Mechanical clutches are essential components in hydraulic power transmission systems, designed to safely engage and disengage drive shafts and hydraulic pumps. These devices control the start and stop of hydraulic flow while reducing energy losses and eliminating friction-related power losses. They are widely used in both mobile and stationary applications, playing a crucial role in power take-offs (PTOs), agricultural machinery, municipal vehicles, earthmoving equipment, and industrial hydraulic power units where selective mechanical engagement of the hydraulic pump is required.
The available range features face-tooth clutch designs that ensure rigid engagement and a high-strength positive mechanical lock. For systems requiring connections between smaller pumps and motors, the Borelli 50 daNm Electromagnetic Clutch – 30940/SF / 30941/SF Series provides precise engagement and an extremely compact configuration. For higher torque requirements, the Borelli Face-Tooth Mechanical Clutch Gr. 2-3 Series 30300 is the ideal choice for intermediate applications operating under continuous duty cycles. Finally, for heavy-duty systems and larger displacement pumps, the Borelli Face-Tooth Mechanical Clutch Gr. 3-5-4 Series 30500 ensures maximum reliability in withstanding high torsional stresses under demanding operating conditions.
The design of these series helps prevent premature coupling wear and ensures optimal alignment of the transmission system. By significantly reducing radial loads on pump bearings, the installation of these components considerably extends the service life of the entire hydraulic drivetrain, ensuring operational efficiency, completely slip-free power transmission, and maximum safety even under high starting loads.
