The DBH 5691 is a radial shaft seal built to hold lubricant in place and keep contaminants out of rotating assemblies. Its 38.10 mm shaft diameter, 63.55 mm housing diameter and 12.70 mm height, together with the Mz design, make it a direct fit for common gearbox, pump and transmission bores. MR Industrial Accessories supplies this brand and can help you confirm the right seal for the job.

Reading the designation is the quickest way to confirm a match. The code 5691 identifies the seal itself, while the three measurements describe the bore it sits in: shaft 38.10 mm, housing 63.55 mm, width 12.70 mm. The Mz configuration combines a sealing lip with a metal outer body, which is what allows it to retain oil or grease along a turning shaft. It belongs to the standard range of radial shaft seals and oil seals, so replacements are easy to cross-reference.

Seals of this size turn up in gearboxes, centrifugal pumps, electric motors, rollers and other power transmission equipment. In every case the job is the same: stop lubricant from escaping and block dust, water and particles from getting in. When a seal fails, the bearings and gears behind it wear faster, so this small component has a direct effect on how long the assembly lasts.

Installation is straightforward if the bore and shaft are prepared first. Clean both surfaces, remove burrs and marks, and apply lubricant to the lip before pressing the seal in. When selecting a replacement, account for peripheral speed, operating temperature and the lubricant in use. The Mz design and the listed dimensions fit standard housings. If the shaft itself is worn, an auxiliary lip seal or a repair sleeve is worth considering.
