The Model 758 Size 58 Encoder is a heavy duty, extremely rugged, reliable, yet compact European standard 58mm diameter encoder, designed for harsh factory and plant floor environments.  Shaft loading is no problem for the double-shielded ball bearings; their 36Kg load rating ensures a long operating life.  With the optional heavy-duty shaft seal, the Model 758 is rated IP65.  Two European standard mounting options are available:  Clamping Flange (420 Type) or Synchro Flange (426 Type).  The Model 758 is the perfect replacement encoder for units requiring the European mount.
