* Groove conveyor roller are commonly used in conveyor systems. These rollers provide better traction and prevent slippage, especially when handling heavy loads or moving materials on an incline.
 *The grooves increase the surface area in contact with the conveyed items, reducing the risk of slipping and ensuring efficient material transfer.         
 * Grooved rollers guide materials along a predetermined path. For instance, they help align paper or fabric in textile machinery, ensuring smooth movement during production.
   In woodworking equipment, grooved rollers assist in feeding wood through planers, jointers, and other machines.
