The DBH 8433 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent the entry of contaminants in rotating equipment. With dimensions of 25 mm shaft, 40 mm housing and 16 mm height, and a design A 053, it is mounted in gearboxes, pumps, motors and transmissions. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified with the code 8433. Its dimensions are 25.00 mm shaft diameter, 40.00 mm housing diameter and 16.00 mm height. Design A 053 corresponds to a specific construction configuration from the manufacturer. The sealing lip works against the rotating shaft, while the outer diameter fits into the housing cavity to fix the position and seal statically.

Radial shaft seals such as the DBH 8433 are used in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. Their function is to retain the oil or grease inside the assembly and block dust, water or particles that could damage the bearings and gears. They are critical components in industrial maintenance because a sealing failure leads to loss of lubricant and premature wear.

To install this seal, check that the shaft has the indicated size and a surface free of scratches and burrs; a suitable roughness favors the life of the lip. Lubricate the lip before inserting it and use an installation tube that rests on the outer diameter, never on the lip. The 16 mm height must match the depth of the housing. If the equipment runs at high speed or with a lot of dirt, ask about variants with an auxiliary lip or an alternative material.

If you need a seal equivalent to the DBH 8433, the most practical thing is for you to send us the full code, the shaft, housing and height dimensions, and a photo or sample of the old seal. With that data we can look for a compatible alternative within the brands we carry. We can also advise you if a replacement with a different lip or case geometry needs to be evaluated.
