A radial shaft seal in the DBH line, the 1400 designation covers a single-lip seal that sits in the housing bore and rides on the rotating shaft, keeping lubricant in and contaminants out. Its three working dimensions are 22 mm at the shaft, 36 mm at the housing and 6.00 mm in height, which places it among the smaller seals used in pumps, compact motors, gearboxes and power transmission assemblies. The Lz configuration pairs a spring-loaded elastomeric lip with a metal outer case that presses into the seat.

Reading the designation is straightforward: 1400 identifies this size, while the numbers behind it describe the fit. Shaft 22 mm, housing 36 mm, height 6.00 mm. The lip contacts the shaft and the metal case holds the seal in the bore, so the elastomer does the sealing and the case does the locating. In service the part performs two jobs at once, holding oil or grease where it belongs and blocking dust, water and particles from reaching the bearings behind it.

You will run into this size on small centrifugal pumps, low-power electric motors, speed reducers, fan shafts, machine tools and general power transmission equipment, as well as gearboxes and conveyor rollers. Because the lip wears against the shaft, the seal is a consumable item. Oil weeping at the housing, grease thrown onto nearby surfaces or a change in shaft noise are the usual signs that it is time to look at it.

Installation rewards care. The shaft should be clean, free of burrs and marks, with a sealing surface of the right roughness. Drive the seal in with a tube or driver that contacts the metal case only, never the lip, and coat the lip with the same oil or grease the equipment runs on before you seat it. Confirm that the 36 mm bore and 6 mm depth match the seat. Where the shaft itself shows wear, a seal positioned with the lip on a fresh area can be considered.

For an equivalent or another size, send code 1400 along with the shaft, housing and height readings from the nameplate or drawing. That is enough for us to search the DBH line or the other brands we supply. If the original carries a similar but not identical designation, we can help sort out the difference. Dimensions, lubricant type and operating temperature all sharpen the recommendation.
