» Mechanical actuated power take-off units.
Available in sizes up to 533 mm (SAE 21), these mechanical PTOs are ideal for many basic actuation installations. Remotely actuated versions are available for safer, easier operation and greater equipment design flexibility. Download the new selection guide, special units, selection process, ordering codes, duty classifications, allowable side loads and other information to specify the correct model of mechanical PTO for your application.

» Hydraulic actuated power take-off units.
Available in side-load straddle-bearing clutched models, in-line clutched and non-clutched models. For similar applications as the mechanical PTOs. Hydraulic clutches can be used wherever a disconnect is required between driven equipment and the prime mover.

» Pump drives
Available in a wide variety of gear ratios, including speed increasing and reducing configurations. These pump drives are of modular design creating a choice of several input options, including a rubber block drive or clutch to match SAE engine flywheel dimensions. Can be independently mounted directly or with a clutch. SAE and non-SAE adaptor kits available.

» Gearboxes
RM version gearboxes are specifically designed for close coupling to industrial diesel engines and are available in either speed increasing or speed reducing format. Gearboxes can be supplied with output shaft either same or opposite rotation to input shaft. Input to the gearbox can be made either by rigid/flexible coupling or via a 'BD' series clutch.

» Clutches
BD series clutch for close couple to diesel engines with SAE style flywheel facility. Designed to mount onto any engine with flywheel and bellhousing conforming to SAE dimensions. These clutches consist of an over-centre clutch assembly mounted onto a tapered shaft carried on two bearings. Mechanically actuated.

BDS series clutch for independent, in-line arrangements, capable of accepting high radial loads and transmitting powers of up to 850 kW as standard. Versions are also available to close couple hydraulic pumps to the clutch output shaft.

Oil Bath Clutches are free standing, particularly suited to arduous applications and are capable of withstanding high radial loads.

» Pneumatic actuated clutches
Available in sizes up to 1067 mm (42") designed to provide maximum dependability and lowest installation and operating costs. These air clutches are available in triple, double or single plate construction.
