Nachi excavator bearings BA290-3A Angular Contact ball bearing BA290-3A excavator ball bearing size chart

This kind of bearings are mianly used for excavator machinery.It is thin ring angular contact ball bearing. This kind of angular contact ball bearing has big contact angle(40 degree),so can under take big axial load ,and aslo axial radial allied load .Moreover it can carry heavier load capacity than the same size bearings because it has more balls inside .It is widely used for all imported exavator.

Excavator bearing installation:

Excavator bearing installation and removal methods, should be according to the excavator bearing structure, size and excavator bearing parts with the nature.Installation, disassembly pressure should be directly added to the end face of tight fit excavator bearing stalls circle, not by the excavator bearing rolling elements to transmit pressure, because this will be caused by the excavator bearing work surface indentation, impact excavator bearing normal workeven make excavator bearing damage. Excavator bearing cage, seals, dust cover parts easily deformed, installation or demolition excavator bearing pressure can not be added to these parts.
