The DBH 5030 is a radial shaft seal used to retain lubricant and block contaminants at the point where a shaft exits a housing. It is press-fitted into the bore and rides on the shaft with a flexible lip. As a wear component, it is replaced when leakage or ingress occurs.

This seal carries part number 5030 from DBH. Key dimensions: shaft 20.00 mm, bore 47.00 mm, width 10.00 mm. The Lz designation defines the lip and case geometry. These three values locate the seal in the housing and ensure the lip contacts the shaft properly. If the shaft or bore is worn, the seal may not seat correctly even with matching dimensions.

Typical applications include gearboxes, pumps, electric motors, rollers, and power transmission equipment. The seal retains oil or grease while keeping out dust, washdown water, and debris. In dirty or wet environments, it is the first line of defense for bearings and gears.

When selecting, verify shaft surface condition, roughness, housing concentricity, and speed. A scratched or burred shaft can ruin the lip quickly. During installation, lubricate the lip, insert perpendicular to the shaft, and press on the outer ring only. Respect the lip orientation of the Lz design.

For an equivalent, send the old part number, shaft and housing dimensions, and a photo via WhatsApp or email. We can confirm if the DBH 5030 is correct or suggest another design, including options with an additional lip or spring. The more data provided, the faster the identification.
