A standard smooth outer diameter version for basic fluid retention.
Engineers, maintenance professionals, and procurement specialists frequently search for a "DIN 3760 PDF" to verify dimensions, tolerances, and material requirements. This comprehensive guide covers everything outlined in the standard document to help you select, design, and maintain these vital seals. What is the DIN 3760 Standard?
The housing bore should be machined to an H8 tolerance.
Identical to Type A but includes an additional, non-spring-loaded auxiliary lip (dust lip). din 3760 pdf
Understanding this standard is vital for engineers, maintenance professionals, and procurement specialists. This article provides an in-depth breakdown of DIN 3760, its design variations, material options, and tips for locating official technical documentation. 1. What is the DIN 3760 Standard?
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).

An outer elastomer-covered metal insert. This is the most common type, providing excellent sealing at the housing even with thermal expansion.
Similar to Type B, this variant features a bare metal outer sleeve combined with an additional trailing dust lip for enhanced protection against environmental contaminants. Type C (Form C)
Standard seals are typically manufactured from two primary elastomer types depending on temperature and chemical resistance: Tameson.com NBR (Nitrile Rubber) What is the DIN 3760 Standard
An added to any variant (such as Form AS) indicates the inclusion of an auxiliary dust lip . This secondary lip functions without a garter spring and acts as a mechanical barrier against external dirt, dust, and moisture splash. When using dust lips, filling the internal cavity between the primary and secondary lips with grease minimizes friction during operation. Core Technical Specifications & Operating Limits
The standard defines the dimensions and requirements for rotary shaft lip seals (oil seals) used to retain fluids or grease in unpressurized or low-pressure equipment. You can view or download detailed technical PDFs from the following sources:
