The DBH 5233 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Because of its dimensions —75 mm shaft, 100 mm housing and 12 mm height— it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this brand and advises you on choosing the right seal for your application.

The DBH 5233 is an Lz design oil seal: a radial seal with a sealing lip and metal case, designed for shafts rotating inside a cylindrical housing. Its dimensions are 75 mm shaft diameter, 100 mm housing diameter and 12.00 mm height. The Lz design corresponds to a single-lip configuration with spring, suitable for retaining oil or grease under continuous rotation conditions. It is made of elastomer resistant to mineral oils and normal operating temperatures.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. In all these cases it serves two functions: preventing lubricant leaks to the outside and protecting bearings or bushings from the entry of contaminants. It is a wear part, so it should be checked at every preventive maintenance interval and replaced when leaks or abnormal noise appear in the seal area.

To install the 5233 oil seal, verify that the shaft has the specified dimension and a surface free of burrs or deep scratches; suitable roughness extends the life of the lip. Lubricate the lip before inserting it and use a tube or press that bears on the outer diameter, never on the elastomer. The housing must be clean and free of deformation. If the equipment operates with heavy vibration or high temperature, ask about compound or design variants that better withstand those conditions.

If you need an oil seal equivalent to the DBH 5233 or a nearby size, send us the full part number, the shaft, housing and height dimensions, and a photo of the old part if you have one. With that data we can look for an alternative within the same brand or from another brand we carry. We can also advise you if the mounting space allows a seal of a different height or if the lip design should be changed according to the type of lubricant.
