Flexible Plum Coupler For stepper motor

Description

D20L25 Flexible Plum Coupler – Precision Shaft Coupling for CNC Stepper Motors

This D20L25 flexible plum coupler is designed to connect stepper motors to lead screws, ball screws, and other drive components with precision and reliability. Featuring a plum-shaped elastic spider, this shaft coupling effectively dampens vibration, compensates for minor misalignment, and reduces backlash during operation.

With a 20mm diameter and 25mm length, the D20L25 is a compact yet durable solution for tight spaces. The aluminum alloy body keeps weight low while maintaining strength, and the 2.5Nm torque rating handles the demands of most desktop CNC routers, 3D printers, and automation projects.

Available with 5mm to 8mm bore options, this plum coupler fits common NEMA17 and NEMA23 stepper motor shafts. The flexible spider insert absorbs shock loads and electrical isolation, protecting your motor and drive train from wear.

Ideal for CNC stepper motor applications, this flexible shaft coupling is easy to install with standard set screws and requires no lubrication. Whether you’re building a new CNC machine or replacing a worn coupling, the D20L25 offers a reliable, cost-effective solution.
