The DBH 1340 oil seal is a single-lip radial shaft seal that mounts on a 73.42 mm shaft and fits into a 110.20 mm bore, with a 9.00 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in rotating equipment where the shaft turns inside a fixed housing.

This item is identified by the designation 1340 and corresponds to an oil seal with design A 193. The dimensions you need to verify before ordering are: shaft diameter 73.42 mm, housing diameter 110.20 mm and height 9.00 mm. The A 193 design defines the geometry of the lip and the metal case, so do not replace it with another design even if the outer dimensions match: the contact on the shaft and the sealing performance change.

Radial shaft seals of this type are used in gearboxes, pumps, electric motors, mixers and transmission equipment where there is a shaft rotating inside a lubricated housing. They also appear in older or imported machines where finding the exact size is complicated. If the shaft is scored or the housing has play, the new seal will not seal properly no matter how correct the dimensions are.

To install it, clean the housing and the shaft, check that there are no burrs or deep marks, and lubricate the lip with the same grease or oil used in the equipment. Insert the seal perpendicular, without striking the lip, using a tube or shim that rests on the outer ring. If the housing has a shoulder, respect the seating depth. A misaligned seal leaks on one side even if the dimensions are correct.

If you cannot find the exact size or the code 1340 does not appear on your list, send us the shaft, housing and height dimensions along with a photo of the old seal. At MR Accesorios Industriales we can look for a nearby size or an equivalent within the same seal category. The more data you provide, the faster we can confirm whether there is a replacement.
