NTN Corporation (hereafter, NTN) exhibits at “China CNC Machine Tool Fair 2024 (CCMT 2024)” held from April 8 to 12, in Shanghai, China.
This event is one of the largest machine tools exhibitions in China and held for the first time in six years after the COVID-19 pandemic. More than 2,000 companies of machine tools manufacturers and related manufacturers around the world will exhibit at the event. At the time of the previous event in 2018, approximately 170,000 people visited the event and exhibiters showed the latest manufacturing technologies including various machine tools, industrial robots, and automation facilities.
In China, which has one of the world's largest machine tools market, the highly functional models with high productivity, maintainability, and saving energy are developed and used more, and industrial robots are introduced to automate manufacturing activities and save labor.
NTN will exhibit at this event under the theme of “Navigate your future -NTN ULTAGE-.” We will introduce wide range of products that contribute to solving a variety of machine tools issues and enhancing the functionality of robots.
As the “ULTAGE Series*1” of precision roller bearings for machine tools, we will exhibit the “Angular Contact Ball Bearing for High-Speed and Heavy-Cutting Machine Tools” that achieves both high-speed rotational performance and load capacity. Additionally, we will introduce the “Machine Tool Main Spindle Bearing with Air Cooling Spacer” that achieves the world's highest level in high-speed rotational performance while ensuring higher rigidity by using air cooling spacers that use our proprietary air-cooling technology, and the technology to detect bearing abnormalities such as “Sensor Integrated Bearing Unit” for Machine Tool Spindles which contributes to preventing bearing seizure by monitoring the condition with sensors built into the outer ring spacer.
As for products for robots, we will exhibit bearings for robot gearboxes and “Multi Track Magnetic Encoder Integrated Rolling Bearing” which contributes to the detection of the absolute angle and downsizing/lightweighting of robot joints through the integration of bearings and magnetic encoder.
We look forward to seeing you at the event.
- ULTAGE is the name for NTN's goal of achieving the ultimate performance with precision bearings, and expresses the “Ultimate” performance on any type of “Stage.”
Main exhibits
“Angular Contact Ball Bearing for High-Speed and Heavy-Cutting Machine Tools”
This product has a high-speed rotational performance of dmn value of 1.6 million as well as 30 % improved allowable axial load capacity compared to NTN's conventional products. This enables a single machine tool to cover the rough machining work and finishing processes that previously required numerous machine tools. It also helps to further increase productivity of machining centers and complex processing units.
“Machine Tool Main Spindle Bearing with Air Cooling Spacer”
By applying air cooling spacer with NTN's proprietary air-cooling technology to bearing for main spindles of machine tools, it ensures high rigidity of the main shafts, while also achieving the world's highest standard of high-speed rotational performance. There are product lineups with grease lubrication and air-oil lubrication for customers to select the most suitable bearing specifications according to the usage conditions.
“Sensor Integrated Bearing Unit” for Machine Tool Spindles
This product contributes to preventing seizing of bearings for spindles by advanced condition monitoring near bearing raceway surface with sensors built into the outer ring spacer.
By integrating two devices, an electro-magnetic generator that generates electricity using the rotation of spindle and a radio device, we deleted the external connection cables, and wiring space. The load detection sensor to detect bearing loads and their trends contributes to improved machining quality and productivity, and it also enables adjustments to mount bearings in a short time.
“Multi Track Magnetic Encoder Integrated Rolling Bearing”
This is a unit product integrating bearing with magnetic type encoder. By reading changes in magnetic poles of “Multi Track Magnetic Ring” attached to inner ring of bearing with magnetic sensor IC equipped with outer ring, it can detect rotational speed, direction, and absolute angle. This magnetic encoder has industry's highest level of angle detection resolution (maximum 20bit, resolution of approximately 0.00034°), and can be used in conditions with dust and oil.
