Pulley Hub Cat. No. 00 0669 251 Agrosikora

Pulley hub in CLAAS combine harvester drive systems

A pulley hubis a mechanical component that enables permanent and stable mounting of a pulley on a shaft. In the case ofCLAAS combine harvesters, such as LEXION, TUCANO or MEGA, this hub is essential for the proper functioning of belt systems, ensuringeffective torque transmissionand maintaining axiality during operation. The model marked with catalogue number 00 0669 251 0 is used in many drive mechanisms, both main and auxiliary.

Where is the pulley hub located in the machine?

The pulley hub in a CLAAS combine harvestercan be mounted in several key areas of the machine. It is used inmain drives, where it is responsible for seating pulleys driving the threshing drum, fan, or straw walkers. Inauxiliary drivesit is mounted on the shafts of hydraulic pumps, alternators, and radiator fans. It also frequently plays a role invariators, as part of the variable ratio mechanism. Thanks to its design, it enables a stable and secure connection of the pulley to the shaft, often using a keyway or another mounting system.

The role and functions of the hub in the combine harvester design

The main role played by theCLAAS pulley hub, is the permanent mounting of the drive element on the shaft, allowing for precise and lossless power transmission. It providespulley centring, which is crucial for reducing vibration and noise, as well as for even wear of V-belts. Thanks to its solid construction and high resistance to loads,the CLAAS pulley hubcan operate under conditions of high torsional forces, typical of threshing-separating systems and auxiliary systems.

Combine harvester models compatible with this hub

The CLAAS pulley hubmarked with catalogue number 00 0669 251 0 is found in many combine harvester models of this brand. It can be found in series machinesLEXION– from version 400 to 700, depending on the drive configuration. AlsoTUCANO(300–500 series) and selected models ofMEGAandMEDIONcan be equipped with this element. To ensure compatibility, we recommend that you contact us.
