Keiper PU Flex timing belts are extruded of abrasion-resistant polyurethane and high-strength steel cords, aramid cords or high flexible steel cords and VA steel with endless winded cords. In these belts the cords are helically spooled. These timing belts can be used for all kinds of power transmission applications because of their high power transfer, and their high flexibility make them suitable for synchronous transport and positioning applications. By using standard polyurethane and such other belt materials as polyurethane that is cold resistant, heat resistant or suitable for contact with foodstuffs a wide spectrum of applications is possible.

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

Keiper self-guiding PU track timing belts are made of abrasion-resistant polyurethane and high-strength steel cords or aramid cords and produced in open lengths. The V-guide is either integrated in the timing belt during production or welded into the belt later. These timing belts exhibit the same properties as standard timing belts. In addition, axial movements are prevented. Keiper self-guiding PU track timing belts are available as endlessly welded belts and cut goods, in almost any length and width. Properties and special features: Prevent axial movements V-profile guides can be combined with any tooth profile in all sizes Flanges are no longer required, the notched design of the V-profile guide gives rise to high flexibility Applications: Conveying and positioning applications with large center distances Applications, in which axial movement is a problem and flanges cannot be used.

Keiper open-ended PU timing belts are made of abrasion-resistant polyurethane and high-strength steel cords or aramid cords and are available in open lengths. These timing belts are very suitable for synchronous conveying and positioning applications because they have very high flexibility and can be made with many different tooth shapes and materials; when combined with different tension cords, innumerable applications are possible. Keiper open-ended PU timing belts can be produced endless welded and by the meter in almost all lengths and widths. Based on this combination of high-quality materials and production methods, these belts exhibit outstanding mechanical, chemical and physical properties. Endless welded timing belts are available in any length. Welded PU timing belts primarily are used in conveying technology.

The range of application for the high-precision resistance decades models 1406 and 1407 stretches from reference standard for precision measurements up to simulation ot a host of measuring transducers. They can be used for control in complicated equipments and systems, such as equivalent circuit in resistor networks. Another application is the use in switching circuits, as reproducible variable in laboratory and test assemblies. The decade resistors meet all the requirements of these differing functions as well as the resulting demands. The high-precision resistance decades models 1406 and 1407 are designed to meet the highest demands with regard to precision, temperature and long-term consistency. Many years at experience, tried-and-tested technology and the use of fieldproven materials guarantee the high level of precision. The decade resistors consist of low-capacity and low inductance wire windings of MANGANIN®.
