The DBH 8428Sil radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 120.50 mm shaft diameter, 152.40 mm housing diameter and 15.80 mm height make it suitable for medium and large industrial equipment. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for minor misalignment. It is a wear part that should be replaced at the first sign of leakage.

This item is a radial shaft seal from the DBH brand, identified by the designation 8428Sil. Its standard dimensions are: shaft diameter 120.50 mm, housing diameter 152.40 mm and height 15.80 mm. The A 124 design corresponds to a configuration with a sealing lip and metal body, intended for press fitting into a cylindrical housing. The lip elastomer is formulated to withstand common industrial oils and greases, although the specific compatibility with your equipment's fluid must be verified before installation.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, large electric motors, conveyor rollers and power transmission equipment. In all cases it serves to confine the lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate the wear of bearings and gears. It is also used as a secondary closure on fan and industrial mixer shafts.

To correctly select a seal, three things must be verified: that the shaft diameter is within the recommended tolerance, that the housing has the appropriate diameter and depth, and that the lip material is compatible with the fluid and working temperature. During installation, the lip should be lubricated with the same grease or oil used in the equipment, inserted perpendicular to the shaft and protected from impacts that could damage the sealing edge. Misalignment is the most common cause of premature leakage.

If you need a seal with nearby dimensions or an equivalent from another brand, you can consult us. Based on the code 8428Sil or the shaft, housing and height dimensions, we look for alternatives in our seal and shaft seal lines. We can also advise you if the original design is no longer available and a replacement with a different lip geometry or material needs to be evaluated. The more data you provide — fluid, temperature, speed — the more accurate the proposal will be.
