. One reading does not replace the required checks.

Does a difference between old and new belt length prove a manufacturing error?

Not necessarily. First compare the model, original requirement and measurement conditions, then consider changes during use.

Can the tensioner accommodate a small dimensional difference?

Do not assume so. Confirm the machine's adjustment range and the belt's allowable conditions before installation.

Turn dimensions into an agreed specification

Clear dimensions combine numbers with definitions, measurement conditions and seam information. Recording these together reduces avoidable misunderstandings at ordering and installation.

To discuss a YIHENG replacement, submit the dimension drawing, seam photographs and machine details, including any used-belt measurements. Visit the nonwoven mesh belt product category for the relevant application range.
