The DBH 1187Pol is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. With a 34.90 mm shaft, 52 mm housing bore and 10 mm width, it fits common gearbox, pump and power transmission applications. MR Industrial Accessories supplies this brand and helps you match the right seal to your assembly.

Reading the number helps with selection. The 1187Pol designation identifies the seal, while the dimensions are stated as shaft 34.90 mm, housing 52 mm and width 10 mm. The Lx-R H configuration combines a sealing lip with a dust lip, so the seal works with oil or grease on one side and guards against dust and water on the other. The lip runs against the shaft and forms the dynamic barrier that stops leakage.

Seals of this type appear in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other transmission equipment. They do two jobs at once: hold the lubricant inside the housing and block outside particles that would otherwise shorten bearing and gear life. In maintenance terms, a failed seal is a common cause of unplanned downtime, which is why replacing it with the correct size matters.

Installation calls for a clean shaft free of burrs and marks, and a housing bore that matches the stated diameter. Lubricating the lip before pressing the seal in place helps it seat without damage. The 10 mm width tells you how much axial space the housing must provide. If the application runs at elevated speed or temperature, contact MR to review the lip material and elastomer choice.
