The difference between a steel protect and rubber sealing should do with greatest rpm. Specified the 10.8k rpm max alternator pace when Utilized in the kind 4 motor with 5400rpm rev limiter, double rubber seals will suffice but it surely's crucial the bearings be sealed since the inside the alternator gets extremely dusty, Particularly in between the slip ring and its bearing.
