DBH 1370 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 1370 and any equivalents.

A radial shaft seal such as the DBH 1370 keeps lubricant where it belongs and keeps dust, water and particles out. It works as a lip seal: the outer diameter holds in the housing while the lip runs against the rotating shaft. The 1370 designation covers a shaft of 33 mm, a housing bore of 44 mm and a height of 8.00 mm, in Mt design. MR Industrial Accessories supplies this brand and quotes by part number.

Read the code first. The 1370 number identifies the size combination, and the three values to confirm are shaft 33 mm, housing bore 44 mm and height 8.00 mm. The Mt designation describes how the lip and metal body are built, a configuration suited to rigid housings and shafts that turn continuously. The elastomer lip presses lightly on the shaft, and the outer diameter stays seated in the bore.

Because it is a wear part, the seal eventually tells you it is done: the lip stiffens or picks up marks and oil starts to escape. That is the moment to look at it, ideally whenever the equipment is opened for service. You will find this size in gearboxes and gearmotors, centrifugal pumps, electric motors, rollers and other transmission equipment, as well as machine tools, mixers and conveyors. In each case it does two jobs at once: it holds oil or grease in and keeps contaminants away from bearings and gears.

Installation decides whether the replacement lasts. Wipe the housing and shaft clean, look for burrs or tool marks, and coat the lip with the grease or oil the equipment already uses. Drive the seal in square, using a tube or shim that bears on the outer diameter, and never strike the lip. When you select a replacement, match all three dimensions and the design type. If the shaft itself shows wear, a sleeve or a seal with the lip in a different position may be the better route. Correct dimensions with a poor fit still leak.

For an equivalent, send the 1370 code together with the shaft, housing and height measurements, and a photo of the old part if you have one. With that information our team reviews the DBH line and the options that fit your equipment. We can also advise when the housing has a shoulder, when the shaft is worn, or when a variant with a material for higher temperatures is needed.
