Timing belts by the meter
Alphabelt PU timing belts are available either as open-length belting or as endless belts joined by welding. Both versions can be ordered in almost any length and in different widths. In welded timing belts, the tension members are interrupted at the joint. As a result, their tensile load capacity is lower than that of molded endless timing belts or Flex timing belts with continuous tension members.
Open-length timing belts with steel or Kevlar tension members are used as base belts for customised solutions and further finishing processes. By combining different polyurethane compounds, tension member materials and finishing options, the properties of the timing belts can be specifically adapted to various technical requirements.
Belt structure
- Belt body made of high-quality extruded thermoplastic polyurethane with high abrasion resistance. Special PU for particular applications available on request.
- Standard tension cords made of steel, optionally also stainless steel or aramid fibers with bifilar and spiral arrangement.
- Optional coating on the tooth side (PAZ), on the back of the belt (PAR) or on tooth and back side to reduce friction and running noise.
Special tension cords
Stainless steel
PU timing belts with tension cords made of stainless steel are particularly suitable for operation in damp and corrosive environments or under water due to their non-rusting properties.Aramid
Aramid fibers are very flexible, therefore contributing to the very good pliability of the belt and cushioning shocks. The belts weigh less than those with steel cords. However, they are more susceptible to stretching under load.Special materials
For an extension of the temperature range, timing belts made of special PUR are available which are suitable for operation from - 30 °C to + 110 °C. PU materials with documented FDA and EU compliance for food contact are also available.Product features
