Double-sided V-belt HBB 3730 Lw BB 144" optibelt DK

Product detailed description

The HBB 3730 Lw BB 144" double-sided V-belt from Optibelt, also known as a hexagonal belt, is specially designed for power transmission in drives with reverse operation or with external tensioning, where the belt contacts both sides. The HBB profile, sometimes also known as BB, determines a belt width of 17 mm and a height of 13 mm. The calculated (center) length of the belt is 3730 mm, with an inner length of 3705 mm and an outer length of 3755 mm. These dimensions are important for accurate sizing in applications where exact matching with the drive system is required.

The belt is made of a durable rubber compound and is equipped with a textile covering that provides protection against abrasion, dust, oils and temperature fluctuations. The symmetrical design with a central tension member ensures even force distribution and high strength at double-sided load. This design allows for quiet and smooth operation even under high loads and dynamic operating conditions.

The Optibelt DK belt is suitable for technically demanding applications such as conveyors, return rollers, agricultural and forestry machinery, or industrial drives with reverse operation. Thanks to its robustness, reliability and antistatic properties according to ISO 1813, it is also ideal for demanding operating environments with limited space and requirements for a long service life. The minimum pulley diameter for this belt is 125 mm, which is an important parameter when designing drive systems.
