Did some searching.  May have found a match in the Timken catalog.  471551.   Construction and measurements appear to be compatible...........except it is a bit wider than the OEM seal (.252" vs .190").  Don't know if that's a deal breaker or not.  Did not find a Metric match.  From the Timken catalog:

Timken 471551

Style:       470 (double lip w spring) 

Material:   S (Nitrile rubber) 

Shaft dia:  0.563"

Bore dia:   1.378"

Seal OD:    1.384"

Seal width:0.252"



Put that Timken # into the handy-dandy CR/SKF seal interchange thingee...............and found an SKF match.  SKF 5756.
