2 We supply you with the ideal solution by using the most up-to-date programs, for example the optibelt CAP Drive Calculation Program. optibelt ZR timing Belts optibelt ZR D Double Section timing Belts optibelt ZRS Standard timing Pulleys optibelt TB Taper BushesOptibelt ZR timing Belts have been developed for usage in Power drives. The drive speed is transferred in a synchronous manner. This means without loss of speed and in a manner with a constant transmission recommend the usage of the optibelt OMEGA timing Belts when using synchronous high Power would like to point out the advantages obtained by using 1 RVKDGNV #.

Both come in six standard sections. Due to the American origin of the timing belt section, the unit of length is the inch. The width/length codes have been derived from the appropriate imperial (inch) details with regards to the widths and 1: belt sections and tooth pitchTooth pitch is the distance from the centre of one tooth to the centre of the next measured at the pitch line, which corresponds to the level of the tension cord.

9 The top surface consists of a resistant, extremely thinly developed, high-quality chloroprene compound. This protects the tension cord from oil, damp and friction and wear and top surface is limited amount resistant to mineral oils, but not to vegetable and water soluble cooling and cutting teeth are made of a shear- and wear-resistant rubber compound bonded to the top surface to form a single mass. The shape and arrangement of the teeth are such that the pulley engages the belt teeth precisely and with minimum long as six teeth or more are in mesh on the small pulley, the complete capacity of the timing belt can be used without any CoverTo reduce wear and tear, the tooth faces are covered in a tough, friction-resistant fabric.
