Should You Tighten the Conveyor Belt? Understanding Belt Tension
Begin to add product and tension the belt as needed until the conveyor will move the heaviest load without the belt slipping. When the belt is no longer slipping, stop the conveyor and place a full product load on it. Restart the conveyor and check for belt slippage. If slippage occurs, repeat as necessary. Other Belt Care.
The Essential Guide to Conveyor Roller End Bearings
For conveyor belt rollers, the selection of bearings is crucial for ensuring smooth operation, durability, and efficiency of the conveyor system. The ideal type of bearing depends on several factors including the conveyor's operational speed, load capacity, environmental conditions, and maintenance requirements.
