DBH 5445 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 5445 and any equivalents.

A radial shaft seal in the DBH line, code 5445, built to sit on the shaft and close against the housing bore. It keeps lubricant inside the assembly and keeps dust, water and particles out. The 17.50 x 28.50 x 7.00 mm envelope suits tight axial spaces running at moderate speed.

Reading the designation is straightforward: 17.50 mm is the shaft diameter, 28.50 mm is the housing bore, and 7.00 mm is the overall height. The profile is Lx, a single lip with a metal outer case that presses into the housing. The lip rides on the rotating shaft and may carry a spring depending on how the case is made.

Typical service locations include small electric motors, centrifugal pumps, gear reducers, gearboxes, compressors and other power transmission assemblies. Machine tools, washing equipment and irrigation systems also use this size. The job is always the same: hold oil or grease on the lubricated side and stop it from leaking along the shaft passage.

Before ordering, check three points. The shaft diameter and the housing bore must match the values listed, the height must fit the housing depth, and the lip profile must suit the lubricant in use and the running speed. At installation, coat the lip, press the seal in squarely without hammering it, and confirm the shaft contact zone is free of burrs or wear.

Need a cross-reference? Send code 5445 or the 17.50 x 28.50 x 7.00 mm dimensions and we will check what else fits. We can also review cases with unusual shaft or housing tolerances, or where temperature and speed are demanding.

For a quote, send the code 5445 through WhatsApp or email. If the size is uncertain, include a photo of the old seal or caliper readings, and we will come back with the option that matches your equipment.
