At MR Accesorios Industriales we sell it as a brand and advise you so you choose the right seal for your equipment.

This item is a radial shaft seal from the DBH line, identified with the code 5253. Its dimensions are: shaft diameter 20 mm, housing diameter 35 mm and height 10.00/13.00 mm. The A 135 design corresponds to a seal with a sealing lip and metal body, suitable for applications requiring a barrier against oil or grease. The designation 5253 is the reference you will find on the manufacturer's product page for this size.

Radial shaft seals such as the DBH 5253 are used in equipment with rotating shafts: gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. Their function is twofold: to prevent lubricant leaks to the outside and to block the entry of dust, water or particles that accelerate wear on bearings and gears. In the food, chemical or process industries, choosing the right material and design is key to durability.

To install a radial shaft seal, check that the shaft has no burrs or marks and that the sealing surface is polished. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The housing must be clean and free of deformation. If the seal replaces a worn one, also check the condition of the shaft: a scratched or worn track means the lip will not seal properly, even if the seal is new. The 10/13 mm height means it can be fitted in cavities of different depths within that range.

If you need a seal equivalent to the DBH 5253, the most practical thing is to send us the full code, the shaft, housing and height dimensions, and a photo of the old seal if possible.
