Rotary Shaft Seal / Oil Seal
Rotary shaft sealsalso known as Oil seals, used in various industrial applications like automotive, refrigerator, HVAC, etc. These shaft seals are designed to prevent the leakage of lubricants and combustion gases, dirt and other harmful agents from entering a system’s components. They are made from a combination of rubber and metal, but other materials such as thermoplastics, elastomers and graphite can also be used.
Type A Single Lip – Rubber Coated with Spring (Rotary shaft Seals or Oil Seals)
DIN: 3760 Standard.
Common Materials: Nitrile, Fluorocarbon, Silicone, EPDM, Polyacrylate, Neoprene.
Spring make: Carbon Steel Stainless Available.
Pressure Rating: Max 7psi.
Mounting: Press-fit.
Comments: Best suited for rotary motion. They are used for sealing grease and generally for sealing lower pressure (up to 0.5 bar/7psi) fluids, heavy oils, and lubricants, depending on shaft speed. The backup ring supports sealing under medium pressure (4 bar/57psi).
Type ADL Double Lip – Rubber Coated w/ Spring (Rotary Shaft Seals or Oil Seals)
Comments: Similar to Type A seals. Additional (Double) Lip helps seal medium dirt from foreign materials.
Type AW – Rubber Coated – No Spring (Rotary Shaft Seals or Oil Seals)
Comments: Like type A seals. Best suitable for slow speed, used for non-pressure medium mainly for grease or viscous fluids. Less critical sealing applications.
Type B Single Lip – Metal Case with Spring (Rotary Shaft Seals or Oil Seals)
Comments: The construction is suitable for housing with keyways. Best suited for rotary motion. They are used for sealing grease and generally for sealing lower pressure (up to 0.5 bar/7psi) fluids, heavy oils, and lubricants, depending on shaft speed.The backup ring supports sealing under medium pressure (10 bar/140psi).
Type BDL Double Lip – Metal Case w/ Spring (Rotary Shaft Seals or Oil Seals)
Comments:Like Type B seals. Additional (Double) Lip helps seal medium dirt from foreign materials.
Type BW Single Lip – Metal Case – No Spring (Rotary Shaft Seals or Oil Seals)
Comments: Like type B seals. Best suitable for slow speed, used for non-pressure medium mainly for grease or viscous fluids—less critical sealing applications.
Type C Single Lip – Full Metal Case with Spring (Rotary Shaft Seals or Oil Seals)
Comments: The construction is meant for robust & muddy applications. The oil seal requires additional protection from the cover. Best suited for rotary motion. They are used for sealing grease and generally for sealing lower pressure (up to 0.5 bar/7psi) fluids, heavy oils, and lubricants, depending on shaft speed. The backup ring supports sealing under medium pressure (10 bar/140psi).
Type CDL Double Lip – Full Metal Case w/ Spring (Rotary Seals or Oil Seals)
Comments: Like Type C seals. Additional (Double) Lip helps seal medium dirt from foreign materials.Like Type C seals. Additional (Double) Lip helps seal medium dirt from foreign materials.
