<p style="text-align: center;"><img src="/ueditor/php/upload/image/20231212/1702387841111783.png" title="1702387841111783.png" alt="1.png"/></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">NSK has developed HTF-SRM Ball Screws, a high-speed, heat-resistant version of its high-load drive ball screws, ideal for high-cycle, thin-wall molding in electric injection molding machines.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">NSK is exhibiting this product at the IPF Japan 2024 International Plastics Fair and plans to begin accepting orders in April 2024, with a global rollout to follow. NSK aims to achieve annual sales of 500 million yen by fiscal 2026 for this product.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">The newly developed SRM (Smooth Return Metal coupling) recirculation system and heat-resistant components achieve the industry&#39;s highest level of operating speed and heat resistance. The permissible d-n value1 is 200,000, a 40 percent improvement over NSK&#39;s conventional high-speed HTF-SRC ball screws. The maximum operating temperature is 90°C and momentary maximum temperature is 100°C, both of which are 20°C higher than NSK&#39;s conventional products.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">The external dimensions of the screw and nut are the same as those of the HTF-SRC model, eliminating the need for design changes when upgrading.</span></p><p><br/></p>
