Claim:
1. A seal-bearing assembly for a mechanical device having a shaft with reciprocating and/or rotational movement, comprising: a first substantially rigid high performance polymeric cylindrical outer bearing; a second substantially rigid high performance polymeric cylindrical outer bearing spaced apart from and axially aligned with the first outer bearing; and at least two cylindrical textile packing members, each cylindrical textile packing member including carbon yarn and each being positioned adjacent to one of the first and second outer bearings, wherein the first and second outer bearings are closely dimensioned to fit into the seal cavity of a device with an inner bore closely dimensioned to fit over the shaft and within the inner bore of the cavity of the device to provide a bearing surface for the shaft, and wherein the cylindrical textile packing members each have an inner radius and an outer radius that are approximately equal to the inner and outer radii of the bearings to fill the seal cavity of a mechanical device.
