DBH 5381 radial shaft seal — 70 x 105 x 13

DBH 5381 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 5381 and any equivalents.

When a shaft turns inside a fixed bore, the DBH 5381 radial shaft seal keeps lubricant where it belongs and keeps dust and other contaminants out. The size is defined by a 70 mm shaft, a 105 mm housing bore and a 13.00 mm width, which places it in the range used by gearboxes, pumps and mid-size electric motors. MR Industrial Accessories supplies this brand and helps you confirm the correct seal before you buy.

Reading the code is the fastest way to confirm a match. The 5381 designation pins down one specific size inside the DBH line, and Lz describes how the seal is built: a sealing lip combined with a spring that keeps steady pressure against the shaft. That combination is what allows the seal to hold oil or grease in and block particles from working their way toward bearings and bushings.

Typical installations include gear reducers, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment, as well as agricultural and industrial machinery that runs with oil or grease present. Most of these run with continuous rotation, so the seal is a wear part that is replaced during scheduled maintenance rather than only after a leak appears.

Before fitting a replacement, measure the shaft and the housing bore and compare them with the 70 mm, 105 mm and 13.00 mm figures. The shaft surface should be clean and free of burrs or deep scoring, and a light film of lubricant on the lip helps during installation. The seal goes in with the lip facing the fluid side. If the application involves high peripheral speed or elevated temperatures, tell us so the lip material and spring type can be reviewed.

If you are working from another manufacturer's number, send that code or simply the shaft, housing and height measurements. We cross-reference it and propose a workable equivalent. Because we also handle housings, bearings and power transmission components, we can look at the whole assembly when a seal sits on a bearing position.

Quotes are handled by part number through WhatsApp or email, and our team responds promptly. A photo of the old seal or caliper readings works well when the code is worn off. We serve customers throughout the United States and in several Latin American countries.
