High load capacity</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">By optimizing the bearing&#39;s internal design, such as the use of larger diameter balls, the load capacity has been increased by 15% compared to conventional products&nbsp;*1&nbsp;enabling heavy-duty cutting.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">*1 NSK&#39;s current H-type Robust Series bearings (SUJ2 version)</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">2. High speed performance</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Optimization of internal specifications has realized high-speed performance equivalent to that of conventional products, enabling use in both low-speed and high-speed applications.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">3. Longer operating life</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Optimization of internal design and the use of NSK&#39;s proprietary long-life steel have resulted in service life up to six times longer than that of conventional products.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Other improvements in materials and manufacturing methods contribute to reduced carbon emissions and energy savings during manufacturing compared to the X-type ROBUSTDYNA bearings.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Product Benefits</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">The new J-type ROBUSTDYNA bearings extend service life and reduce machining time during heavy cutting, contributing to improved productivity and long-term stable operation of machine tools.</span></p><p><br/></p>
