[
Labor Savings/Time Reduction] This compares the installation times of friction-type fasteners using the mechanical (wedge) method (PSL-G) and the hydraulic method (ETP-E Plus, ETP-T). When
fastening a shaft to a hub
, the wedge-type friction fastener takes approximately 3 minutes, whereas the hydraulic-type friction fastener enables high-precision fastening of the shaft and hub in about 20 seconds.
Concentricity is 0.02 mm for the ETP-E Plus and 0.006 mm for the ETP-T.
Furthermore, since anyone can secure the connection with a single bolt, no specialized skills are required. Introducing
hydraulic friction fasteners to areas requiring frequent disassembly can result in significant labor savings.

[Labor Savings/Time Reduction
] Watch the video to see how to install our friction-type fasteners with the hydraulic system (ETP-E Plus, ETP-T). Even new workers
without specialized skills can achieve a high degree of concentricity and precision with no shaft runout simply by tightening a single bolt. Using these fasteners in applications
that require repeated installation and removal can lead to dramatic labor savings.

[Long Service Life / Maintenance-Free] Watch this video to
see examples of how the Rosta (oscillation, vibration damping, and cushioning device) is used. Based on real-world
examples of chain drives, V-belt drives, and timing belt/flat belt drives, this video showcases how the Rosta functions as a fixed tensioner.

[Space-Saving Design] Generally
, vertically driven ball screws require a mechanism for stopping and holding the load. In such
cases, unless a servo motor with a built-in brake is selected, a separately mounted, non-excitation-type brake must be installed in addition to the drive source.By forming the rotor
hub of our BXR non-excitation-type brake (spline hub type) to match the outer diameter of the Servoflex metal plate spring coupling (SFF model), we achieve greater space savings compared to conventional brake mounting methods, enabling a more compact overall system design.

The Servoflex SFR is a high-damping rubber coupling designed for servo and stepper motors. Its newly developed
rubber elements provide high damping and low reaction forces. Compared to flexible couplings that use metal in their elastic sections, it absorbs vibrations more quickly. This helps suppress resonance phenomena that are a concern with stepper motors and similar applications
.

[Resolution of Resonance Issues] We offer solutions for vibrations that occur when servo motors are operating
at high gain.

[Resonance Countermeasures] We offer solutions for vibrations
caused by stepping motor pulsations.

[Wall-Separated Transmission / Hygienic] This is a non-contact coupling that utilizes magnetic force
. Thanks to the action of magnets, power can be transmitted even through a wall, and the coupling can be easily attached, detached, and aligned. Furthermore, since there is no wear, dust generation, noise, or vibration, it is suitable for use in cleanrooms and similar environments.

This guide explains how to install the product while mounting it onto a shaft.

This video demonstrates how to install our Servoflex SFS-S metal plate spring coupling with a friction-lock hub. This procedure requires
that the product be pre-assembled and that the two shafts to be connected have already been aligned.

This video demonstrates how to install our non-excitation-type brakes. In
this example, the brakes are mounted on a ball screw unit to maintain position during power outages and similar situations. The video covers both installation methods: the "stator mounting" method, where the stator—which contains the coil that generates heat
—is attached to the equipment, and the "plate mounting" method, where the stator is not attached to the equipment but is instead mounted on a plate on the opposite side.

This video explains how to install our electromagnetic two-clutch system. You can also see the
parts required for installation.

This video demonstrates how electromagnetic clutches and brakes—which are primarily used in industrial applications—work.
In particular, while it can be difficult to visualize how electromagnetic clutches operate and what their role is, this video allows you to see how they actually move using a real-life example.
