The DBH 1294 seal is a single-lip radial seal mounted on the shaft and inside the housing to retain lubricant and block the ingress of dust, water or particles. With 44 mm shaft, 79.90 mm housing and 12 mm height, it is a size intended for gearboxes, pumps and transmission equipment where axial space is limited. MR Accesorios Industriales carries this official brand and helps you confirm the size before requesting a quote.

This item is a DBH radial shaft seal designated 1294, with the following dimensions: shaft diameter 44 mm, housing diameter 79.90 mm and height 12.00 mm. The design is Mx, a spring-loaded sealing lip that runs on the rotating shaft. The 12 mm height defines the width of the housing where the seal fits; respecting it is key so that the lip rests on the correct track and is not misaligned.

Seals of this size are used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. They also appear in older or imported machines where the housing has an uncommon size, such as the 79.90 mm in this case. Their function is twofold: keep oil or grease inside the assembly and prevent contaminants from entering that accelerate wear on bearings and gears.

For installation, verify that the shaft is clean, free of burrs or tool marks, and that the housing has no dents. Lubricate the lip with the same grease or oil as the equipment before inserting it, and do so with a tube or press that applies pressure on the outer diameter, never on the lip. If the shaft is worn, consider a nearby size or a seal with an offset lip so it seals on a new track.

If you need an equivalent or a nearby size, send us part number 1294 along with the shaft, housing and height dimensions, and a photo of the old seal if you have it on hand. The part number engraved on the seal or the equipment model also helps. With that data we search for alternatives within the DBH line or other brands we carry, and provide a quote.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals. If you already have the part number, write to us on WhatsApp and we will reply with a quote. If you are still measuring, send us the dimensions and we will help you identify the seal that corresponds to your equipment.
