The DBH 8879 is a radial shaft seal that keeps lubricant in and contaminants out of rotating shaft assemblies. With a 25 mm shaft diameter, 43 mm housing bore and 8.00 mm height, it fits compact equipment such as pumps, electric motors, gearboxes and transmission drives. MR Industrial Accessories supplies this brand and can help you confirm the correct seal for your application.

This seal carries the designation 8879 and the Lx design, which means it has a sealing lip with a spring for lubricated rotating shafts. The dimensions are: shaft 25 mm, housing bore 43 mm, height 8.00 mm. These three values determine interchangeability, so always compare them with the shaft and housing before replacing a seal.

Seals of this size are common in centrifugal pumps, low and medium power electric motors, gear reducers, mixers and power transmission equipment. Their job is to prevent oil or grease from escaping and to block dust, water and particles that would otherwise speed up wear on bearings or bushings. Treat it as a wear part: replace it when you see leaks or hear unusual noise.

During installation, inspect the shaft for burrs or splines that could cut the lip. Lubricate the seal before sliding it into place and use a tool that presses on the outer diameter, never on the lip. When selecting a seal, consider shaft speed, operating temperature and the lubricant in use. If your original seal has a different code, we can search for an equivalent with the same dimensions.

To request a replacement for the DBH 8879, send the code or the dimensions (25 x 43 x 8 mm) via WhatsApp or email. We can also quote alternatives from other brands or with slight dimensional variations if the housing allows. MR Industrial Accessories helps you identify the right part and complete your purchase efficiently.
