Split Rotary Shaft Seals


Side 1	Side 2	Profile

Replace old seals without disassembling components—these seals come split for easy installation. Also known as clipper seals, they retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip to prevent leaks; fasten the hook and eye closure to secure. Press-fit seals into the housing bore; they fit tight for installation without a cover plate.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Spring-Loaded Rotary Shaft Seals for Misaligned Shafts


Side 1	Side 2	Profile

Designed with an extended lip, these seals have the flexibility to accommodate shaft misalignment up to 0.125". Also known as clipper seals, they retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip to prevent leaks. Press-fit seals into the housing bore around the shaft; they fit tight for installation without a cover plate.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
