The DBH 6152 is a radial shaft seal that keeps lubricant in and contaminants out of rotating shaft assemblies. Its three key dimensions are 90.00 mm for the shaft, 112.85 mm for the housing bore, and 13.00 mm for the height. The seal presses into the housing and its flexible lip rides on the shaft. In gearboxes, pumps, and motors, this small component often determines how long bearings and gears last.

This seal follows the Mx design: a single lip with a metal case and elastomer element, intended for lubricated rotating shafts. The code 6152 indicates the size within the DBH range. The data sheet lists shaft diameter (d) 90.00 mm, housing diameter (D) 112.85 mm, and height (h) 13.00 mm. Always confirm these three measurements on the shaft and housing before installation; even a few tenths of a millimeter of mismatch will prevent proper sealing.

Typical installations include gear reducers, centrifugal pumps, electric motors, mixers, and conveyors—any place a shaft turns inside a housing with oil or grease. In dirty or wet environments, the lip also blocks dust and water from reaching the bearing. Because it is a wear part, watch for lubricant stains, unusual noise, or shaft play as signs that replacement is due.

Seal selection involves more than the three dimensions. Shaft speed, operating temperature, and the type of lubricant all affect performance. A standard elastomer lip may react differently to hot synthetic oil than to grease. During installation, coat the lip with lubricant, slide it over the shaft using a support sleeve to avoid distortion, and make sure the spring faces the fluid side. If the shaft shows grooves or wear, a wear sleeve or a seal with an auxiliary lip may be needed.

To request a quote, send the complete part number, the shaft, housing, and height dimensions, and a photo of the old seal if available. Our team reviews the DBH line and compatible alternatives. We can also help you determine whether the Mx design suits your application or if a different lip profile or material is required.
