ABSTRACT:
An improved alignment device and/or sealing device for creating an alignment of seals in split pillow block. An alignment device having a cylindrical member surrounding a shaft includes a plurality of sacrificial bearings fitted to the inside diameter of the carrier or alignment device and fixing the radial and angular position of the carrier and anything which is permanently attached to the carrier. This radial location of the carrier and/or elements attached thereto permits the seal, carrier, and housing to be self-aligned in conformance with the bearing, shaft, and housing. The axial positioning of the carrier and/or anything permanently attached thereto, with respect to the shaft, is accomplished by projections and resilient elements fitted between the housing and the alignment device of this invention. This invention permits the self-aligning of the bearing, the shaft, the seal, and alignment device to the housing. In the prior art, the shaft, along with the bearing automatically misaligned to the seal and the housing, there being no carrier and/or alignment device similar to this invention.
