The DBH 8333 oil seal is a single-lip radial shaft seal that is fitted into the housing and seals against the rotating shaft. Its function is to retain the lubricant inside the assembly and stop dust, water or particles that wear bearings and bushings from entering. Thanks to its size of 46 mm shaft, 65.50 mm housing and 7 mm height, it is used in gearboxes, pumps and power transmission equipment where axial space is limited.

This item is a DBH radial shaft seal with designation 8333. According to the product page data, it works on a shaft of 46 mm diameter, fits into a bore of 65.50 mm and has a height of 7.00 mm. The indicated design is Lx, which corresponds to a single sealing lip with spring. The DBH brand is an official brand that MR carries, so the product arrives with its identification and origin traceability.

Seals of this size are found in equipment where a shaft rotates inside a housing with lubricant: gearboxes, centrifugal pumps, mixers, screw conveyors and machine tools. They also appear in electric motors and speed reducers, where they serve the dual function of containing the oil or grease and preventing dirt from the environment from entering. If the seal fails, lubricant loss accelerates wear on bearings and gears.

To install a radial shaft seal, check the condition of the shaft: it must have no burrs, deep scratches or wear in the lip contact area. The surface where the lip seats is lubricated with the same grease or oil as the equipment before inserting the seal, and the installation tool must rest on the outer edge, never on the lip. If the housing has a shoulder or a radius, check that the seal seats fully and that the 7.00 mm height is compatible with the cover or the retainer.

If you need a nearby size, a different design or a seal for another shaft and housing combination, the most practical thing is to send the code 8333 or the full size (46 x 65.50 x 7 mm) via WhatsApp. With that data we can look for the equivalent in the same brand or in another line, always confirming tolerances and lip type against the manufacturer's product page. We can also advise you if the seal is mounted on a worn shaft and a repair sleeve should be considered.

At MR Accesorios Industriales we work with seals and oil seals for maintenance and replacement. If you have the code engraved on the old seal, a photo or the size measured with a caliper, send it via WhatsApp and we will help you identify the part. That way you avoid buying a seal that does not match and reduce equipment downtime.
