The DBH 9319 is a radial shaft seal built to keep lubricant in and contaminants out of rotating assemblies. Its size is defined by a 5 mm shaft, a 16 mm housing bore and a 6 mm height, and it uses the Ls lip configuration. Because the sealing lip is a wear item, the seal is normally replaced once it hardens or starts to weep. MR supplies this brand and helps match the part to the application.

Reading the reference: 9319 identifies the seal in the DBH line, while the dimensions follow the usual d x D x h order. Here d is 5 mm, D is 16 mm and h is 6.00 mm. The Ls designation describes a single lip with a spring, oriented for a lubricated rotating shaft. Lip geometry and direction matter because the sealing edge has to sit against the correct face of the shaft.

Seals in this size range show up in small electric motors, water pumps, gear reducers, compressors and transmission components. Two jobs are always in play: holding oil or grease inside the housing and keeping dust, water and other matter out. Fan shafts, machine tools and industrial laundry equipment are other places where this type of seal is used and where moisture or washdown makes reliable sealing important.

Before fitting, confirm that the shaft and housing match the stated dimensions. The shaft should be clean and free of burrs or scratches, and the housing chamfer should be intact. Apply lubricant to the lip, then press the seal in with a tube or arbor press that bears on the metal case, not on the lip. If the shaft is worn, an offset lip may be worth considering.

To quote part number 9319, or to match an old seal, send the shaft diameter, housing diameter and height. A photo of the seal and its housing also helps. From that information we can check alternatives in the DBH line or in other brands we carry, while keeping the fit tolerances in mind. Approximate dimensions are risky: a seal that is slightly off can leak at the lip or fail to seat in the bore.

For a quote on the DBH 9319 oil seal, message us on WhatsApp with the part number or the dimensions. We can help you select the right seal for the shaft, speed and lubricant involved. If the Ls design or the mounting direction is unclear, ask before ordering so the replacement goes in correctly.
