The DBH 1098 radial shaft seal is a lip seal that keeps lubricant in and contaminants out of rotating equipment. It is identified by part number 1098 and the A 077 design, which defines the lip geometry and case style for single-direction rotation with oil or grease lubrication. Its dimensions are shaft 88.90 mm, housing 122.98 mm and height 22.96 mm. Verify these three dimensions on your equipment before installation.
This seal is a direct replacement when the original matches the same three dimensions: shaft diameter d 88.9 mm, housing diameter D 122.98 mm and height h 22.96 mm. The A 077 design covers the lip profile and case type. Because sizes are specific, confirm your shaft and housing measurements; a small difference means the seal will not seat or seal correctly.
Seals of this size are common in industrial gearboxes, centrifugal pumps, large electric motors, conveyor rollers and belt or chain drive equipment. They also appear on mixer, fan and compressor shafts that run at moderate peripheral speeds. The job is always the same: retain the lubricant and block dust, water or particles that would otherwise shorten bearing life.
Installation matters as much as the part number. Inspect the shaft for burrs or deep marks in the lip contact area and make sure the housing is clean and undistorted. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in with a flat driver on the outer diameter, never on the lip. The 22.96 mm height should sit flush or slightly recessed per the housing design. If the shaft is worn, consider a repair sleeve or a different size.
If you need an equivalent, send part number 1098 or your measured shaft and housing dimensions. We can look for an alternative within the DBH line or from other brands we supply, keeping tolerances and lip type in mind. We can also help if your original seal carries a different designation but matches the main dimensions.
