The DBH 1340 is a single-lip radial shaft seal built for a 73.42 mm shaft running in a 110.20 mm housing bore, with a 9.00 mm height. Its job is to hold lubricant in place and keep dust, water and particles out of the assembly, since those contaminants speed up wear on bearings and bushings. You will find this type of seal in rotating equipment where a shaft turns inside a stationary housing.

The code 1340 identifies this seal, and its design is A 193. Before you order, confirm three figures: shaft 73.42 mm, housing 110.20 mm, height 9.00 mm. The A 193 design sets both the lip geometry and the metal body, so a seal with matching outer dimensions but a different design is not a valid swap, because the way it contacts the shaft and seals will differ.

Seals in this category show up in gearboxes, pumps, electric motors, mixers and transmission assemblies, as well as on older or imported machines where the exact size can be hard to source. Keep in mind that a scored shaft or a housing with play will prevent proper sealing, regardless of how accurate the dimensions are.

During installation, clean the shaft and housing first and look for burrs or deep marks. Coat the lip with the same oil or grease the equipment uses. Press the seal in squarely, using a tube or spacer that bears on the outer ring rather than the lip, and never strike the lip itself. Where the housing has a shoulder, seat the seal to the correct depth. A seal that goes in crooked will leak on one side even when the size is right.

If the size you need is not on your list or the code 1340 does not appear, send the shaft, housing and height measurements together with a photo of the old seal. MR Industrial Accessories can search for a matching size or an equivalent within the same seal category. The more details you send, the quicker we can point you to the right replacement.

For a quote on the DBH 1340, message us on WhatsApp with the code and the dimensions. If you are unsure about the design or the lip material, ask before you buy, since a seal with the wrong lip can fail in a short time. Technical questions are handled Monday through Friday.
