PU timing belt with guide profile

TIMING BELT WITH GUIDE PROFILE

We offer open timing belts with a guide profile that centers and corrects the belt's position during operation. Timing belts with guide profiles eliminate the need for flanges on the pulley, as the guide profile guides the belt longitudinally, ensuring stable and synchronous belt tension. Guide profiles are particularly suitable for timing belt drives where parts are fed from the side, as lateral influences can occur. Timing belts with guide profiles are primarily used for linear guides, as well as in vertical and rotary drives.
A guide profile is applied either by welding it into the tooth surface of an existing timing belt or by extruding it during the manufacturing process. The extrusion method increases durability and strength because the guide profile and timing belt are extruded as a single unit. We offer a wide range of guide profiles made of thermoplastic polyurethane in smooth and tinned finishes, available in white, transparent, green, and blue. All blue and white profiles are food-grade. Available versions include TK5-K6, ATK5-K6, TK10-K6, TK10-K13, ATK10-K6, ATK10-K13, HK-K13, and BATK10-K6.
 
An open guide profile timing belt can be assembled into an endless timing belt in your desired dimensions, either mechanically or by welding the belts together. The timing belt can be manufactured with welded fingers, or you can purchase your own welding equipment and weld the belt yourself. With a welded timing belt, you should expect approximately 50% less tensile strength than with a fully cast timing belt because the reinforcement in an open profile is overlapping. You can also obtain open guide profile timing belts that are mechanically assembled using pin mounting, which allows for easy and quick installation of the timing belt directly on the application. Open toothed belts with guide profiles can be advantageously provided with a nylon coating on the teeth or on the back of the toothed belt, which improves the running properties and reduces noise generation through a lower coefficient of friction.

An integrated wedge guide can be extruded during the manufacturing process to guide the timing belt. These timing belts can also be manufactured with a polyamide coating on the toothed or back side. The following timing belts are available with an extruded wedge guide.

Welded guide profiles

If special guides are required that are not available as extruded wedge guides, welded guides can be used as an alternative. These thermoplastic guides are welded into pre-machined grooves. This manufacturing process guarantees perfect and high quality.
