Atra-Flex M1 Hub 1.500 SS is a Millennium Non-Spacer Jaw Coupling Hub manufactured in stainless steel for a 1.500‑inch bore. This hub is part of the ATRA-FLEX family and is designed to be used with Millennium jaw coupling inserts in a non‑spacer configuration, helping transmit torque between shafts while accommodating minor misalignment. The stainless steel construction provides corrosion resistance and durability in demanding environments. Sized for a 1.5‑inch shaft, the M1 hub integrates with compatible hubs and inserts to create a modular coupling assembly that supports routine power transmission tasks in industrial drive systems.
