The DBH 5135Sil is a radial shaft seal with a lip and spring, built to keep lubricant in and contaminants out of rotating equipment. It fits a 17 mm shaft, a 30 mm housing bore and a 6.00 mm width, and its Lz design makes it a direct replacement in gearboxes, pumps and low- to medium-power motors. MR Industrial Accessories supplies this seal for maintenance and repair work across the US and Latin America.

The code 5135Sil identifies the seal in catalogs and spare parts lists, so you can match it quickly when ordering. Its three key measurements are shaft 17 mm, housing 30 mm and width 6.00 mm. The Lz configuration means the seal has a sealing lip with a spring, which is the standard choice for rotating shafts that run with oil or grease. Because the lip rides directly on the shaft and the outer diameter presses into the housing, both dimensions have to be respected exactly to avoid leaks.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and power transmission units. Its job is always the same: hold the lubricant inside the assembly and block dust, water or particles from getting in. The compact 6.00 mm width suits equipment where radial space is tight but reliable sealing is still needed at moderate speeds. Machine tools and continuous-process equipment are other common places to find it.

Before installing, confirm the shaft measures 17 mm and the housing bore 30 mm, with enough depth for the 6.00 mm width. The shaft should be ground and free of burrs, and the housing clean and undamaged. Lubricate the lip, then press the seal in with a proper tool rather than striking it, which can deform the metal case. The Lz lip must face the fluid side. If the shaft shows wear, a repair sleeve is an option.
