  • Transport jig and transport method for double-row self-aligning roller bearing
    Patent number: 11111963
    Abstract: Provided is a transport jig to be packed together with a double-row self-aligning roller bearing having an intermediate flange when the double-row self-aligning roller bearing is transported. The transport jig is formed in a ring shape having inner and outer diameters that allow the transport jig to be radially accommodated between an outer circumferential surface of an end portion of an inner ring and an inner circumferential surface of an end portion of an outer ring of the double-row self-aligning roller bearing, has a shape such that one side surface of the transport jig comes into contact with an end surface of each rolling element of the double-row self-aligning roller bearing and another side surface of the transport jig protrudes beyond end surfaces of the inner and outer rings, and is formed from a material softer than the rolling elements.
