The DBH 9125 is a radial shaft seal built for rotating shafts. It keeps lubricant in and contaminants out. With a shaft diameter of 28 mm, housing diameter of 50 mm, and height of 10 mm, it presses into the housing and seals against the shaft via a flexible lip. As a wear part, it is typically replaced during scheduled or corrective maintenance.

This oil seal follows the Lx design, which means a single sealing lip with a retaining spring. The dimensions are shaft 28 mm, housing 50 mm, and height 10 mm. The Lx configuration is a standard choice for rotating shafts that require lubrication. DBH is a brand we supply, and we can also suggest equivalent seals from other manufacturers.

Radial shaft seals like the DBH 9125 are common in gearboxes, pumps, electric motors, conveyor rollers, and power transmission equipment. Their role is to hold oil or grease inside the assembly and keep dust, water, and particles away from bearings. In dirty or wet environments, a proper seal helps extend the life of internal components and reduces unplanned downtime.

When selecting a replacement, confirm that the shaft, housing, and height dimensions match the original. The shaft surface should be ground and sufficiently hard to avoid early lip wear. During installation, lubricate the lip with the same lubricant used in the equipment and use a tool that presses on the outer diameter, not on the lip. Avoid hitting the seal with sharp objects.

If you need a cross-reference to another brand, we can help. We carry a wide range of seals and oil seals and can guide you based on your shaft and housing dimensions. We also offer installation tools and compatible lubricants. To speed up the process, have the original part number or the exact dimensions ready.
