Type 1/1A/1B/2/2B

These are multi-purpose nonpusher elastomer bellows seals for industrial applications. Designs are available in single, double and balanced arrangements. The bellows technology is available as a cartridge in Type 5611 seal range. Incorporating a spring adapter creates a low profile, enabling it to fit small cross section stuffing boxes. Mechanical drive prevents shaft damage and eliminates overstressing of bellows. The seal head is self-aligning, automatically adjusting for abnormal shaft endplay run-out, primary ring wear and equipment tolerances. Non-clogging single-coil spring is not affected by build-up of solids.
