Features
- The drive band's "dent and groove" design eliminates overstressing of the elastomer bellows to prevent bellows slip and protect the shaft and sleeve from wear.
- Non-clogging, single-coil spring provides greater dependability than multiple spring designs and will not foul due to fluid contact.
- Flexible elastomer bellows automatically compensates for abnormal shaft-end play, run-out, primary ring wear and equipment tolerances.
