The DBH 5709 radial shaft seal is a lip seal mounted on the shaft to retain lubricant and block the entry of dust, water or particles in gearboxes, pumps and rotating equipment. Its designation 5709 corresponds to a specific size of 44.45 mm shaft, 81 mm housing bore and 11.90 mm height, with Lx design. At MR Accesorios Industriales we offer it as part of our seals and oil seals line for maintenance and replacement.

This item is a DBH 5709 radial shaft seal, identified by part number 5709. Its dimensions are 44.45 mm shaft diameter (d), 81 mm housing bore (D) and 11.90 mm height (h). The Lx design corresponds to a single-lip configuration with spring, suitable for rotating shafts. The DBH brand is an official brand carried by MR, so the seal arrives with its designation and factory traceability.

Typical applications for a seal of this size include gearboxes, reducers, centrifugal pumps, electric motors and transmission equipment where oil or grease must be contained and external contamination avoided. It is also used on fan, mixer and conveyor shafts. Its 11.90 mm height profile allows it to be mounted in housings with limited space, provided the shaft diameter and bore match the stated dimensions.

To install the DBH 5709 oil seal, check that the shaft has the 44.45 mm diameter and the housing the stated 81 mm. Check that the shaft surface shows no burrs or excessive wear; a scored shaft accelerates lip failure. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and fit the seal perpendicular to the shaft, without striking it directly. If the housing has a chamfer, follow the angle so as not to damage the seal.

If you need an oil seal equivalent to the 5709 or a nearby size, send us the full part number, the shaft, housing and height dimensions, and a photo of the old seal if possible. We can also help you identify the series or design if it does not exactly match the Lx. At MR Accesorios Industriales we work with official brands and in-house manufacturing, and we advise you so that the replacement is the correct one.
