The DBH 1210 oil seal is a single-lip radial shaft seal that prevents oil or grease leaks and blocks dust and water from entering rotating shafts. With dimensions of 35 mm shaft, 52 mm housing and 12 mm height, it is press-fitted into gearboxes, covers and reduction boxes. It is a wear part: when the lip hardens or the spring loses tension, lubricant loss appears. MR Accesorios Industriales sells this brand and advises you on choosing the correct replacement.

This item is a DBH radial shaft seal, designation 1210, with the following dimensions: shaft diameter 35 mm, housing diameter 52 mm and height 12.00 mm. The Lx design indicates a single sealing lip with spring, intended for rotating shafts with internal lubrication. DBH is a brand MR sells, so the replacement keeps the original geometry and material. It is used to retain oil or grease inside an assembly and, at the same time, prevent contaminants from entering from the outside.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. It is also found on fan shafts, mixers and agricultural or process machinery. In all cases it works on a rotating shaft and inside a cylindrical housing, with the lip resting against the shaft surface. Its function is twofold: contain the lubricant and protect nearby bearings or bushings from the entry of particles.

To install it properly, check that the shaft has no burrs, deep scratches or wear in the contact area; a damaged shaft ruins the lip within a few hours. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking the lip. If the housing shows play or corrosion, correct it before installing. Selection involves respecting the shaft, housing and height dimensions, and choosing the lip material according to the temperature and the working fluid.

If you need an equivalent, send us the code 1210 along with the shaft, housing and height dimensions. It also helps if you tell us the type of fluid, the working temperature and the shaft speed. With that data we search the DBH line or another compatible alternative. If space allows, a seal with an additional lip or a different material can be evaluated, as long as the mounting dimensions stay within the housing tolerance.

Before replacing, check the condition of the shaft and housing: a new seal on a worn surface will not seal. If you have doubts about the lip orientation or the direction of rotation, ask us. At MR Accesorios Industriales we sell DBH seals and other sealing lines, and we help you identify the correct part. Send the code 1210 via WhatsApp and we will quote you.
