EagleBurgmann BT-C5.KU Shaft Seal

TYPE 59U/59B DIN Standard PTFE Wedge Seals"

TYPE 57B/58B/58U Elastomer O-Ring Seals"

 58U: John crane Type 58U replacement

The Type 57B and 58B are hydraulically balanced, multi-spring DIN 24960/EN 12756 seals. The Type 58U –is an unbalanced multispring DIN24960/EN12756 seal.They are versatile designs using components common to other o-ring and wedge type seals. They allow easy repair, reduce inventory, and permit a   simple conversion to unbalanced or wedge seals.
