NTN株式会社　複合材料商品事業部 Company Overview

- Eliminates the need to confirm the rotation direction during assembly, reducing manufacturing costs for customers. - Demonstrates high quietness, low vibration, and low torque immediately after startup. In addition to eliminating the need to confirm the rotation direction during assembly, which was required for conventional fluid dynamic bearings, it excels in quietness, low vibration, and low torque compared to sintered oil-impregnated bearings (hereafter referred to as groove-less bearings) that do not have dynamic pressure grooves. This contributes to improved quietness and energy efficiency in small motors and actuators, as well as reducing manufacturing costs for customers.

This is a sliding screw that demonstrates excellent load-bearing capacity, durability, and heat dissipation through the integrated molding of aluminum alloy and a unique resin material.
