Known for its high-performance capabilities. It handles extreme temperatures (up to +200 °C) and aggressive media, making it ideal for heavy machinery, chemical processing, and high-temperature gearboxes.

Never install a seal dry. Always apply a thin layer of grease or oil to the lip and the shaft before assembly. Why Engineers Use the DIN 3760 PDF

For speeds above 4 m/s or contaminated media, it should be at least Shaft Surface Finish: Roughness must be within cap R sub a 0.2 to 0.8 cap R sub z Shaft Tolerance: Recommended ISO tolerance is Housing Bore: Recommended tolerance is , with a surface roughness of cap R sub a 1.6 to 6.3 norelem USA Rotary shaft lip seals DIN 3760 | norelem din 3760 pdf

: A rubber-covered outer diameter, providing excellent static sealing even in housings with high thermal expansion or surface roughness.

The standard also specifies the metallic casing material (typically non-corrosive steel like DC01 or DX51D) and the garter spring material (usually stainless steel or carbon steel).

The standard primarily addresses seals made of elastomers such as: Known for its high-performance capabilities

The standard was originally established by the German Institute for Standardization (Deutsches Institut für Normung) and remains active, with the current 1996 edition often used in parallel with the international standard. Core Specifications of DIN 3760

Under DIN 3760, seals are typically categorized by their construction: Type A (Single Lip): A basic seal designed to retain lubricants. Type AS (Single Lip with Dust Lip):

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 Always apply a thin layer of grease or

Often caused by sharp edges on the shaft keyway scoring the delicate sealing lip during assembly. Always use an installation sleeve over keyways.

The shaft finish must be tightly controlled. The standard recommends a roughness of
