GRH-200-5G14-10-D-JA-S2

The GRH-200-5G14-10-D-JA-S2 motor is produced by Vickers in the Hydraulic Motors series and is intended to convert hydraulic energy into controlled rotary motion for automation circuits. Its displacement of 199.8 cm³ per revolution establishes the volume of fluid required for each turn and defines flow sizing. A continuous torque rating of 45 daNm allows the shaft to deliver steady output under constant load, while a continuous speed limit of 300 rpm keeps internal stresses within design margins. The minimum operating speed of 10 rpm supports slow-moving equipment that demands precise positioning, and a minimum starting torque of 41 daNm ensures reliable breakaway under load. Starting pressure with no external load is 5 bar, so low system pressure can begin rotation without cavitation. Continuous oil flow should not exceed 60 L/min to maintain efficient heat balance, and the maximum continuous pressure drop of 175 bar defines the allowable differential across the motor housing during sustained duty.

For brief overload conditions the motor accepts an intermittent speed of 375 rpm, giving machines the ability to accelerate temporarily without exceeding critical limits. An intermittent torque capability of 50 daNm covers short higher-load events, and a peak torque of 56 daNm handles momentary shock loads such as rapid starts or stops. Transient flow may rise to 75 L/min, matching the intermittent operating window, and the maximum intermittent pressure drop of 200 bar accommodates elevated differential pressure during these periods. A peak pressure drop of 225 bar is tolerated for very short surges that can arise from abrupt directional changes. Connection to the hydraulic circuit is through a G 1/4 BSPP port thread, which aligns with standard pipe fittings for compact lines. The assembled motor weighs 8.1 kg, a consideration when selecting mounting hardware and support structures.
