Rotary Seals
Split Rotary Shaft Seals
For sealing dynamic, rotary motion
Split Rotary Shaft Seals are made for easy installation. Shaft removal and dismantling of machinery are kept to a minimum, thus reducing downtime. This design is recommended for horizontal shafts in grease or below centerline in fluid–lubricated applications.
Seals can be supplied solid for original build and split for field replacement.
When installing a split seal, a retaining device is needed (i.e., cover plate) for proper axial compression to secure the seal in the housing; the split must be at 12 o’clock position. Both ends of the garter spring are twist connections.

These seals are also available in small quantities for repairs and seal replacements within 1-3 days.
