We offer a wide range of oil seals that comply with DIN 3760 and suit many different industrial needs and specific applications. From standard types such as A, AO and AS for general use, to B, BS and BO with an outer metal case for a precise fit, and C, CS and CO reinforced for aggressive environments. Types AP and ASP are designed for high liquid pressures and withstand up to 100 bar. We also offer special configurations such as Cassette (K7) oil seals, compact and robust against contaminants, and Combi (KOMBI) seals, which combine several sealing lips in a compact design for demanding environments such as agriculture. We also stock oil seals specifically for the automotive and motorcycle sectors, including PTFE-lipped types (PA) for high temperatures and speeds. All of them can be customised with the right elastomer and a stainless steel spring to optimise sealing efficiency and durability, ensuring reliable long-term performance.
You can consult the detailed datasheets for each of our types and subtypes, with all the technical information you need.
Our oil seals, manufactured to DIN 3760, cover a range of types designed to meet different industrial needs and specific applications. These include types A, AO and AS, the most standard designs, whose sealing lips suit general applications. Types B, BS and BO have an outer metal case, which makes them ideal where a precise fit in the housing is required. For more demanding conditions, types C, CS and CSO have a reinforced metal case, perfect for the most aggressive environments. Types AP and ASP are intended for applications where liquid pressure is higher than usual, and we can supply designs that withstand up to 100 bar.
Alongside these standard types, we offer special configurations tailored to different industries and applications. Cassette (K7) oil seals, for example, provide a compact, robust solution that rotates on itself and gives effective protection against contaminants. Combi (KOMBI) oil seals stand out for their ability to combine several sealing lips in a compact design, which makes them ideal for highly aggressive environments such as agriculture.
For automotive and motorcycle applications we supply oil seals designed to meet the sector’s rigorous standards, ensuring performance and reliability even under severe operating conditions. PTFE-lipped seals (PA) are particularly suited to high-temperature, high-speed environments, since they reduce friction and extend seal life.
At OSN, all our oil seals have one thing in common: they can be fully configured to the customer’s requirements. We use different elastomers to match the specific temperature, pressure and operating media. The models can also be fitted with stainless steel springs to improve the efficiency and longevity of the sealing system, ensuring reliable operation over time.
