Steel belt conveyor carry roller for heavy duty coal mining
Product Description
The roller pipe is made of ERW steel tube, and the shaft is made of cold-drawn steel bar. Both materials are specially designed for conveyor rollers. Shaft tolerance is controlled within -0.01mm to +0.01mm to ensure proper bearing installation.
Automatic cutting equipment ensures consistent length for both pipe and shaft. The inner wall of the pipe is painted to prevent rust and extend roller life. After cutting, both ends of the shaft are milled using specialized equipment.
Double-end boring equipment processes the pipe ends to ensure bearing housing concentricity. A four-cutter milling machine works simultaneously to maintain consistent flat distance on the shaft. Both-end welding keeps the bearing housing aligned and concentric.
A CNC lathe machines the seal grooves with high precision and smooth finish. Bearings and seals are then assembled into the roller. After assembly, each roller goes through inspection and final painting.
