The DBH 8900 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering rotating shafts. With dimensions of 40 mm shaft diameter, 62 mm housing bore and 7 mm height, it is press-fitted into the housing and runs on the shaft with a flexible lip. It is a common wear part in gearboxes, pumps, electric motors and power transmission equipment, where sealing protects bearings and gears.

This DBH 8900 oil seal has an Lx design and standard dimensions: shaft diameter (d) of 40 mm, housing bore diameter (D) of 62 mm and height (h) of 7.00 mm. The sealing lip, generally made of elastomer, presses against the shaft with slight interference to retain oil or grease. The outer metal case ensures a firm fit in the housing. It is a standard component in the radial shaft seal category, intended for rotating shafts with continuous or intermittent motion.

Typical applications include gearboxes, reducers, centrifugal pumps, electric motors, compressors and belt- or chain-driven transmission equipment. In all these cases, the oil seal prevents lubricant leaks and the entry of dust, water or particles that accelerate wear on bearings and gears. It is also used in machine tools, industrial washing equipment and conveyor systems, where lubricant cleanliness is critical to the service life of the assembly.

To select an oil seal correctly, verify that the shaft, housing bore and height dimensions match those of your equipment's housing and shaft. The shaft surface must be ground and free of grooves to avoid damaging the lip. During installation, lubricate the lip and use an installation tool that presses on the outer diameter, never on the elastomer. If the shaft shows wear, consider an adjacent size or a seal with an auxiliary lip. Peripheral speed and operating temperature determine the lip material; contact us if you have any doubts.

If you need an equivalent or an adjacent size, send us the code 8900 or your current dimensions (shaft diameter, housing bore and height) via WhatsApp. At MR Accesorios Industriales we check your inquiry against the manufacturer's data sheet to offer you the closest option. We can also advise you on the type of elastomer or lip design for your application. Request a quote for your DBH 8900 oil seal or its replacement directly through that channel.
