Quick Answer: A radial shaft seal is a rotary oil seal that fits into a housing bore and seals against a rotating shaft. Buyers searching for a radial shaft seal manufacturer should compare shaft diameter, housing bore, width, material, temperature, pressure, speed, and fluid. CORASEALS supplies radial shaft seals in standard and custom profiles and quotes from drawings, samples, or complete application data.
An inquiry for a radial shaft seal manufacturer usually involves a rotating shaft, a housing bore, and a fluid that must be retained. The buyer needs a supplier that can confirm dimensions, material, lip design, and production source. CORASEALS handles that supply process and consolidates the quote across standard and custom profiles.
CORASEALS is an industrial seal supplier and exporter. CORASEALS supplies radial shaft seals from production-qualified supply chains. This gives buyers one quote path for standard sizes, custom dimensions, and different material grades. A radial shaft seal is not quoted by size code alone. CORASEALS asks for the full operating data to reduce the chance of a near-fit seal reaching the application.
Radial shaft seal dimensions are normally written in the order ID × OD × width. Confirm whether the ID is the shaft diameter or the seal inside diameter. The OD must match the housing bore. The width must match the cavity or counterbore depth. A size alone does not define the lip type, spring arrangement, case material, or compound.
Standard radial shaft seals are commonly referenced to DIN 3760 or ISO 6194. These references help identify shaft and bore combinations. A standard number alone does not confirm lip design, spring type, dust lip, or material. Always pair the standard with a section drawing.
Codes such as TC, SC, TB, VB, and DC appear in many oil seal catalogs, but their definitions are not universal. A TC code from one source may have a different dust lip or spring arrangement from another source. Before ordering, compare the cross section drawing and confirm the lip, spring type, dust lip, and case material.
Material choice cannot be based on price alone. A low cost compound that hardens or swells in service will cause early leakage and shaft wear. Send the actual fluid and temperature data before finalizing the compound.
Shaft speed is not only rpm. Surface speed depends on shaft diameter and rpm. A seal may work at a given rpm on a small shaft and fail at the same rpm on a large shaft. Standard radial shaft seals are usually low pressure components. If the cavity is pressurized, state the pressure. A lip seal can deform under pressure and may require a special profile or backup ring.
Radial shaft seals are used in gearboxes, pumps, electric motors, axle assemblies, wheel hubs, agricultural machinery, construction equipment, and industrial drives. A gearbox oil leak and a water pump shaft application require different compounds and lip designs. State the application and fluid condition in the inquiry.
Send us the seal type, material, ID × OD × width, operating temperature, pressure, medium, shaft speed, drawing, sample photo, and required quantity. If only the shaft diameter and housing bore are known, state that clearly. CORASEALS will confirm the profile and compound before quoting.
Q: What is the difference between a radial shaft seal, a rotary shaft seal, and an oil seal?
In most industrial purchasing, these three terms describe the same product family of rotating shaft lip seals. The term radial shaft seal is common in metric and ISO-related contexts.
Q: What information should I send to get a radial shaft seal quote?
Send the seal type, material, ID × OD × width, operating temperature, pressure, medium, shaft speed, drawing, sample photo, and required quantity. If you have a sample or drawing, include that first.
Q: Which material should I choose for a radial shaft seal?
NBR is common for mineral oil. FKM suits higher temperature and more aggressive fluid exposure. HNBR suits higher heat and abrasion in selected oil systems. EPDM suits water and steam but not most mineral oil. Send the fluid and temperature data for a confirmed compound.
Q: Can CORASEALS supply non-standard radial shaft seal sizes?
Yes. Custom radial shaft seals can be quoted from drawings or samples. Provide shaft diameter, housing bore, bore depth, and material requirements. Do not order a custom size by type code alone.
Q: How do I confirm a TC type radial shaft seal before ordering?
Send the type code and the section drawing. Different catalogs define TC and similar codes differently. CORASEALS compares the lip, spring, dust lip, and case material before confirming interchange.
Send us the seal type, material, ID × OD × width, operating temperature, pressure, medium, shaft speed, drawing, sample photo, and required quantity.
