For tensioning on the outside of the belt (back of belt)
Ball bearing mounted, ready-to-install tensioning rollers with mounting screw
Mounted rigidly as idler or on tensioning element as elastic belt tensioner
Tensioning element has to be ordered separately (Cat. No. 700625 ff).
Roller: high-grade industrial plastic
Mounting screw: zinc-plated steel
Washer: zinc-plated steel
Nut: zinc-plated steel
Bearing: roller bearing steel, permanently lubricated and sealed
Temperature range: -20 to +80 °C
Use for power transmission, bridging of large centre distances and alteration of transmission ratios.
For various applications in machinery and plant engineering, in laboratory technology, in industrial and food processing plants, as well as in model making.
Quiet operation and synchronous transmission of power
Maintenance-free. Lubrication is not required.
High efficiency up to 98 %
Belt pre-tension is required
T timing belts made of polyurethane with pitch 2.5 or 5 mm. Light-coloured belts with little abrasion. For standard applications in machine building and food technology, to be used on T pulleys.
AT timing belts made of polyurethane with pitch 5 mm. Reinforced type for high loads with low space requirements. To be used on AT pulleys.
HTD timing belts made of neoprene with pitch 3, 5 or 8 mm. For high power transmission even at high speeds.
Black belts with dark abrasion (not for laboratory operations / food processing). To be used on HTD pulleys.
Notes on mounting and usage:
Pulleys must be aligned (precisely positioned)
The belt tension has to be adjusted (The overall sum of tensioning and peripheral force must not exceed the permitted tensile force of the belt.)
At least one pulley must be equipped with flanges.
And at least 6 teeth should be engaged at any time.
Timing belt drives run without lubrication.
