The DBH 9817 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its A 308 design and stepped height of 13 to 16 mm make it suitable for gearboxes, pumps and rotating equipment where axial space is limited. At MR Accesorios Industriales we carry it as part of our seals and oil seals line for maintenance and replacement.

This item is a DBH brand radial shaft seal, identified by the code 9817. According to the product page data, it runs on a shaft of 50 mm diameter and seats in a bore of 66.5 mm, with a height of 13.00/16.00 mm and an A 308 design. That double height indicates a profile with a mounting section and stepped lip, designed to cover the housing and keep the lip in even contact with the shaft.

Seals of this type are used in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment where oil or grease must be separated from the environment. They also appear in applications with splashing, dust or steam, where the lip must stop contamination without generating excessive friction. As a wear component, it is replaced at every teardown or at the first sign of leakage.

To install it, check that the shaft has no burrs or marks in the contact area and that the housing is clean and free of dents. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a tube or press that bears on the outer diameter, never on the lip. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.

If you need an equivalent or a different size, send us the code 9817, the shaft and housing dimensions and a photo of the old seal. With that we review the DBH line and compatible alternatives. We can also check the A 308 design against the manufacturer's data sheet to confirm that the height and profile match your application.

At MR Accesorios Industriales we carry the DBH brand within our seals and oil seals line. Send the code 9817 by WhatsApp and we will quote the seal with the dimensions shown on the product page. If you have questions about installation or want to compare with another size, write to us and we will look at it together.
