Application: F12-150 Piston Motor

     A massive circular saw mounted out on the end of an excavator’s boom is a handy devise to have, if you need to clear a forest of its trees. But, how do you drive such a creation? It needs to be relatively light weight so it can be manipulated with a high degree of agility and it needs to be rugged. These saws experience sudden load changes and must operate in extreme temperature variations. A hydraulic motor drive is the answer. The Parker F12-150 is ideal for this application. It is a package of just 14 inch cube and can deliver 350 horsepower at 3,200 RPM. This motor has a unique piston locking, timing gear and bearing set-up, as well as a limited number of parts, adding up to a very robust design with long service life and, above all, proven reliability. This timing gear design synchronizes shaft and cylinder barrel, making the F12 very tolerant to high 'G' forces and torsional vibrations. It also has laminated piston rings which offer important advantages such as unbeatable efficiency and thermal shock resistance. Heavy duty roller bearings permit substantial external axial and radial shaft loads; so, a drive gear can be mounted directly to the motors output shaft, saving space and complexity.
