The DBH 8270 is a radial oil seal sized for a 17 mm shaft, a 30 mm housing bore and a 7 mm height. Its Lx profile is a single lip with spring, built for rotating shafts where lubricant has to stay in and dust or water has to stay out. You will find it in pumps, electric motors, gearboxes and transmissions. MR Industrial Accessories supplies it within its seals and oil seals range and can help you confirm the size before you order.

This seal carries the DBH designation and the code 8270. Reading the dimensions in order: shaft 17 mm (d), housing 30 mm (D), height 7 mm (h). The Lx execution means one lip with a spring, which is the usual choice for rotating shafts that run with oil or grease. DBH is one of the brands MR supplies, so the part keeps its original marking and can be cross-checked against the manufacturer's data if your records require it.

Seals in this size range turn up in low and medium power equipment: centrifugal pumps, small electric motors, gearboxes, compressors, fans and machine tools. They do two jobs at once: they hold the oil or grease inside the housing and they keep outside contamination from getting in. In areas with dust, chips or moisture, the seal works together with the bearing and helps the whole assembly last.

When fitting one, look at the shaft first: the surface should be hard enough and smooth, with no burrs or score marks. Put some of the same oil used in the equipment on the lip before you push the seal in, and set it square to the shaft instead of hitting it directly. If the housing seat is worn, a taller seal may be the answer. Speed, temperature and the fluid being sealed all affect the choice, and with those details the right option can be confirmed.
