The DBH 1329 is a radial shaft seal from the DBH line, built to hold lubricant in place and keep dust, water and chips out of rotating assemblies. It fits a 42 mm housing bore with an 8 mm height, and it carries the A 378 lip design. Maintenance teams use this type of seal in gearboxes, motors, pumps and similar equipment where bearings and shafts need protection. MR Industrial Accessories supplies it within its seals and oil seals range.

Reading the code helps when you order. DBH identifies the series, 1329 is the item reference, and A 378 tells you which lip design the seal uses. The published dimensions are housing 42 mm, height 8 mm. The shaft diameter is not stated in the data we have, so confirm it against the manufacturer's data sheet before you commit to a replacement. The seal combines elastomer sealing elements with a metal case, which is what gives it its resistance to abrasion and to the oils normally found in industrial machinery.

These seals turn up in reducers, compressors, spindles, electric motors, pumps and gearboxes, and also in workshops that rebuild machinery. Their job matters: if the lip stops doing its work, lubricant escapes and outside particles get in, and both bearings and shaft surfaces wear faster. Plants in food processing, mining and cement production rely on this kind of component, as do general maintenance shops. Choosing the right seal is one of the simpler ways to keep rotating parts running and avoid unexpected stoppages.

Before fitting one, check that the bore and the shaft are clean and free of burrs or scratches. Put some of the same oil or grease used in the equipment on the lip, then press the seal in evenly with a tube or socket that contacts the outer diameter only, never the lip. Seat it flush or slightly recessed, following the housing design. If the shaft is worn, a repair sleeve or a different size may be the better route. Keep operating speed and temperature within what the seal material allows.

If you need something that works in place of the DBH 1329, get in touch by WhatsApp or email. We can search other brands and series while staying within the housing and shaft tolerances. Sending the full code, the housing, shaft and height measurements, and a photo of the old seal when you have one makes the quote faster. We can also point you to the lip design that best suits your lubricant and operating conditions.
