Automatic belt tensioners
Round belts, V-belts as per DIN 2215, or flat belts - they all require different pre-tensioning. The following Spann-Box®/Spann-Boy® types are available as belt tensioners:
Material:
We use our tried-and-tested Original Material "S"® Black Antistatic for the ball-bearing supported tensioning roller that is attached to the housing. It is characterized by its excellent wear resistance, ideal slide properties, and very good resistance to chemicals.
Design:
Our standard tensioning rollers are supplied with a cylindrical surface or a profile of your choice. Use the profile shape table to specify the required profile along with the belt type used when you make your order.
