Cross roller bearing, as a kind  FAG Bearing  of precision bearing with special structure. During its storage and need special care. Only in the right environment to the biggest keep cross roller bearing accuracy and quality. A, cross roller bearing should be stored in clean, dry environment, in the handling and storage control temperature, humidity, temperature and humidity to fixed in an acceptable range, should leave the ground more than 30 cm. Second, the part of the bearing has certain storage life. For example, dust cover and bearing oil seal, when stored for a period of time, bearing will be a new start torque of bearing, at the same time, due to long time storage after the lubrication performance of the grease will be destroyed, so the bearing should be regularly check table maintenance. Three, to ensure the bearing can be normal, reliable operation, it is necessary to impose enough lubrication, in order to prevent the rolling element and raceway and there is a direct metal contact between cage, causing wear and bearing surface corrosion. Therefore, in a variety of applications, select the appropriate lubricants and lubrication is very important, at the same time, also need the correct maintenance. Four, lubricants mainly based on the operation condition of actual choice, namely: the temperature range and speed as well as the surrounding environmental impact. If can guarantee reliable lubrication, the bearing lubricant used dose the hours, the lowest operating temperature, but at the same time other role, such as seal or heat dissipation, consumption will increase. So when installing a bearing, filling grease to bearing the remaining space filled with general control bearing box the remaining space of 1/3-1/2, much more susceptible to high temperature. YRT turntable bearing because of the characteristics of low speed and high rigidity, used as a lubricant, grease filling at a time using 1 ~ 2 years, has the characteristics of convenient maintenance. Because of the roller for cross array, so only 1 set of cross roller bearing ring can bear the load of every direction, compared with the traditional model, rigid 3 ~ 4 times. At the same time, because of the cross roller bearing inner ring or outer ring is two integral structure, bearing clearance can be adjusted, even if be preloading, also can get high precision rotary motion. When making new spindle design, the choice before cross roller bearing, consider performance parameters of the spindle, roughly determine the performance of the key, then enter the further exploration. (including: the spindle speed, spindle precision of the spindle rigidity, life of the spindle, spindle fever, spindle reliability) Determines the main parameters, the meter spindle's actual size (diameter of axle, length, bearing span). According to the bearing form (ball or roller bearing), go (to match the number of columns), drive mode (belt) within, gears, motors, motor, lubrication, grease, oil and gas, oil mist, spray) set of parameters such as spindle to determine its structure.
