Various mechanical equipment due to different design and working conditions, put forward different requirements for lubricating grease. The basic requirements for selecting lubricating grease are as follows for your reference.
On June 6, the Gongzhuling Entrepreneur Association of Jilin Province facilitated the marriage between state-owned enterprises and private enterprises, and Jilin Gongzhuling Bearing Company and TECO Industrial Park reached a comprehensive cooperation intention.
Bearings are the key basic parts of the equipment manufacturing industry, at present, the performance and quality level of rolling bearings produced in China are generally not high, and most of the high-grade bearings rely on imports. With the rapid development of rail transit equipment industry, the demand for high-grade bearings has increased sharply. EMU bearings with a speed of more than 200 kilometers per hour, bearings with axles heavier than 30 tons of heavy-duty railway wagons, and new urban rail transit bearings with a service life of more than 200 million kilometers.
1. Deep groove ball bearingThis is the most popular of all ball bearing types, which is widely used in a variety of sealing rings, shields and stop ring devices. It can withstand radial loads, bidirectional axial loads, and their synthetic loads. Various combinations can be implemented according to user needs, with different tolerance classes and different low noise groups.
1. No oil lubrication or less oil lubrication, suitable for places where oil cannot be refueled or it is difficult to refuel, and can be used without maintenance or less maintenance; 2. Good wear resistance, small friction coefficient and long service life; 3. There is an appropriate amount of elastic plasticity, which can distribute the stress on a wide contact surface and improve the bearing capacity; 4. The static friction coefficient is similar, which can eliminate crawling at low speed, so as to ensure the working accuracy of the machine; 5. It can reduce vibration, reduce noise and prevent pollution of machinery;
