Production process
The production reference covers steel pipe cutting, rust cleaning, tube-end processing, bearing-seat welding, assembly, shaft processing and surface painting. The final process and inspection requirements should follow the approved roller drawing and order specification.
Production capacity and factory references
Production capacity, inspection, packaging and delivery can be arranged according to the selected roller configuration, order quantity and destination. Logo printing, sample checking and project-specific dimensions should be confirmed before production.
Roller structure and technical drawing
The drawing reference identifies the shaft, seal, support, bearing and roller shell. For the steel ordinary roller, confirm the actual diameter, face length, shaft dimensions, single sealed bearing model, seal arrangement and mounting method from the final drawing.
The buffer-roller drawing is a related construction reference. Confirm the required roller type, impact position and conveyor application before quotation.
Reference steel conveyor roller specifications
The following reference combinations cover common roller diameters, face lengths and bearing models. They are reference options only; final availability depends on the selected conveyor structure, load conditions and approved drawing.
| Roller diameter D | Reference face lengths L | Bearing model references |
|---|---|---|
| 89 mm | 180–1150 mm | 204 |
| 108 mm | 190–1600 mm | 204, 205, 305, 306 |
| 133 mm | 305–2200 mm | 205, 305, 306 |
