Double-sided V-belt HBB 3150 Lw BB 121" optibelt DK

Product detailed description

Optibelt DK is a special double-sided V-belt designed for power transmission in drives 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 (central) length of the belt is 3150 mm, with an inner length of 3125 mm and an outer length of 3175 mm. This belt is equipped with a central tension member, which ensures uniform force distribution and high strength under bidirectional loads.

The belt is made of a durable rubber compound and is provided with a fabric covering that provides protection against abrasion, dust, oils and temperature fluctuations. This design allows the belt to ensure 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 drives with reverse operation.

Thanks to its robustness, reliability and antistatic properties according to ISO 1813, this belt is ideal for demanding operating environments with limited space and requirements for a long service life. The minimum pulley diameter on which the belt can be mounted is 125 mm. Optibelt DK is therefore the optimal choice for applications requiring high durability and reliable performance under difficult conditions.
