Cross-roller bearings are high-precision special-purpose bearings for rotary table applications. They have an irreplaceable role in mechanical equipment. It is because of its particularity that it is in the bearing

The choice must be more careful. Luoyang Hongyuan Bearings is the most professional manufacturer of cross-cylindrical roller bearings. We introduce our customers when selecting cross-roller bearings for use in turntables.

In order to select the most suitable cross roller bearing for customers. When selecting cross-roller bearings for turrets, we must consider factors such as bearing load, clearance, eccentric load, and speed, etc.

Cross roller bearing selection must be strictly controlled conditions in order to achieve the most satisfactory results.

First, the bearing installation space

       Due to the importance of the rigidity and strength of the shaft when designing the shafting system, the shaft diameter is generally determined first, that is, the bearing inner diameter. The cross roller bearing itself has mounting holes and oil holes so no such auxiliary mechanism is needed, and the installation space of the cross roller bearing is much smaller than that of the two or more sets of combined bearing solutions.

Second, bearing bearing

       Bearing size, direction and properties: The bearing load capacity is expressed in terms of the basic rated load, such as the size of the load, whether there is only a radial load, whether the axial load is unidirectional or bidirectional, the degree of vibration or impact, and so on. After considering these factors, choose the most suitable cross roller bearing type.

Three, speed

        The type of bearing that can adapt to the limit rotation speed: The limit value of the bearing rotation speed is indicated by the limit rotation speed, and its value is contained in the bearing size table. The limit rotation speed of the bearing is not only taken from the bearing type but also limited to the bearing size, cage type, accuracy level, and load condition. And lubrication methods, etc. Therefore, these factors must be considered when selecting.

Fourth, the rotation accuracy

        Types of bearings with the required rotation accuracy: The dimensional accuracy and rotation accuracy of the bearings have been standardized by GB according to the bearing type. The spindle, combustion turbine and control machine of the machine require high rotation accuracy, high rotation speed and low friction, respectively. In this case, P5 should be used. Accuracy above the bearing. Luoyang Hongyuan bearing cross-roller bearing precision has exceeded P4 level individual has reached the P2 level standard, basically meet the rotating requirements of various types of precision equipment.

Fifth, rigidity

        Cross-roller bearings that can meet the required rigidity of the mechanical shaft system: When the load is applied, the contact portions of the rolling elements and the raceway are elastically deformed. “High rigidity” means that the amount of deformation of this elastic deformation is small, and the stiffness of the bearing must be increased while the rigidity of the shaft is increased in the parts such as the rotary table of the machine tool, industrial robots, and measurement equipment. Roller bearings bear less deformation than ball bearings. Cross roller bearings use cylindrical rollers as rolling elements to ensure bearing rigidity, while negative clearance cross roller bearings have higher rigidity.

Sixth, the relative tilt of the inner ring and the outer ring

        Analyze the relative inclination of the inner and outer rings of the bearing (such as deflection of the shaft due to load, poor accuracy of the shaft and housing, or mounting tolerances), and choose to adapt to the conditions of use.
