For rotating shafts, the DBH 6291 radial shaft seal provides a single sealing lip in a metal case. It measures 27 mm at the shaft, 55 mm at the housing and 8 mm in height, so it keeps lubricant in and keeps dust, water and particles out. Gearboxes, pumps, motors and transmission equipment commonly use this size. We supply the DBH line and can help you confirm the right seal for your equipment.

The DBH 6291 carries the code 6291 and uses the Ls design: one sealing lip with a metal outer case, made for lubricated rotating shafts. Before you order, verify three dimensions: shaft diameter 27.00 mm, housing diameter 55.00 mm and height 8.00 mm. These three values decide whether the seal fits your assembly.

You will find seals of this size in gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In every case the job is the same: hold oil or grease inside and keep contaminants outside. Treat it as a wear part and replace it when you see a leak, or when the lip feels stiff or shows cuts or visible wear.

During installation, inspect the shaft for burrs or marks that could harm the lip. Coat the lip with the same oil or grease the equipment uses, then press the seal in perpendicular to the shaft without uneven hammer blows. If the housing has a chamfer, follow its angle so the lip does not roll inward. Lip and spring material should match your temperature, speed and fluid; if you do not have those figures, ask us and we will help you work them out.

To quote an equivalent, send code 6291 with your shaft, housing and height dimensions plus the working conditions. With that information we look at alternatives in the DBH line or other brands we supply, and we confirm whether the Ls design suits your equipment or whether a different lip or case style works better.

We supply the DBH brand. To request a quote, message us on WhatsApp or email with code 6291 and your equipment dimensions. We reply promptly with the option that fits your application.
