The DBH 5637 is a radial shaft seal built around a 40 mm shaft, a 56 mm housing bore and a 10 mm height. It keeps lubricant where it belongs and blocks dust, water and particles from reaching the bearing or bushing area. Pressed into the housing and running against the shaft, it creates the dynamic barrier that industrial drives depend on.

Part number 5637 belongs to the DBH seal line. The three values that define it are shaft 40 mm, housing 56 mm and height 10 mm, and the Mr designation describes how the lip and body are put together. Treat it as a drop-in replacement only when those dimensions already match your assembly. If the shaft or the bore is off, forcing the seal in will leave the lip unable to do its job.

You will find seals like this one in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment, as well as in machine tools, agitators and lubrication systems where rotation never stops. In every case the seal shields the bearing or bushing and holds lubrication at the contact point, which keeps the assembly running longer and cuts downtime.

Selection starts with the three dimensions, but the running surface matters just as much. A shaft with scratches, wear or burrs will not let a new lip seal properly, even when the sizes are right. At installation, coat the lip with the same oil or grease the equipment uses, seat the seal perpendicular to the housing, and avoid hammering the metal body out of shape.

If 5637 is not the number you need, send a message on WhatsApp and the team will look for an equivalent. We compare designation, dimensions and lip type to match your equipment. The catalog covers the DBH brand and other seal lines, so a compatible option is usually within reach.
