The Rexroth FDM-E-S is a flange-type double-nut ball screw nut, belonging to the standard series (E series), used in precision positioning and transmission applications. Its core features are C4/C5 preload rating, built-in seal, and Rexroth standard flange connection dimensions.
FDM-E-S Nut Basic Structure and Characteristics:
Structure: Integrated design of double nut + flange, preloaded with gaskets to eliminate backlash and improve rigidity; uses internal ball circulation for smooth operation and low noise.
Sealing Configuration: Built-in standard dustproof seal effectively prevents dust ingress, suitable for industrial environments.
Lubrication Design: Lubrication port in the center of the flange;
Key limitations: Supplied only as a complete ball screw assembly; nuts are not sold separately; avoid collision with the front lubrication unit during installation.
Rexroth ball screw drive systems are successfully used in a variety of fields: Machine tools, Forming equipment, Automation and material handling, Woodworking, Electrical and electronics, Printing and papermaking, Injection molding machines, Food and packaging industries, Medical equipment, Textile industry, and others.
