Tsubakimoto Chain has launched its LN Series of Jaw-Flex coupling to the European market. The high-precision coupling is specifically designed for use with servomotor drives such as those on machine tool feed shafts. Featuring vibration damping characteristics, and a simple design which makes installation extremely easy, the new range is suitable for OEM and maintenance requirements alike.

Derek Mack, sales director for Tsubaki U.K., comments: “Tsubaki is dedicated to manufacturing power transmission solutions for its customers that will improve productivity and offer industry leading reliability. The LN Series offers a choice of materials to suit specific requirements and a design which is designed to provide excellent shock absorbing qualities and superior vibration damping; both of which improve overall machine performance."

The coupling consists of two hubs, which use a simple clamping design to locate onto the drive shaft, and a spider which is available in two different materials types depending on the application. End-users can specify between material type 98A, which features excellent vibration damping, or 64D, which offers rigidity and high wear resistance. Currently there are six couplings available in the LN Series range with the ability to deliver a torque transmission range of 60 Nm to 405 Nm and accommodate shaft diameters from 12 mm to 42 mm. In applications where precision and reliability is key, such as robotic servomotor control and machine tool applications, the LN Series offers the key characteristics required within these and similar applications.
