- Self-adjusting elastomer bellows compensate for abnormal shaft end play and primary face sealing wear
- Effects of radial and axial shaft end play are minimized by uniform spring pressure
- Positive drive is transmitted through the drive band and drive notches, which absorb breakout and running torque
- Damaging stresses on the elastomer bellows are prevented
- Slippage is eliminated, thus protecting shaft and sleeve against wear and scoring
- The result is long seal life
- The seal's large single coil spring is much sturdier than a multiple spring construction design
- The spring is non-clogging, self-cleaning and will not foul up due to fluid contact
- Corrosion and clogging problems are eliminated
