The DBH 9657 oil seal is a radial shaft seal with A 201 design, intended to retain lubricant and block the entry of contaminants in rotating equipment. It is mounted on shafts that rotate inside a housing and works with its elastomeric lip bearing against the running surface. It is a wear part: when the lip hardens or becomes damaged, oil loss appears and it should be replaced. MR Accesorios Industriales carries this brand and advises you on choosing the correct oil seal.

This item is a DBH radial shaft seal identified by code 9657 and design A 201. The A 201 design corresponds to a single-lip seal with spring, for general use on rotating shafts. The designation 9657 is the number the manufacturer assigns to this size and configuration; it is not a universal size code.

Radial shaft seals of this type are used in gearboxes, pumps, electric motors, rollers and power transmission equipment. Their function is twofold: to retain the oil or grease inside the assembly and to prevent dust, water or particles from entering. In environments with vibration or varying temperature, the lip must maintain contact without overheating. That is why selecting the lip and spring material is as important as the size.

To install an oil seal, work with a clean, burr-free shaft, lubricate the lip before sliding it on and use a support tube so as not to damage it. The position of the lip relative to the direction of rotation and the concentricity of the housing determine its service life. If the shaft is worn, a repair sleeve can solve the problem. At MR Accesorios Industriales we help you review these points before quoting.

If you need an equivalent, send us code 9657 along with the shaft and housing dimensions, a photo of the part and the type of fluid it seals. With that data we look for alternatives in the same series or in compatible designs. We can also offer you the oil seal in another lip material if the environment requires it.
