Reliability single row cylindrical roller bearing
2019-11-06 11:28:21
Linear guideway is widely used in semiconductor and liquid crystal manufacturing devices, automobile manufacturing equipment, handling robots, machine tools and other production equipment based fields. With the increasing demand for the reliability of mechanical equipment in the market, new requirements are put forward for the long life of linear guide. In order to meet the market demand, NH and NS series linear guides with high reliability are designed and developed by optimizing the pressure distribution on the contact surface between the rolling element (ball) and the guide groove.

Single row cylindrical roller bearings for machine tool spindles
2019-09-02 11:31:27
The single row cylindrical roller bearing is the key component of the spindle of the machining center. In order to achieve the best distribution of grease in the bearing during grease lubrication, it is necessary to run in for a long time and become the bottleneck to improve production efficiency. In addition, under the condition of oil air lubrication * 1, the bearing temperature rise is too high during low speed operation, which is also an urgent problem to be solved. To solve this problem, although the roller guide mode can be used to stabilize the cage position, it is easy to cause early damage to the cage under excessive load. Therefore, the outer ring guide mode is generally used in the industry.

By optimizing the internal design of the bearing, such as the use of larger diameter balls, the bearing capacity is increased by 15% compared with traditional products, and the fatigue life (dynamic load rating) is extended by three times * 1. This makes heavy cutting possible and reduces processing time.

Improve automobile power and fuel consumption. In a 2-speed variable speed EV with excellent performance and high efficiency, large gear ratio difference can be achieved by using this product to solve shift impact, and 7% power consumption can be improved * 2. At the same time, in the belt CVT, the energy loss of the gearbox can be reduced by reducing the oil pressure to compress the steel belt, and 1.05% of the oil consumption can be improved * 2.
