keyless timing pulley

Barbieri® Tension sleeve keyless timing belt pulley has become a key component in modern mechanical engineering due to its unique expansion sleeve connection principle, the fact that no keyway machining is required, its high centering accuracy and its excellent performance in transmitting heavy loads.

Barbieri® Timing Belt Pulley with Taper Lock Bushing is an efficient and accurate connection solution for shaft fixed transmission. The core of the Taper sleeve keyless timing pulley lies in its expansion sleeve connection mechanism. The expansion sleeve is a ring-shaped part with a taper inside. When subjected to external force, its inner diameter will change, thus tightly holding the shaft. This connection method does not require keyway processing on the shaft, greatly reducing processing costs and installation time.
