The DBH 5155Sil is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. Its dimensions are 25 mm shaft diameter, 52 mm housing diameter, and 10 mm height. The Lz design includes a sealing lip and a dust lip, which helps in environments with moderate dust or moisture. This seal is commonly used in gear reducers, pumps, electric motors, and other industrial machinery. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.

This oil seal is identified by the code 5155Sil and belongs to the DBH brand. The 25 mm shaft diameter, 52 mm housing diameter, and 10 mm height make it a compact option for space-limited assemblies. The Lz designation indicates a sealing lip plus a dust lip, so it handles moderate contaminant exposure. The elastomer and internal spring work together to maintain contact on the rotating shaft. It presses into the housing, and the flexible lip compensates for minor misalignments.

You will find this seal in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors, and power transmission equipment. It also appears in machine tools, conveyors, and hydraulic systems where oil or grease must be retained and bearings protected. The 25 mm shaft size suits compact spaces, as long as the speed and temperature conditions match the seal material.

When selecting a replacement, check that the shaft, housing, and height dimensions match your equipment. The shaft surface should be ground and hard enough to avoid early lip wear. Lubricate the lip before installation and use a tool that won't damage the seal. If your equipment runs at high peripheral speed or extreme temperatures, contact us to review a variant with a different material or design.
