What are the ? What fluid or lubricant is being contained?
This comprehensive guide breaks down everything contained within the DIN 3760 standard, helping you apply its specifications accurately to your engineering projects. What is the DIN 3760 Standard?
The operational limits of a DIN 3760 oil seal depend heavily on the elastomer compound used for the sealing lip. Selecting the correct material requires balancing fluid compatibility, temperature ranges, and peripheral shaft speeds. Elastomer Compound Common Abbreviation Temperature Range Maximum Surface Speed Best Suited For -40°C to +100°C Up to 12 m/s
Radial lip seals are critical components in many industrial applications, as they prevent fluid leakage and contamination, ensuring the reliability and longevity of equipment. The DIN 3760 standard ensures that these seals meet specific requirements for performance, safety, and quality, providing a benchmark for manufacturers and users alike.
| Feature | | Type B | Type C | | :--- | :--- | :--- | :--- | | Outer Diameter (OD) | Rubber-covered (Fully coated in elastomer) | Bare metal case (Steel) | Metal case with an additional reinforcing cap | | Primary Function | General-purpose sealing | High extraction force resistance | High rigidity for rough conditions | | Key Advantage | Excellent static sealing in the housing bore, tolerates slight bore imperfections | Higher mechanical strength; resistant to twisting during installation | Superior stability for very large diameters and high-pressure assembly errors | | Dust Lip Option | Type AS (A + Staublippe/dust lip) | Type BS (B + dust lip) | Type CS (C + dust lip) | din 3760 pdf
In industrial machinery, keeping lubricants inside a system while preventing contaminants from entering is a critical challenge. The standard defines the dimensions, materials, and technical requirements for radial shaft seals—often referred to as oil seals or rotary shaft lip seals—used to achieve this.
The flexible elastomeric part that maintains contact with the rotating shaft, creating a fluid-tight barrier.
: A metal outer case with a reinforcing cap, designed for the most demanding or "rough" installation environments. Precision in the Details
The standard specifically applies to rotary shaft lip seals used for retaining grease or fluid in unpressurized equipment, or equipment with a low differential pressure, that has rotating shafts. It defines the dimensions, designations, materials, surface protection, marking, and detailed installation requirements for these critical components. What are the
Propose your parameters, and I can calculate the exact for your design.
The shaft entry must be chamfered and polished to prevent the sealing lip from turning inside out or cutting during installation.
What are the and shaft speeds (RPM) ?
Same as Type B, but features an additional dust lip for external contaminant exclusion. Type C: Reinforced Metal Outer Diameter What is the DIN 3760 Standard
When installing seals with a metal outer casing (like the AS260x230x23mv), use a mechanical or hydraulic press that applies even pressure exclusively on the outer metal ring.
: Often used in large machinery or heavy-duty applications, Type C adds an extra metal reinforcing cap to the standard Type B design for maximum rigidity.
Excellent for extremely low temperatures and specific high-temperature applications, though it may have lower wear resistance than NBR in abrasive environments. Operational Limits and Tolerances
