The DBH 5818Vit is a radial shaft seal that keeps oil or grease contained between a rotating shaft and its housing. It measures 12 mm on the shaft, 22 mm on the housing and 7 mm in height, and it uses the Lz design. You will find this size in gearboxes, pumps, electric motors and transmission equipment, where it holds lubricant in and keeps dust and water out. MR supplies this brand and can help you confirm the right choice.
The 5818Vit belongs to the DBH line of radial shaft seals. Its dimensions are shaft diameter (d) 12.00 mm, housing diameter (D) 22.00 mm and height (h) 7.00 mm. The Lz design means a sealing lip with a spring and a metal case, made for rotating shafts that run with lubrication. The elastomer lip rides on the shaft while the outer case presses into the housing, which holds the seal centered and in place.
Seals in this size range show up on equipment with small shafts: electric motors, centrifugal pumps, gearboxes, gear cases, compressors and machine tools. You will also see them on agricultural implements and transmission lines where oil has to stay in and dirt has to stay out. In all of these, the seal does two jobs at once: it retains lubricant and it blocks outside contaminants.
During installation, inspect the shaft for burrs or wear and make sure the surface under the lip is smooth. Apply lubricant to the lip before fitting the seal, and drive it in with a tube that presses on the outer diameter, never on the lip itself. When you select a replacement, account for shaft speed, operating temperature and the fluid being sealed. If the shaft or housing is damaged, an alternative design may be the better route.
For an equivalent, send part number 5818Vit with the shaft and housing dimensions, a photo of the part and the fluid type. With those details we can search the DBH line for a match. We can also tell you whether a different height will work or whether the housing can take a seal with a larger cross section.
