We have a complete range of polyurethane round belts for conveying and power transmission applications. PU round belts, extruded in open lengths, are homogeneous round profiles that can be welded for use as high-quality power transmission and conveying elements. Our stock mainly comprises solid profiles with a smooth or slightly roughened surface and hollow profiles for nipple connections. Several types have FDA/USDA approval and comply with EU Directive 2007/19/EC. Although we generally produce in open lengths, we can also produce all belts according to your specifications. Our round belts convey a wide range of products such as foodstuffs, glass, roof tiles, PC boards and many more. The standard range of round belts is rounded off with aramid, polyester or glass-fiber reinforcements. If an appropriate quantity is purchased, we also produce special types with PES or aramid reinforcements.

Our endless turned round belts are wound either out of one homogeneous strand or one cord and spliced endlessly without thickening. For special applications, it is possible to vulcanize the inner splice or to make a special splice based on our in-house engineering methods. This increases the tensile strength by up to 60%. In elastic types, the core is welded. In view of their special structure, twisted round belts exhibit very quiet running properties, are extremely flexible and, thus, make possible very small minimum pulley diameters of 3x belt diameter. For several types, speed up to 70,000 rpm is possible; however, the speed of 60m/s should not be exceeded. Elastic types: PU, Vulkollan Semi-elastic types: PA.6, Set-Polyester, Nylon, HE Types with limited extensibility: Polyester, Nomex, Nomex-PTFE, Polyester-PTFE, Kevlar/Twaron, PA.6 anti-static, PBO

Endless extruded round belts Our endless extruded round belts are ideal for low power requirements. They are elastic power transmission elements that do not need cost-intensive tensioning devices. In view of the special production process, they do not have any welding seams or terminal connections and run very smoothly. Moreover, they allow a minimum pulley diameter starting from 5.5 x belt diameter. Our types E80, V75, C70 and P82 are made of specially selected and dynamically tough materials. In addition, type E80 also is antistatic to a limited extent and has a resistance value of about 106 Ohm; thus, it is excellent for use in electronic devices and chip production. Available diameters: 1.8mm - 7mm Available lengths: 40mm – 1,610mm Temperature resistance: -20°C - +160°C Coefficient of friction: 0.35µ - 0.9µ* Maximum tension: >100N
