Double plus chains are designed for accumulation conveyor systems and material transfer equipment. The chain structure shown in the technical drawing includes multiple rollers, chain plates, pins, and connecting components.
The product range in the supplied parameter table is divided into two types:
The available specifications cover chain pitch, roller dimensions, plate thickness, plate height, pin diameter, pin length, and weight per meter.
These specifications can be used by conveyor manufacturers, system integrators, equipment suppliers, distributors, and maintenance teams when selecting or replacing double plus chains.
The supplied technical drawing shows the main structure and installation dimensions of the double plus chain.
The drawing includes:
The actual chain configuration should be confirmed against the conveyor drawing, sprocket arrangement, guide rail structure, and operating conditions before production.
The Plastic Roller Type range includes the following models:
The plastic roller table includes two model groups: BS25 and BS30. The specifications vary according to pitch, roller dimensions, roller width, plate thickness, plate height, pin diameter, pin length, and weight per meter.

Download the Steel Roller Type Double Plus Chain Parameter Table
The supplied data distinguishes between Plastic Roller Type and Steel Roller Type chains. This allows customers to compare the available roller configuration according to the conveyor design.
The listed chain models cover pitch values from 19.05 mm to 50.80 mm. The correct pitch should match the sprocket, chain path, guide rail, and conveyor layout.
The tables provide model-specific values for:
The Plastic Roller Type is divided into BS25 and BS30 model groups. The Steel Roller Type is divided into standard VR and VR-B model groups.
The selected model should be confirmed according to the original chain number, equipment drawing, sprocket dimensions, and operating conditions.
Double plus chains can be evaluated for the following equipment and material-handling applications:
The correct roller type depends on the conveyor structure, product contact requirements, guide rail design, operating cycle, and equipment environment.
The project requires evaluation of the BS25 or BS30 series and the conveyor design is based on the plastic roller dimensions shown in the supplied table.
Please confirm:
The project requires evaluation of the 2030VR–2080VR or 2030VR-B–2080VR-B series and the conveyor design is based on the steel roller dimensions shown in the supplied table.
Please confirm:
The final roller type should be selected from the approved equipment drawing and the actual conveying requirements.
The chain number should match the original equipment specification, existing chain sample, or approved technical drawing.
The supplied tables list pitch options from 19.05 mm to 50.80 mm. Pitch must match the sprocket and chain track.
Confirm R, R1, W1, and W2 dimensions against the guide rail, product-support surface, and conveyor structure.
Plate thickness, plate height, pin diameter, and pin lengths affect installation compatibility. These dimensions should be checked before ordering replacement chains.
The listed weight per meter can be used for equipment design reference and chain-length estimation. Final conveyor calculations should use the approved chain specification and actual operating conditions.
Please provide sprocket details, guide rail drawings, conveyor photographs, chain samples, or equipment specifications for compatibility review.
