Coupling D40-66-18-22

WERB Flexible CNC Coupling D40-66-18-22 | Shaft Coupler for 18 mm and 22 mm Shafts

The WERB flexible CNC coupling D40-66-18-22 is designed to connect stepper or servo motors to ball screws using 18 mm and 22 mm shafts. Its flexible body helps compensate for small misalignment and reduces vibration, improving the life of bearings and screws on CNC and automation equipment in Pakistan. As the trusted WERB distributor, supplies original D40-66-18-22 couplings with ready stock and competitive pricing.

Key Features

Flexible WERB shaft coupling with 40 mm diameter and 66 mm length for medium-size CNC axes. The precision-cut flexible section transmits torque while allowing limited angular and parallel misalignment between motor and ball screw. Clamping hubs on both sides provide a secure, backlash-reduced connection to 18 mm and 22 mm shafts.

Technical Specifications

Coupling D40-66-18-22 is machined from quality metal with accurately bored 18 mm and 22 mm shaft holes. The spiral or slot pattern in the body provides flexibility without sacrificing strength, making it suitable for typical CNC speeds and loads. When installed on aligned shafts, it offers smooth running and reduced noise on CNC routers and automation lines in Pakistan.

Industrial Applications

Used on CNC routers, milling machines, engraving machines, and automation axes where motors with 18 mm shafts are coupled to ball screws or drive shafts with 22 mm ends. Popular with OEMs and retrofitters in Lahore, Karachi, Faisalabad, and other industrial areas using WERB flexible couplings for reliable power transmission.
