The DBH 6404 oil seal is an Ls-design radial seal placed between a rotating shaft and its housing to retain lubricant and block the ingress of contaminants. Its dimensions of 48.30 mm shaft diameter, 85.85 mm housing diameter and 8.00 mm height make it suitable for equipment where axial space is limited and a reliable barrier against dust, water or particles is required.

This item is a DBH 6404 radial shaft seal, identified by its designation 6404. Its dimensions are: shaft diameter (d) 48.30 mm, housing diameter (D) 85.85 mm and height (h) 8.00 mm. The Ls design corresponds to a single sealing lip with spring, intended for rotating shafts. The DBH brand is an official brand that MR carries, so the replacement part maintains the original geometry and compound for a direct fit in the housing.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, spindles and transmission equipment where oil or grease leaks must be prevented and bearings protected from the ingress of dirt. Due to its 8.00 mm height, it is common in assemblies where the seal sits in a machined cavity with little available space and effective sealing is required at moderate speeds.

To install it correctly, check that the shaft diameter is within the recommended tolerance and that the contact surface is polished and free of burrs. The housing must have the correct diameter and depth for the 85.85 x 8.00 mm seal. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and use an installation tube to avoid damaging the spring. If the shaft shows wear, consider a repair sleeve or an alternative size.

If you need an equivalent seal or a nearby size, the most practical approach is to send us the code 6404 or the current dimensions of your shaft and housing. With that data we can look for a compatible alternative within the DBH line or other brands we carry. We can also advise you if the Ls design is not the most suitable for your application and another lip type or material should be considered.
