eMG13

Features

  • For plain shafts
  • Single and dual seal
  • Elastomer bellows rotating
  • Unbalanced
  • Independent of direction of rotation

Advantages

  • 100 % compatible with MG13

  • Small outer diameter of bellows support (dbmin) enables direct retaining ring support, or smaller spacer rings
  • Optimal alignment characteristic through self-cleaning of disk/shaft
  • Improved centering across entire pressure operating range
  • No torsion on bellows
  • Shaft protection over entire seal length
  • Protection of seal face during installation due to special bellows design
  • Insensitive to shaft deflections due to large axial movement ability
  • Suitable for low-end sterile applications

Operating range

Shaft diameter:
d1 = 16 … 60 mm (0.63" ... 2,36")
Pressure: p1 = 18 bar (261 PSI),
vacuum ... 0.5 bar (7.25 PSI),
up to 1 bar (14.5 PSI) with seat locking
Temperature: t = -20 °C … +140 °C
(-4 °F … +284 °F)
Sliding velocity: vg = 10 m/s (33 ft/s)
Admissible axial movement: ±2.0 mm (±0.08")

Materials
