JUKI 40107797, 40046935, 40046936, 40046937, and 40075460 SMT conveyor belts are designed for PCB transfer sections in compatible surface-mount placement equipment. These belts support stable board loading, internal transport, positioning, and unloading during continuous SMT production.
The product group includes different belt positions and configurations rather than one universal belt. Verified references include 40046935 Conveyor Belt S, 40046936 Conveyor Belt J, 40046937 In/Out Conveyor Belt, and 40075460 Conveyor Belt S(E). The first three references are commonly associated with FX-3 and FX-3RA conveyor assemblies, while 40075460 is commonly listed as an S(E)250 or S(E)350 conveyor belt for selected JX and related machine configurations. Compatibility must always be confirmed using the machine model, rail specification, original belt label, belt dimensions, and installation position.
These replacement belts are suitable for preventive maintenance, emergency repairs, production-line rebuilding, and spare-parts inventory. Send us your machine model, original part number, belt photo, and dimensions for faster identification and quotation.

Public spare-parts lists identify 40046935 as Conveyor Belt S, 40046936 as Conveyor Belt J, and 40046937 as the In/Out Conveyor Belt for FX-3 or FX-3RA equipment. Public catalogs also identify 40075460 as Conveyor Belt S(E)250 or S(E)350.
SMT conveyor belts operate continuously under repeated loading, tension, friction, and temperature changes. Although the belt may appear simple, its condition directly affects PCB transfer stability and machine availability.
The belt surface gradually becomes smooth, polished, cracked, or locally damaged. Reduced friction can cause the PCB to slip during loading or unloading.
Long operating hours may cause the belt to stretch. An elongated belt can lose correct tension and may move unevenly around the drive and guide pulleys.
Incorrect tracking, damaged pulleys, excessive tension, or misaligned rails can wear the belt edges. Frayed material may create particles or interfere with nearby mechanisms.
Dust, lubricant, adhesive residue, and production contamination can reduce belt grip. Contamination may also increase uneven wear between the left and right conveyor rails.
A belt that is too loose may slip or jump. A belt that is too tight can overload bearings, pulleys, shafts, or conveyor motors.
Installing a new belt without checking the pulley path may cause premature belt failure. Misalignment can force the belt toward one side and damage the belt edge.
Belts with similar color and appearance may have different length, width, thickness, surface texture, joint structure, or application position. Selecting only by appearance can result in installation failure.
| Production Symptom | Possible Belt-Related Cause | Recommended Check |
|---|---|---|
| PCB stops during transfer | Belt slipping or insufficient tension | Inspect tension and surface grip |
| Board moves unevenly | Left and right belts running differently | Compare belt condition and pulley alignment |
| PCB enters at an angle | Unequal tension or contaminated belt | Clean and synchronize both sides |
| Conveyor alarm occurs repeatedly | Belt resistance or incorrect routing | Inspect routing, pulleys, and sensors |
| Belt moves sideways | Pulley or rail misalignment | Correct tracking before operation |
| Belt edge becomes damaged | Excessive tension or contact with rail | Check clearance and installation position |
| Motor becomes unusually hot | Belt tension may be excessive | Reduce tension and inspect bearings |
| Unstable PCB positioning | Worn or stretched conveyor belt | Compare dimensions with a new belt |
| Increased particles inside machine | Belt edge fraying or surface deterioration | Replace belt and clean conveyor section |
| New belt cannot be installed | Incorrect part number or size | Reconfirm model, position, and dimensions |
The correct replacement solution begins with accurate identification. Each belt should match the original part number, machine configuration, conveyor position, and physical dimensions.
Our supply process can support the following identification methods:
| Identification Method | Information Required | Recommended Accuracy |
|---|---|---|
| Original part number | Clear label or parts-list reference | High |
| Machine model | Complete machine name and configuration | Medium to high |
| Installation position | Input, output, main, S, J, or S(E) section | High |
| Belt dimensions | Circumference, width, and thickness | High |
| Original sample photo | Front, rear, edge, and joint photographs | High |
| Machine serial number | Serial plate or production configuration | Useful for special versions |
| Old and new comparison | Side-by-side dimensional comparison | Very high |
For 40046935, 40046936, and 40046937, the standard part descriptions and FX-3/FX-3RA association are documented in public spare-parts catalogs. For 40075460, listings may describe the belt as S(E)250 or S(E)350, so the conveyor width and machine configuration should be stated in the inquiry.
For 40107797, please send a photograph of the original label. Public listings more commonly identify the JX conveyor belt group as 40107791, 40107792, and 40107793 for JX-200 and JX-300 machines.

The conveyor motor transfers rotational force to the drive pulley. The pulley moves the belt along the conveyor rail, and the friction surface of the belt carries the PCB by its edges.
The complete operating sequence generally includes the following stages:
| Working Stage | Belt Operation |
|---|---|
| Board arrival | The belt receives the PCB from upstream equipment |
| Sensor detection | A conveyor sensor confirms board presence |
| Controlled movement | The belt transports the PCB into the machine |
| Positioning | The belt slows or stops at the programmed position |
| Clamping or support | The machine secures the PCB for component placement |
| Processing | The conveyor remains stationary during placement |
| Release | The clamp or support mechanism releases the PCB |
| Board exit | The belt sends the PCB to the downstream machine |
| Cycle restart | The conveyor prepares to receive the next PCB |
Stable operation depends on more than the belt alone. The following components should be checked during replacement:
A high-quality replacement belt may still wear quickly when a pulley is damaged or the rail is misaligned. Inspecting the complete conveyor path helps extend service life.
Use the number printed on the belt packaging, machine parts list, maintenance record, or original label.
Do not rely only on the machine name. One machine may use several conveyor belts in different positions.
Confirm whether the belt is installed in the:
For example, 40046935, 40046936, and 40046937 are publicly associated with FX-3 and FX-3RA conveyor assemblies. The 40075460 reference is commonly described as an S(E)250 or S(E)350 conveyor belt, with application varying by machine configuration.
