CONSTRUCTION:
Optibelt VB classic V-belts are manufactured using the same production processes as those for optibelt SK high performance wedge belts. Consists of;

Top layer
Polyester tension cord
Core
Cover fabric

Cord: Rubber coated polyester tension cords to fuse with belts core.
Rubber: Engineered polychloroprene top and core layer for increased durability.
Wrap: Fabric wrapped for increased grip strength and greater wear resistance. This specialized wrap is rubber impregnated to fuse with the belt’s core.

The components used are perfectly suited to the power ratings PN. These values are far above those given by
DIN 2218. Thus the operational safety in existing drives is increased and overloading is avoided.
•  optibelt VB classic V-belts have a height-width ratio of 1:1.6.
•  The maximum belt speed vmax = 30 m/s should not be exceeded.
•  The allowed flexibility rate is far below that of wedge belts. It is fB max = 80 s-1.

APPLICATIONS
optibelt VB classic V-belts are mainly employed as replacement parts for industrial drives. For new drives, the use of high performance wedge belts is almost always recommended due to reasons of space and cost. However, special drives such as V-flat drives can often only be operated with classic V-belts. In special constructions, optibelt VB classic V-belts tackle difficult drives in the gardening sector and in agricultural machinery. For these applications special belt constructions and calculation methods are required which are not included in this manual. In these cases we ask you to give us the according drive data.
