Rotaro forks are fundamental components for the assembly and proper functioning of cardan shafts on agricultural machinery. Produced with high-quality and precision materials, these forks ensure a robust and secure coupling between the cardan shaft and the power take-offs of tractors and implements. Their resistance to torsional and tensile stresses is crucial to prevent failures and premature wear. Using original Rotaro forks ensures perfect compatibility and reliable power transmission, helping to maintain the overall efficiency of the machine and extend the service life of the entire drive system.
Rotaro overload clutches (or torque limiters) are essential safety devices designed to be installed directly on the cardan shafts of agricultural machines particularly exposed to torque spikes. These components act as an automatic disengagement mechanism: when the transmitted torsional force exceeds a preset limit, the clutch slips or temporarily disconnects the transmission. This critically protects the internal components of the implement and the tractor from costly damage such as broken gears, chains, or axles. We offer a full range of Rotaro clutches, including pawl, friction disc, or shear bolt versions, to suit every type of implement (balers, shredders, ploughs). Invest in the safety and longevity of your machinery with an original Rotaro overload clutch.
Rotaro standard cross joints (or cardan crosses) are fundamental components of any agricultural drive shaft. They act as the flexible joint that allows the shaft to transmit rotational motion even when the angle between the tractor and the implement varies. These cross joints are designed to withstand the stresses, radial loads, and constant wear typical of agricultural work. Using original Rotaro cross joints guarantees maximum dimensional precision, reducing vibrations and preventing overheating and premature failure of the entire cardan shaft. Keeping the cross joints regularly lubricated is essential for their longevity and the overall efficiency of the machine.
