| NACHI new series automatic self-aligning roller bearing on the market |
| Release Time： 2016/3/14 Hits：1292 |
NACHI bearings, NACHI import bearings company as from the materials and components to the production practice through comprehensive machinery maker, constantly develop and sell high uniqueness ball screw support bearings, thin-walled bearings etc powerful industrial machinery bearings.
Automatically self-aligning roller bearings mainly reducer and steel equipment as the center, has the world's highest level of high load capacity, has received the high praise, and in the domestic market share reached 20%.
This time, the company product line for automatic self-aligning roller bearing new two series of products, industrial machinery at home and abroad to meet the market demand for high-performance, to further expand market share at the same time.
2. New product profile ・ automatically self-aligning roller bearing "EXQ series" EXQ シ リ ー ズ (1) the target market Paper making, steel equipment, construction/agriculture/mining machinery, reducer, etc All the industrial machinery sector (2) the market demand Through automatic spherical roller bearings are of spherical shape rail and the roller, make its have so compared to other bearing load capacity is bigger, and easy to use, so has been applied in a wide range of industrial machinery field. In recent years, under the background of high performance processing for industrial machinery, to cope with higher axial load (does) and the increasing demand of high speed rotation. This time, the company in order to meet the requirements of high load, high speed in the field of industry machine, to market the automatic self-aligning roller bearing "EXQ series". (3) characteristics
A. the axial load resistance improved By optimizing the internal shape, axial load resistance compared with the previous products increased by 25%. Achieved in the past is difficult to use automatic self-aligning roller bearing used in the field of high load. B. allow rotation speed increase Roller rotation by stable condition, reduce the bearing heating, achieved the world's highest level to allow rotation speed, increased by about 10% compared with the previous products, so as to meet the requirement in high speed and efficiency of industrial machinery, contributed a lot to improve productivity. C. can withstand 200 ° c On the basis of thermal stabilization process, make its can be under the environment of high temperature (200 ° C). D. high impact resistance performance Set bearing retainer improve the impact resistance performance of "EXQ - V specification", make its can be used in mining machinery and other harsh environment. (4) product line
Bearing outside diameter from 52 mm to 280 mm, 109 models.
Does axial load (load) refers to In parallel to the axis of rotation of the bearing load. Also known as the thrust load. (supplement) In the large mechanical equipment and other general industrial machinery, due to large shaft bending, and from the Angle of structure prone to installation error, and automatically self-aligning roller bearings can not only withstand a load of perpendicular to the axis of rotation (radial load), still can carry axial load, so the more widely used in the field. ・ thrust self-aligning roller bearing automatically "EXS1 series" EXS1 series (1) the target market Centering on the injection molding machine industry machinery (2) the market demand Automatic thrust self-aligning roller bearings used in injection molding machine, vertical pump, Marine department as well as spiral under high axial load. Injection molding machine, along with the electric drive mode, less electricity, reduce environmental load, maintenance-free got continuous development, at the same time, in recent years, in order to improve the productivity as the target of high speed and the trend of accelerated sharply slowing faster. This time, the company in order to adapt to high speed injection molding machine brought by the electric and maintenance-free, launched to the market is suitable for the automatic grease lubrication thrust spherical roller bearings "EXS1 series" products. (3) characteristics
A. allow rotation speed increase By shape optimization, the surface treatment of bearing retainer and improve precision of the roller end, rotates sharply reduced resistance, at the same time, by raising the temperature of a low, realized increases by about 30% compared with the previous products allow rotation speed to the top ranks of the world, so as to adapt to the high speed injection molding machine, etc. B. adapt the grease lubrication By optimizing the bearing to keep the shape of a form, in stable rotates at the same time, make to the guide bearing retainer grease supply more smoothly, so as to realize low temperature. As a result, will no longer need to oil supply device, and contributing to the environmental protection and free of maintenance. C. long life By optimizing the internal and external wheel track and roller shape, make the interface stress homogenization. Even in a high cycle using environment, can also realize product about 2 times of long life. (4) product line
Bearing outside diameter from 130 mm to 320 mm, with 14 models. |
