Rotary Shaft Seals

Spring-Loaded Rotary Shaft Seals

Spring-Loaded Rotary Shaft Seals

Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.

Also known as grease seals, these are designed to retain thick lubricant at low pressure. They have a light grip on the shaft that creates less friction than spring-loaded seals.

Split Rotary Shaft Seals

Split Rotary Shaft Seals

Swap out old seals without disassembling components—these seals come split for easy installation. They're also known as clipper seals.

Mechanical Pump Shaft
