When you need to replace a radial shaft seal, the DBH 5128Sil is a lip seal that fits into the housing and seals against the rotating shaft. It keeps lubricant in and blocks dust, water, or particles from entering. With a 48 mm shaft, 72 mm housing, and 7 mm height, and an Lx design, it works well in industrial equipment where axial space is tight. MR supplies this seal as part of its seals and oil seals line.

This radial shaft seal from DBH is coded 5128Sil. The dimensions are 48 mm for the shaft, 72 mm for the housing, and 7.00 mm for the height. The Lx design means it has a sealing lip and a metal case, made to be press-fitted into the housing. The lip runs against the shaft with controlled interference to create a dynamic seal. It is a standard replacement part in the seals and oil seals category.

You will find seals like the 5128Sil in gearboxes, pumps, electric motors, conveyor rollers, and power transmission equipment. Their job is to protect bearings and gears from outside contamination and to stop oil or grease from leaking. They also appear in agricultural machinery, washing equipment, and hydraulic systems where a shaft turns inside a fixed housing. The compact size helps in tight spaces.

To choose the right seal, check that the shaft, housing, and height match your equipment. The Lx design points to a specific lip and case geometry; if your original assembly uses a different setup, ask our technical team. When installing, lubricate the lip with the same oil or grease used in the equipment, push the seal in straight, and avoid hitting the lip. Misalignment or a scratched shaft will cause early leaks.

If you need an equivalent to the 5128Sil, the easiest way is to send us the full code, a photo of the part, and dimensions taken with a caliper. With that information, we can look for an alternative in the DBH line or other brands we carry. We can also help if the housing diameter is slightly different or if the available width does not allow the standard height. Our goal is to keep your equipment running.
