About the 63 series
Same bore as the 62, but a bigger OD and wider. Heavier load, same shaft. You'll find them in pumps, compressors and the drive end of bigger motors.
If a 62 keeps failing and the housing has room, a 63 is the usual upgrade. Check the housing bore first; it won't fit a 62's seat.
Same bore, different size
