AR41451 | RTX Pump Mounting Kit, Rail Hardware

AR41451 RTX Hydraulic Motor Mounting Kit | F51 Bell Housing and Flexible Coupling, 1 in. Shaft

The AR41451 is Annovi Reverberi’s F51 mounting kit for driving an RTX series pump with a hydraulic motor. It is a bell housing and flexible coupling that joins the pump to an SAE J744 B 2-bolt or 4-bolt hydraulic motor with a 1 in. (25.4 mm) shaft. The bell housing holds pump and motor in perfect alignment, and the flexible coupling absorbs start-up shock and small misalignment before it reaches the pump bearings.

It turns an RTX pump into a hydraulic-drive unit you can run off a truck, skid steer, excavator or any hydraulic power pack. Choose it over a close-coupled flange when your motor’s shaft does not match the pump directly, or when you want coupling protection on a unit that runs long hours.
