OEM Conveyor Roller Manufacturing
Ningbo Sinoconve Belt Co., Ltd. supplies steel conveyor idler rollers for mining, energy and material handling systems. Buyers can discuss flat, buffer or cleaning designs together with the required diameter, length, bearing, shaft and pipe thickness.
Images are product and manufacturing references. Confirm the final configuration on the approved drawing before production.
Conveyor idler rollers must be matched to the complete belt conveyor rather than selected as an isolated part. Our OEM-oriented supply process supports technical discussions based on a drawing, sample, existing roller or project specification. The tube, shaft, bearing, seal and end configuration can then be reviewed together.
The final roller type depends on the belt path, conveyed material, loading conditions, belt speed and frame arrangement. Share the installation position when requesting a quotation.
