Custom Metal-Cased Shaft Seal Types

Standard - Single, spring-loaded lip. This is the most common design used when primary function is either exclusion or retention.
D1 - Two sealing members with opposed lips. Used when positive sealing is required from two directions or when necessary to seal/separate fluids.
D2 - Dual elements used in a single purpose, severe duty environment as an excluder or for fluid/lubricant retention.
D3 - Spring-loaded primary sealing lip with a springless secondary dust lip at the back of the seal. The dust lip prevents dirt, etc. from damaging the main element.
D4 - A further variation of dual sealing. Here the spring loaded element is preceded by a dust lip.
D5 - From time to time arduous conditions require a special dual seal which will allow grease to be administered to the center cavity after the seal is installed, thereby cleaning the wiping lips of extraneous matter.
D6 - Two seals fitted back to back, one with indentations, which again allows the easy passage of lubricant administered through a grease nipple.
G1 - Where both axial and radial dimensions are restricted we offer a springless seal.
G2 - Limited space requiring dual sealing poses a problem which is overcome by our G2 type.
G3 - A triple lipped springless seal is ideal for grease and thick oils.
SAFEGARD - Sealing lip is energized without the use of metal springs. Used when space is limited and use of a loose garter spring could result in component damage.
