The optibelt HTD- timing belts have curvilinear, particularly shear-resistant teeth. 

The tooth geometry in conjunction with the belt construction produces uniform oad distribution and optimal meshing of the belt teeth in the timing belt pulleys. 

HTD® timing belts are also available in a double section version.

The merits of the optibelt HTD- and HTD double timing belts make them suitable for heavy duty drive systems, in particular low speed systems with high starting torque.
