The power steering pump FN4 provides the amount of oil needed for operation of hydraulic steering systems in commercial vehicles at all times. The pump is designed primarily for connection to the compressed-air compressor or the power take-off on an engine. The shaft connects by means of a cross-slotted disk or splines. The pump can be driven by either a gear or belt. For these cases, an anti-friction bearing is used for the drive shaft. The ball bearing needed for the above instances can be incorporated into the housing. In addition, an oil reservoir can be mounted directly to the pump. This eliminates the hose and assembly costs at the vehicle manufacturer.
The proven design ensures a reliable supply of oil to the steering system.
