Fabric<br />
Top surface<br />
The belt top surface consists of a flexible polychloroprene compound<br />
which protects the tension cord from external influences. In<br />
addition, it is moderately resistant to mineral oils, humidity and<br />
protects from frictional wear.<br />
Tension cord<br />
The tension member is composed of glass fibre tension cords<br />
counter twisted and laid in pairs. These tension cords have high<br />
tensile strength, very high flexibility and very low stretch.<br />
Teeth<br />
Just like the belt top surface, the teeth consist of a polychloroprene<br />
compound guaranteeing high shear strength. The indent in the<br />
tooth tip promotes quiet running.<br />
Fabric<br />
The polyamide fabric protects the tooth from premature wear and<br />
prevents cracking. At the same time, the low coefficient of friction<br />
lowers operating temperature and helps to reduce running noise<br />
levels.<br />
Overview of the advantages and characteristics<br />
• synchronous speed<br />
• highest precision<br />
• perceptibly low noise level due to the OMEGA tooth profile<br />
• may be used in standard HTD ® and RPP ® timing pulleys<br />
• maintenance free<br />
• temperature resistant from –30 °C to +100 °C<br />
• efficiency of up to 98%<br />
• electrical conductivity can be checked to ISO 9563 on request<br />
High performance Optibelt OMEGA timing belts are the result of<br />
a continuing development process. Operational experience with<br />
Optibelt ZR and Optibelt HTD ® has been applied to this belt<br />
generation. Optibelt OMEGA timing belts set the standard for<br />
synchronous performance and for positioning drives.<br />
The geometry of the Optibelt OMEGA tooth profile has been<br />
adjusted to the established, curvilinear timing pulleys. You can use,<br />
for example, Optibelt OMEGA timing belts in HTD ® timing pulleys<br />
in the pulley sections 3M, 5M, 8M and 14M. Optibelt ZRS HTD ®<br />
timing pulleys are standard items in our <strong>range</strong> with pilot bores or<br />
bored for Optibelt TB taper bushes. In addition, all OMEGA timing<br />
belts can also be used in RPP ® timing pulleys. Special timing pulleys<br />
for Optibelt OMEGA timing belts are not required.<br />
