The DBH 5130 is a radial shaft seal built to keep lubricant where it belongs and to shut out dust, water and other contaminants. Its Lx design uses a single lip with a spring, so it seals along one direction of rotation. You will find it in gearboxes, pumps, motors and transmission assemblies. Reading the code correctly is the first step toward a proper replacement.

The designation 5130 tells you the size: shaft 30 mm, housing 52 mm, height 10 mm. The lip rides against the rotating shaft, while the outer diameter presses into the housing bore to form a static seal. The spring behind the lip keeps contact pressure steady as the shaft turns.

This seal shows up in gearboxes, centrifugal pumps, electric motors, reducers and conveyor rollers. Its job never changes: hold oil or grease inside the assembly and block particles that would otherwise shorten bearing and gear life. That makes it a common item on preventive and corrective maintenance lists.

Before ordering, check that the shaft diameter falls within the recommended tolerance for radial seals and that the housing bore is smooth and free of burrs. Lubricate the lip before pressing it in, and use a tool that will not nick the sealing edge. For high peripheral speeds or elevated temperatures, ask about other compounds and geometries.

If you need code 5130 or the size 30 x 52 x 10 mm, send us an equivalent from another brand and we will come back with compatible options. We can also source a different design, such as a double lip or a specific elastomer, when the application calls for it. The DBH brand is part of our seals and oil seals line.
