Automotive transmissions and differentials using high-additive oils. Operating Limits: Pressure and Speed

This guide provides a detailed overview of the DIN 3760 standard, its types, material selection, installation guidelines, and how to find technical documentation (PDFs). 1. What is DIN 3760?

Possessing the is only half the battle. Correct installation is critical. Here is what the standard implies for good engineering practice:

Extreme thermal applications with low physical stress. Poor dry-running properties. Polyacrylate Rubber -25∘Cnegative 25 raised to the composed with power C +130∘Cpositive 130 raised to the composed with power C din 3760 pdf

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

Automotive applications, engine oils, and transmission fluids with extreme-pressure (EP) additives. Critical Installation and Housing Tolerances

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

: Manufacturers like Tameson and Elastotechnic provide free dimension tables and material data sheets based on the standard.

When searching for a , engineers, designers, and procurement specialists are typically looking for precise dimensions, material specifications, and installation tolerances. Here is what the standard implies for good

Some manufacturers add "R" for right-hand rotation or "L" for left-hand rotation if the seal has a hydrodynamic helix (a spiral pumping aid). Standard DIN 3760 does not require this, but it is a common supplement.

Includes an additional inner metal shell. This design offers superior structural rigidity for harsh environments or large dimensions.

Same as Type A, but includes an additional protective lip (dust lip) facing outward.

: The seal is reinforced by a metal stiffening plate (steel) and utilizes a garter spring (spring steel) to maintain constant radial load on the sealing lip against the shaft.
