Sealing a rotating shaft comes down to matching three measurements and one design detail. The DBH 9508Vit oil seal covers a 75 mm shaft, a 100 mm housing bore and a 10 mm width, and it is built in the Lz-Bidi configuration. That means two lips work the sealing edge: one holds the lubricant inside, the other keeps dust and moisture out. Gearboxes, pumps and electric motors are the usual homes for this part, and the elastomer handles mineral oil and the temperatures found in normal plant service. It belongs to the seals and oil seals line we supply.

Reading the code helps when you reorder. DBH is the brand, 9508Vit is the item reference, and the Lz-Bidi designation tells you the lip arrangement before you even open the box. On the dimensional side the numbers run shaft 75.00 mm, housing 100.00 mm, width 10.00 mm. Any of those three can be the one that rules a part in or out, so it pays to measure the worn seal and the shaft seat rather than trust an old purchase order.

Where does a double lip earn its place? Gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tool spindles all run shafts that must stay lubricated and clean. In dusty or damp areas a single lip often lets grit past the edge, and that grit ends up in bearings and gear teeth. The secondary lip on this seal gives the dirt somewhere to stop. Power transmission units and hydraulic equipment turning at moderate speeds are common users as well.

Installation decides how long the seal lasts. The housing bore should be clean and free of burrs, and the shaft needs a fine finish with enough surface hardness. Wipe the lip with the same oil or grease the equipment runs on, then press the seal in squarely until it seats. A worn shaft groove is worth addressing, either with a wear sleeve or by replacing the shaft. Speed, temperature and lubricant type all feed into seal selection, and our technical team can walk through those with you.

If you are cross-referencing, the fastest route is to send the code 9508Vit or the three measurements from your equipment. From there we can look at other brands and series that do the same job. Tell us too if the mounting space is tight or if the environment calls for a material suited to high heat or chemicals. Quote requests go through WhatsApp or email with the part number, and we answer promptly with options and equivalents.
