The DBH 9056 is a radial shaft seal with a 9 mm shaft, 30 mm housing, and 7 mm height. It keeps lubricant in and contaminants out of rotating equipment, running on the shaft. Common in gearboxes, pumps, motors, and transmission assemblies where space is tight and a dependable seal is required.

The part number itself gives the size: shaft 9 mm, housing 30 mm, height 7 mm. The Lx design indicates a single lip with a spring, intended for lubricated rotating shafts. The elastomeric lip contacts the shaft while the spring maintains pressure; the outer body presses into the housing. As a wear item, the lip can harden or score over time, leading to oil loss.

These seals are found in compact equipment with small shafts and limited housing space: small electric motors, centrifugal pumps, gearboxes, fans, machine tools, and power transmission units. They also appear in agricultural applications and general maintenance, where replacing the seal protects bearings or bushings from lubricant escape and dust ingress.

Selection requires matching the shaft diameter, housing bore, and height to the original. Inspect the shaft surface for burrs, wear, or a visible track; a damaged shaft will prevent the new lip from sealing. During installation, lubricate the lip, seat the seal squarely, and tap on the outer edge only, never on the lip. If the shaft is worn, consider a wear sleeve or a different size.

If the 9056 is not the exact size, provide the old code, a photo, or caliper measurements. We can locate a size within the same series or an equivalent from another brand, confirming against the manufacturer's data before quoting. We also supply seals for worn shafts and unusual housing tolerances.
