: An exposed metal outer case, offering a tighter press-fit for applications where high axial ejection forces might occur.

The DIN 3760 standard specifies dimensions and technical requirements for rotary shaft lip seals used to retain fluids or grease in unpressurized equipment, or equipment operating under low differential pressures (typically up to 0.05 MPa or 0.5 bar). Core Seal Anatomy

While there are several variations, the two most frequent types defined in the standard are:

Used primarily to retain lubricants. The elastomer outer diameter (OD) provides excellent sealing capabilities inside the housing bore, even if the housing expands thermally or has minor surface roughness. Type AS (Single Lip with Dust Lip)

A seal with an exposed metal outer surface. These are used for more permanent, rigid seating in the housing.

Common standard size combinations listed in the official documentation include: 15mm x 24mm x 7mm 20mm x 30mm x 7mm 25mm x 35mm x 7mm 30mm x 42mm x 7mm 40mm x 52mm x 7mm 50mm x 65mm x 8mm Troubleshooting Premature Seal Failure

Material selection directly affects the seal’s temperature range, chemical resistance, and lifespan. The standard references several common elastomers: Elastomer Material Abbreviation Temperature Range Best Used For -30°C to +100°C General engineering, mineral oils, grease Fluorocarbon Rubber FKM / Viton -20°C to +200°C High temperatures, chemicals, synthetic oils Polyacrylate Rubber -25°C to +150°C Transmission fluids, automotive engine oils Silicone Rubber -55°C to +150°C Extreme thermal ranges, low friction needs Standard Dimensions and Nomenclature

The effectiveness of a DIN 3760 seal depends heavily on the elastomer chosen for the application.

Emma had worked with seals before, but she wanted to make sure she was choosing the right one for this particular application. She had heard of a German standard for seals, DIN 3760, and she suspected it might be relevant to her design. The elastomer outer diameter (OD) provides excellent sealing

The shaft surface must have a minimum hardness of 45 HRC. For high peripheral speeds or abrasive environments, a hardness of 55 HRC to 60 HRC is recommended.

Standard DIN 3760 seals can withstand a maximum pressure of 0.5 bar (

The DIN 3760 standard specifies the design, dimensions, and testing requirements for radial shaft seals used in rotating machinery. The standard covers seals with a elastomeric seal ring and a metal casing.
