The DBH 8778 is a radial shaft seal that keeps lubricant inside the housing and keeps dust and moisture out along a rotating shaft. It is press-fitted into the bore and rides on the shaft, with a shaft diameter of 11.50 mm (d), a housing diameter of 24.00 mm (D) and a height of 10.00 mm (h). The Lx design uses a single sealing lip with a spring, which suits places where there is little room along the shaft axis.
Reading the code helps you order the right part. The 8778 number identifies this seal in the DBH line, and the three figures in the size string follow the usual order: shaft first, then housing bore, then height. So the numbers tell you what the shaft measures, what the bore measures and how much axial room the seal needs.
The lip is made of an elastomer and sits on a metal outer case that holds its shape in the bore. That combination is what gives the seal its job: holding oil or grease in and blocking contaminants from working their way in along the shaft.
You will find this type of seal on rotating equipment such as gear reducers, centrifugal pumps, electric motors, compressors, transmission shafts and farm machinery. It also shows up in automotive work and in industrial machines running at moderate temperatures and at peripheral speeds that stay inside the normal range for this kind of seal.
Before ordering, confirm the three dimensions against the old part or the drawing. The shaft surface should be ground and hard enough for the lip to run on, the lip should get a little lubricant before it goes in, and a proper installation tool keeps the lip from being nicked or rolled during fitting.
If your application calls for a different size or a close variant, send the 8778 number or the exact dimensions you measured. We supply alternatives from other brands and can help you sort out the right choice based on the fluid, the temperature and the rotation speed involved. Quotes go through WhatsApp or email, and we answer quickly.
