The selection of grease is also an important part of the production process of bearing manufacturers. If the grease of the bearing is not properly selected, it is easy to cause problems such as heat generation and excessive noise in the bearing, thereby reducing the service life of the bearing and affecting the performance of the spindle; Our bearing manufacturers will select the most suitable grease according to different application scenarios of customers, bearing load, speed, working temperature, etc.; too much grease injection to the bearing will reduce the bearing cavity, and the bearing is prone to heat during operation; too little grease injection , it may cause local oil-free friction, easily damage the raceway, and cause early failure; the standard bearing manufacturer will strictly control the amount of grease injected into the bearing, and will use a precision electronic scale to check after the grease is added. When injecting grease, advanced grease injection equipment will be preferred, which can ensure that the grease injection amount of the bearing is within the most reasonable range, and at the same time, the grease injection will be more uniform. The grease injection process should also be carried out in a dust-free environment as much as possible; the torque is accurate, and the rotation can be stable!
