Product Application - Drag Chain Conveyor

         
 

4B has a wide range of sensors for monitoring the various parts of your drag chain conveyor. The most

 
 

common areas for monitoring include: bearing temperature, speed / motion, level / plug indication and

 
 

slack / broken chain detection.

 
     
 

All of 4B's sensors can be connected to our hazard monitoring systems.

 
     
 

4B also has has an entire line of material handling products, including - drop forged chain.

Bearing Temperature Sensor
 

(1) Bearing Temperature Sensor

The sensor screw directly into a bearing housing through the existing grease zerk thread. Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for
removal of the sensor.

Drop Forged Chain
 

Drop Forged Conveyor Chain

4B’s drop forged conveyor chain is made of special heat treated alloy steel case hardened to Rockwell C57 - C62 with a ductile core hardness of Rockwell C40. 4B’s superior heat treatment technique provides the optimum chain link with a more resilient ductile core for shock resistance, and an extremely hard exterior surface for superior wear resistance.
