Mining Conveyor Components
SINOCONVE mining conveyor rollers are designed to support belt conveyor operation in material handling, manufacturing, construction, energy and mining environments. The roller assembly can be matched to the conveyor frame, belt width, load conditions and selected roller position.
Product images are for reference. Confirm the final type, dimensions and bearing configuration before production.
A conveyor roller is not selected by diameter alone. The tube, shaft, bearing, seal, roller length and mounting ends must work with the conveyor frame and belt path. For a more accurate quotation, provide the existing roller drawing, a sample photo or the required installation dimensions.
Used for general belt support where a straight roller arrangement is required.
Selected for impact-support or return-side cleaning positions after application review.
The appropriate roller type depends on the belt position, conveyed material, belt speed, load and surrounding conditions. Confirm whether the project requires a flat, buffer or cleaning configuration before ordering.
| Specification | Reference information | Selection note |
|---|---|---|
| Application | Mining and material handling | Also applicable to manufacturing, construction and energy environments |
| Roller type | Flat / Buffer / Cleaning | Select according to the belt position |
| Diameter | 76–219 mm | Confirm belt width, spacing and load before final selection |
| Length | 190–3500 mm | Confirm face length, frame opening and shaft extension |
| Tube material | Carbon steel | Wall thickness and surface finish follow the approved drawing |
| Shaft material | Cold-drawn round steel | Shaft ends must match the mounting arrangement |
| Shaft diameter | 20 / 30 / 35 / 40 mm | OEM shaft dimensions can be reviewed |
| Bearing model references | 204 / 205 / 305 / 306 / 308 / 310 series | Final bearing selection depends on diameter and operating load |
| Pipe thickness | 3 / 3.5 / 4 mm and OEM | Confirm the actual wall thickness for the project |
| Color and packing | Red or black / OEM; carton | Color, logo and packaging requirements should be confirmed before production |
The following table is provided for preliminary conveyor roller matching. The listed combinations are reference values and should not be treated as confirmation that every option is available for every roller structure.
