The DBH 5430 is a radial shaft seal, a lip seal that keeps oil or grease contained between a rotating shaft and its housing. It measures 7.93 mm at the shaft, 25.37 mm at the housing bore and 9.52 mm in height, and it comes in the Lz design. You will find it in gearboxes, pumps, electric motors and power transmission equipment, where it holds lubricant in and keeps dust and water out.

This seal belongs to the DBH line and is identified by part number 5430. Its three key dimensions are a shaft diameter (d) of 7.93 mm, a housing diameter (D) of 25.37 mm and a height (h) of 9.52 mm. The Lz designation refers to the lip and metal case geometry, made for shafts that turn under permanent lubrication. It is a standard replacement item in the seals and oil seals category that MR Industrial Accessories supplies.

Seals in this size range are common in compact machinery: small electric motors, gearboxes, water and oil pumps, compressors, machine tools, and belt or chain drives. In each of these, the seal does two jobs at the same time. It keeps the lubricant where it belongs, and it blocks contaminants from working their way in from outside, which is one of the most frequent reasons bearings and bushings fail early.

Installation calls for a few basic checks. The shaft should be free of burrs or marks where the lip makes contact, and the housing must be clean and not deformed. Put some lubricant on the lip before you push the seal in, and seat it fully and square, without hitting it from the side. When you pick a replacement, look beyond the three dimensions at the lip design, the material and the fluid being sealed, since those factors drive how long the part lasts.

If you are after an equivalent, send part number 5430 along with the shaft and housing dimensions, a photo of the old seal and the equipment it came from. With that information we search for an alternative in the DBH line or in other brands we supply, and we quote you on WhatsApp.
