The DBH 5135 is a radial shaft seal that keeps lubricant where it belongs and blocks dust, water and other contaminants from reaching the bearing cavity. Its size is built around a 17 mm shaft, a 30 mm housing bore and a 6.00 mm width, so it fits compact assemblies in pumps, motors, gear reducers and similar machinery. MR Industrial Accessories LLC supplies this line and can help you confirm the correct seal for your application.

The code 5135 identifies this seal within the DBH range. In the size designation, the shaft diameter (d) is 17 mm, the housing diameter (D) is 30 mm and the height (h) is 6.00 mm. The Lz design means a sealing lip with a spring, intended for rotating shafts that run with lubrication. The elastomer lip and the metal case are made to handle continuous friction and hold their sealing function.

You will find this seal in centrifugal pumps, small electric motors, speed reducers, compressors and machine tools. It also appears on transmission shafts, mixers and process equipment where radial space is tight. Because it is a wear part, plan to replace it when you see leaks or hear unusual noise from the area.

Installation is straightforward if you prepare the surfaces first. Clean the shaft and housing, and remove any burrs or scratches. Apply the same oil or grease used in the application to the lip before pressing the seal in. Push it in squarely, putting pressure on the outer diameter only, never on the lip. The spring side must face the fluid being retained. If the shaft is worn, a repair sleeve or a different lip position may be needed.

If you are looking for an equivalent, send the code 5135 or the dimensions 17x30x6 mm, along with the design type (Lz) and what the equipment does. The MR team can suggest options within the DBH line or other compatible alternatives. The final choice still depends on shaft speed, operating temperature and the lubricant in use.

To request a quote, send the part number by WhatsApp or email. If you are unsure whether this is the right replacement, include a photo of the original part or the shaft and housing measurements.
