The DBH 8511Pol oil seal is a single-lip radial shaft seal with a metal case and elastomer, designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 52 mm shaft diameter, 70 mm housing and 8.50 mm height make it suitable for gearboxes, pumps and medium-sized electric motors. At MR Accesorios Industriales we carry it as part of our seals and oil seals line, with technical advice so you can choose the correct variant for your application.

This item is a DBH 8511Pol radial shaft seal, identified by its designation 8511Pol. Its main attributes are: shaft diameter (d) of 52 mm, housing diameter (D) of 70 mm and height (h) of 8.50 mm. The Lx-R-H design indicates a single-lip configuration with spring, outer metal case and elastomer resistant to oils and greases. These standard dimensions allow you to replace worn seals in equipment operating with 52 mm shafts and 70 mm housings, maintaining sealing under continuous rotation conditions.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, the oil seal serves to prevent lubricant leaks and the ingress of dust, water or particles that accelerate wear on bearings and gears. It is commonly found in food and textile industrial machinery, or in process equipment where a reliable barrier is required between the lubricated interior and the outside environment.

To install this oil seal correctly, verify that the shaft diameter is within the recommended tolerance and that the contact surface is smooth and free of burrs. The housing must be clean and undamaged; suitable roughness favors sealing. During installation, lubricate the lip with the same service oil or grease and avoid striking it. If the equipment runs at high peripheral speed or elevated temperatures, contact us to evaluate an alternative elastomer compound or a design with additional reinforcement.

If you need an equivalent from another brand, you can send us the code 8511Pol or the exact dimensions of your oil seal (shaft diameter, housing and height). We can also help if space is limited and you require a lower height or a double-lip design. At MR Accesorios Industriales we advise you so that the selection is the correct one.
