MIKI PULLEY (THAI) CO., LTD.

Baumannflex (metal coil spring coupling) MM (Thailand Miki Pulley)

The Baumann Flex Coupling MM is a compact coupling capable of high torque transmission, achieved through its three-layer metal coil spring structure. This model offers two types that can be selected according to the operating environment. There is a type that uses SUM24L equivalent material for the hub and piano wire for the coil spring (MM-K type), and a type that uses stainless steel for both the hub and coil spring materials to improve corrosion resistance (MM-K-S type). This allows it to maintain high durability even in harsh environments and accommodate diverse applications such as printing machinery, bookbinding machinery, woodworking machinery, and semiconductor manufacturing equipment.
■ Features
