When a shaft seal starts weeping, the fix is usually a direct replacement. The DBH 1135 is a spring-loaded, single-lip radial oil seal sized for a 50 mm shaft, a 64 mm housing bore, and an 8 mm width. That puts it in the range of medium-duty gearboxes, pumps, and similar rotating equipment. As a wear item, it gets swapped out once the lip hardens or leakage shows up. MR Industrial Accessories supplies this seal to maintenance and purchasing teams across the US and Latin America.

The DBH 1135 follows the Lx-R H configuration: an elastomeric sealing lip backed by a garter spring, with a metal outer case that presses into the housing. The lip rides against the rotating shaft while the spring keeps steady contact pressure. In service, that arrangement holds oil or grease in and keeps dust and water out. You will find seals of this type in gear reducers, centrifugal pumps, electric motors, conveyor rollers, and other assemblies with a turning shaft.

Because the seal is a wear part, its condition matters more than its appearance. If the equipment runs with high vibration or elevated temperatures, inspect the lip more frequently. A hardened, cracked, or worn lip lets lubricant escape and allows particles to reach the bearings and gears. Replacing the seal before that happens helps protect the rest of the assembly.

Before installation, inspect the shaft for burrs, scratches, or a worn groove in the lip contact area. The housing bore should be clean and undistorted. Apply a light film of lubricant to the lip, then press the seal in squarely—never hammer it in at an angle. When choosing a replacement, match the dimensions first, then consider the fluid type, operating temperature, and shaft speed.

If you do not have the original part number, send us the old seal's dimensions—shaft diameter, housing bore, and width—or the number 1135. We will check the DBH line and look for compatible alternatives. We can also help if the housing has a shoulder or the shaft shows wear. The more details you provide, the faster we can identify the right part.
