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.
