Product Description

External circulation large load screw FDDW

External circulation large load screw High precision intubation screw The cannula screw is a linear transmission element widely used in precision machinery, automation equipment and industrial control systems. With its high precision, high load-bearing capacity and stability, the cannula screw can provide smooth and reliable motion control in harsh industrial environments. It adopts a unique structural design, which effectively reduces the transmission error and provides a smoother running trajectory.

The cannula screws we provide have a variety of specifications and models, which can be customized according to customer needs. They are widely used in CNC machine tools, robot systems, automated production lines and other fields to meet the requirements of various equipment for precision transmission and high load support.

External circulation large load screw High precision intubation screw

1.Structure and specialties
Unprocessed products at the end of the shaft are produced by standardizing the screw shaft of precision ball screws and process.ing it into a series of mass-produced products of specified length. The screw shaft end is easy to be machined.In addition, there are single nut FDW type and double nut FDDw type nut models. Please choose the appropriate type accordingto the purpose of use.
2.dustproof
When dirt or other foreign obiects may enter the ball screw, a dust-proof device (such as a telescopic cover, etc, must be used to completely cover the screw shaft.
3.lubrication
For nuts, lithium soap based lubricating oil has been sealed at the time of delivery.
4.Additional processing of the screw shaft end
Due to the fact that only the efective threaded portion of the screw shaft is surface hardened through induction hardening or carburizing treatment,it is very easy to perform additional machining on the shaft end through a grinder or milling machine.In addition, as both ends of the screw shaft have central holes, they can accept external cylindrical grinding processing.
Surface hardness of effective threads:58 to 64HRC
Surface hardness of the end of the screw shaft
FDW.FDDWmodel:22 t0 27HRC
