DBH 5442 radial shaft seal — 150 x 180 x 13

DBH 5442 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 5442 and any equivalents.

A radial shaft seal from the DBH line, designation 5442, sized for a 150 mm shaft, a 180 mm housing bore and a 13 mm height. Its Lx design means a sealing lip in a profile built for standard housing seats. This is the kind of part a maintenance team reaches for when lubricant is escaping or contaminants are working their way into a rotating assembly.

Reading the code is straightforward: 5442 identifies the item, and the three figures that follow in the catalog entry describe the fit — shaft 150 mm, housing 180 mm, height 13 mm. Confirm all three against your equipment before ordering, since a seal that is correct in two dimensions and off in the third will not seat properly.

Typical service locations include centrifugal pumps, electric motors, gearboxes, conveyor rollers and machine tools, wherever a shaft turns at moderate speed with oil or grease present. In plant maintenance and repair workshops, these seals are replaced as wear allows lubricant past the lip, which puts bearings at risk if it goes unaddressed.

Installation calls for a clean shaft and bore, free of burrs and scratches. Coat the lip with the same oil or grease used in service, then press the seal in squarely using a tube or press that contacts the outer ring only — never the lip. Where the shaft surface is already worn, a taller seal may be the better choice.

For an equivalent, send code 5442 along with your shaft, housing and height measurements. We can also work from standard dimensions or from an original manufacturer's code. MR manufactures split plummer block housings, roller chains and sheaves in-house, so we can point you toward a suitable option for your equipment.
