KEIPER round belt catalog

Keiper haul-off timing belts are made with polyurethane or neoprene timing belts that are finished with many different kinds of coatings. They are used for conveying foils in bag forming, filling and sealing machines as well as numerous other conveying tasks. The extensive range of designs offers the optimal solution for any transport task and application, e.g. with smooth or vacuum-processed surface, finished according to individual specifications, and with many different coatings. Timing belts - Polyurethane molded timing belts - or neoprene molded timing belts Tension cords - Steel - Aramid - Polyester Coatings - PU yellow - Linatex - Various elastomers - Silicone

Keiper PU molded timing belts (form belts), which are cast in special molds, are made of abrasion-resistant polyurethane and high-strength steel cords (or aramid cords). The cast PU timing belt is an exact replica of its mold. Consequently, high pitch accuracy along the entire length of the belt is realized. They are particularly well suited for smooth running and high speeds. By combining high-quality materials and this modern production method, the resulting timing belts exhibit supreme mechanical, chemical and physical properties. Mechanical properties: Low longitudinal tolerance Longitudinal stability, negligible elongation Form-fit, synchronous running Low noise High abrasion resistance Favorable performance-weight ratio Chemical properties: Good ageing resistance Operating temperature range from -30°C to +80°C Resistant to simple oils, greases and gasoline Applications All types of drives Office machines Textile machines Wood-processing machines

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
