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

This item is a DBH radial shaft seal identified with the code 9657 and design A 201. The design A 201 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. To confirm shaft, housing and width dimensions, the code must be cross-referenced against the manufacturer's technical data sheet, because those numerical values are not published in this record.

Radial shaft seals of this type are used in gearboxes, pumps, electric motors, rollers and 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 variable temperature, the lip must maintain contact without overheating. That is why the selection of the lip material and the spring is as important as the size.

To install a seal, work with a clean shaft free of burrs, lubricate the lip before sliding it on and use a support tube to avoid damaging it. The position of the lip relative to the direction of rotation and the concentricity of the housing determine the 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 or a nearby size, send us the 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 seal in another lip material if the environment requires it.
