Belt Description

BB3981 Le BB154 DOUBLE V-BELT SWR is a double-sided or double V-belt for conversions with change of direction of rotation. It is made according to ISO 5289 (DIN 7722).

The belt's dual-wedge section makes it especially suitable for drives with reverse flexing where both sides of the belt are to be used to transmit power. The symmetrical design of the belt allows the power transmission to be divided on both sides, each side transmits about 50% of power as the classic V-belt of the same profile.
