The DBH 5133 oil seal is a single-lip radial seal with spring, designed for 20 mm rotating shafts and 30 mm housings. Its 7 mm height and Lz design make it suitable for retaining lubricant and blocking contaminants in gearboxes, pumps and electric motors. MR Accesorios Industriales carries this brand and advises you so that you choose the correct seal for your application.

This item is a DBH radial shaft seal, identified with the designation 5133. Its dimensions are shaft (d) 20 mm, housing (D) 30 mm and height (h) 7.00 mm. The Lz design corresponds to a sealing lip with spring, intended for rotating shafts. The DBH brand is a brand that MR carries, so you can ask us about this reference or about equivalent alternatives.

Radial shaft seals such as the DBH 5133 are used in equipment where there is a shaft rotating inside a housing and oil or grease leaks must be prevented, while at the same time preventing the entry of dust or water. Typical applications: gearboxes, centrifugal pumps, electric motors, reducers, mixers and machine tools. Also in rollers and transmission shafts operating in dirty environments.

To install this seal, check that the shaft has the 20 mm dimension and the housing 30 mm, with a housing width that accepts the 7.00 mm height. The shaft surface must be ground and free of burrs; lubricate the lip before inserting it. If the equipment runs at high speed or with a lot of pressure, ask us about variants with reinforcement or alternative material. Selection depends on speed, temperature and type of lubricant.

If you need a seal with nearby dimensions — for example, a 19.05 mm shaft or a 32 mm housing — or if code 5133 is not available, we can look for an equivalent in other brands we carry. For that, send us the shaft diameter, the housing diameter and the height, or directly the original code. We can also quote the same seal in another material if your application requires it.
