Product detailed description

The HBB 5639 Lw BB 221" double-sided V-belt from the manufacturer Optibelt, also known as a hexagonal belt, is specially designed for applications with reverse operation or external tensioning, where the belt contacts both sides. The HBB profile, also known as BB, indicates a belt width of 17 mm and a height of 13 mm. The calculated length Lw is 5639 mm, while the inner length Li is 5614 mm and the outer length La reaches 5664 mm. The minimum diameter of the pulley for which the belt is suitable is 125 mm.

The belt is equipped with a central tension member, which ensures even force distribution and high strength under double-sided loading. It is made of a durable rubber compound and has a fabric covering that provides protection against abrasion, dust, oil and temperature fluctuations. This design allows the belt to provide quiet and smooth operation even under high loads and dynamic operating conditions.

Optibelt DK is suitable for technically demanding applications such as conveyors, return rollers, agricultural and forestry machinery or industrial reversing drives. 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.
