NTN Exhibits at the 15th China International Machine Tool Show “CIMT 2017”

Release Time：01 Apr,2017

Date April 17 (Mon) to 22 (Sat), 2017 Venue China International Exhibition Centre (New Venue) Beijing, China Booth No. E3-702 NTN will run a booth at the 15th China International Machine Tool Show “CIMT 2017.” Exhibits such as products and technology for machine tools will be shown that include the precision roller bearings for machine tools ULTAGE* series products under the theme of “Navigate your future-NTN ULTAGE.” We will be introducing the characteristic function and construction of the machine tool main spindle small high speed angular contact ball bearings and the machine tool main spindle bearing with air cooling spacer from the ULTAGE series of products in addition to providing an explanation using video of the mechanism and features of products such as how base oil is supplied to the eco-friendly air-oil lubricated bearing. Furthermore, visitors will be able to experience the chain of flow for the bearing technical calculation system for machine tool spindles by inputting data at a computer and then obtaining the results in a short time. In addition, we will also introduce NTN's proprietary technology such as sliding material exclusive for machine tools from composite material products. We look forward to seeing you at the event. * ULTAGE is the name for NTN's new generation of the world's highest standard of bearing series, and expresses the “ULTIMATE” performance on any type of “STAGE.” Main exhibits ULTAGE Series of Precision Roller Bearings for Machine Tools Precision bearings that support high efficiency processing, high reliability, high quality processing and environment-conscious design required for machine tools. Demonstrates excellent ability due to such factors as the adoption of seals on both sides, special grease, special material/surface modification and also the optimization made to the internal bearing design. <img src="http://www.bearing.com.cn/RecommendedCompany/guojiApr1-4.jpg"> ULTAGE Small Size High Speed Angular Contact Ball Bearing for Machine Tool Spindles Adopts a newly designed seal that retains a large volume of grease inside the bearing, without obstructing dust prevention functionality and cooling with compressed air, to improve grease retention and ensure the steady flow of compressed air. In addition, we have devised a grease lubricated position and volume, which achieves long life. Furthermore, by adopting a processing method that improves the precision of the bearing raceway surface, we have reduced vibrations by approximately 50% in comparison with conventional types. <img src="http://www.bearing.com.cn/RecommendedCompany/guojiApr1-5.jpg"> Machine Tool Main Spindle Bearing with Air Cooling Spacer Reduces the inner and outer ring temperature difference during high speed rotation by adopting an “air cooling spacer” that applies a unique air cooling technology to the machine tool main spindle bearing. This improves the high speed rotational performance by 20% in comparison with existing parts (ultra-high speed angular contact ball bearings) and achieves a dmn value* of 2.1 million with air oil lubrication and fixed position preload, which provides the highest level of high-speed rotational performance in the world. * An indicator that expresses the rotational performance of bearings and is bearing pitch circle diameter (mm) × rotational speed (min-1) <img src="http://www.bearing.com.cn/RecommendedCompany/guojiApr1-6.jpg"> “High Speed Angular Contact Ball Bearings HSE-NEW T2 Type” for Machine Tool Main Spindles Achieves a dmn value of 1.6 million, which is an improvement of up to 50% for high-speed rotational performance in comparison with existing parts due to reviewing the retainer pocket shape and resin material. Polyamide resin retainers can also be applied to high-speed rotational regions where phenol resin retainers were adopted. <img src="http://www.bearing.com.cn/RecommendedCompany/guojiApr1-7.jpg"> Bearing Technical Calculation System for Machine Tool Spindles A system that customers can use to automatically calculate factors such as the main spindle rigidity and bearing operating life for precision roller bearings in a short amount of time. The main spindle layout has been increased from 10 to 13 patterns and the security level has also been improved. Contributes towards further reducing development lead times for machine tools. <img src="http://www.bearing.com.cn/RecommendedCompany/guojiApr1-8.jpg">
