Super Precision Angular Contact Ball Bearing Excavator Usage

  Angular contact ball bearing excavator usage are mechanical components.Which used in the walking and rotating mechanisms of excavators. Its installation involves the assembly of walking motor bearings and walking drive bearings.And requires the use of hydraulic excavator bearing seat installation auxiliary devices to achieve precise positioning. The installation and disassembly methods should be determined based on the structure, size.And compatibility with the bearing components of the excavator. The pressure for installation and disassembly should be directly applied to the end face of the tight fitting excavator bearing retaining ring.And cannot be transmitted through the rolling elements of the excavator bearing.As this will cause pressure marks on the working surface of the excavator bearing.Affecting its normal operation and even causing damage. The retaining frame, sealing ring, dust cover and other parts of excavator bearings are easily deformed.And the pressure of installing or disassembling excavator bearings cannot be applied to these parts.

Angular contact ball bearing excavator usage can withstand large radial loads.Mainly combined radial and axial loads.As well as torque loads.Limiting the axial displacement of both sides of the shaft. The tilting ability between the inner and outer rings.Which are mainly used to limit the bidirectional axial displacement of the shaft and housing, is limited. The allowable tilting angle depends on the internal clearance, bearing size, internal design.And the forces and moments acting on the bearing. The maximum allowable tilting angle should ensure that no excessive additional stress is generated inside the bearing. If there is a tilt angle between the inner and outer rings.It will affect the service life of the bearing.And cause a decrease in the operating accuracy of the bearing.And an increase in operating noise. Double row angular contact ball bearings generally use nylon retainers or brass solid retainers. When installing double row angular contact ball bearings.It should be noted that although the bearing can withstand bidirectional axial loads.If there is a gap for installing the ball on one side.Care should be taken not to let the main axial load pass through the groove edge on the side with the gap. When using bearings, attention should be paid to ensuring that the raceway on the side without the ball mounting notch bears the main load.
